Growing Environmental Engineers  | Ursula Salmon | TEDxFulbrightPerth
Work with lakes, soils, forests, groundwater, ecosystems! - Come on a journey through the excruciating, exhilarating, and empowering bits of being an environmental engineer. Environmental science is increasingly being translated into computer models, which are then used to predict environmental impacts and guide management decisions. However, no model is perfect! - we need to convince as many brains as possible to choose to OWN the mathematics, to be able to both help make better models and rigorously assess them. Along the way there will be stories of nerdy joy at the little things. Ursula is working towards “creating an army”, particularly around environmental water quality and quantity. After a Chemical Engineering undergrad exchange to Sweden, Ursula stayed on to do a PhD on the environmental impact of mining, and has worked on environmental systems ever since. Projects have included the drought-driven acidification of coastal lakes, how "new" lakes will evolve, and how reactions in soils can impact groundwater and buried infrastructure. Her Fulbright project involved modelling environmental isotopes (e.g., 14C) in groundwater, including the effect of sea level change by ~120m over the last 40,000 y, to assess paleoclimate and improve water resource management tools. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

Hindi Animation on Environmental Impact Assessment (EIA) Process
This documentary seeks to demystify and educate local communities on the EIA process. It uses a storyline to show the importance of EIA process in relation to the community. The story revolves around a village which has been informed that a thermal power plant is proposed to be set up near their village. The villagers are initially happy that the project proponents have offered job opportunity for one person per household for the entire village; however, later they come to know that their livelihood, health and environment could be affected to a great extent if they were not vigilant and this creates fear in their minds. This fear is assuaged by Kathiresan’s son- Muthu’s friend, Jayaprasad, who explains to them about the EIA process notified by the Government, where they could participate in the public consultation process that is mandated under the EIA notification and explains about effectively participating in the public hearing. He also tells them that the project can take off only if all parameters were complied with and EC given, and if there was any problem, they could approach the NGT.

Eco-Rehabilitation of Biodiversity in Forest Destroyed by Gold Miners - TvAgro by Juan Gonzalo Angel
Twitter @juangangel The environmental impact of mining includes erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater, surface water by chemicals from mining processes. In some cases, additional forest logging is done in the vicinity of mines to increase the available room for the storage of the created debris and soil. Besides creating environmental damage, the contamination resulting from leakage of chemicals also affect the health of the local population. Mining companies in some countries are required to follow environmental and rehabilitation codes, ensuring the area mined is returned to close to its original state. Some mining methods may have significant environmental and public health effects. Nuss and Eckelman (2014) provide an overview of the life-cycle wide environmental impacts of metals production associated with 62 metals in year 2008. Erosion of exposed hillsides, mine dumps, tailings dams and resultant siltation of drainages, creeks and rivers can significantly impact the surrounding areas, a prime example being the giant Ok Tedi Mine in Papua New Guinea. In areas of wilderness mining may cause destruction and disturbance of ecosystems and habitats, and in areas of farming it may disturb or destroy productive grazing and croplands. In urbanised environments mining may produce noise pollution, dust pollution and visual pollution. The implantation of a mine is a major habitat modification, and smaller perturbations occurs on an larger scale than exploitation site, mine-waste residuals contamination of the environment for example. Adverse effects can be observed long after the end of the mine activity. Destruction or drastic modification of the original site and anthropogenic substances release can have majors impact on biodiversity in the area. Destruction of the habitat is the main component of biodiversity losses, but direct poisoning caused by mine extracted material, and indirect poisoning through food and water can also affects animals, vegetals and microorganisms. Habitat modification such as pH and temperature modification disturb communities in the area. Endemics species are especially sensitive, since they need really specific environmental conditions. Destruction or slight modification of their habitat put them at the risk of extinction. Habitats can be damaged when there is no enough terrestrial as well by non-chemicals products, such as large rocks from the mines that are discarded in the surrounding landscape with no concern for impacts on natural habitat. Concentration of heavy metals are known to decrease with distance from the mine, and effects on biodiveristy follow the same pattern. Impacts can vary a lot depending on mobility and bioavailability of the contaminant : less mobile molecules will stay inert in the environment while highly mobile molecules will easily move into another compartment or be taken up by organisms. For example, speciation of metals in sediments could modify their bioavailability, and thus their toxicity for aquatic organisms. Bioaccumulation plays an important role in polluted habitats : mining impacts on biodiversity should be, assuming that concentration levels are not high enough to directly kill exposed organisms, greater on the species on top of the food chain because of this phenomenon. Adverse mining effects on biodiversity depends on a great extend on the nature of the contaminant, the level of concentration at which it can be found in the environment, and on the nature of the ecosystem itself. Some species are really resistant to anthropogenic disturbances, while some other will completely disappear from the contaminated zone. Time alone does not seem to allow the habitat to recover completely from the contamination. Remediation takes time, and in most of the cases will not enable the recovery of the diversity present before the mining activity.

24. Population and the Environment
Global Problems of Population Growth (MCDB 150) World population will continue to rise until at least 2050. Environmental impact is the product of the number of people and how much of their income and technology is devoted to either consumption or conservation. So far, the balance is far at the consumption end and, globally, environmental problems are increasing. Environmentalism has not come close to counteracting the footprint of a billion extra people every dozen years. The only massive success has been the decline in global fertility. People want fewer children, the contraceptive technology is available, and the cost is minimal. The only realistic possibility for ameliorating the environmental crisis might be to facilitate the continued decline of fertility. 00:00 - Chapter 1. Course Retrospective 10:26 - Chapter 2.

Population, Sustainability, and Malthus: Crash Course World History 215
In which John Green teaches you about population. So, how many people can reasonably live on the Earth? Thomas Malthus got it totally wrong in the 19th century, but for some reason, he keeps coming up when we talk about population. In 1800, the human population of the Earth passed 1 billion, and Thomas Malthus posited that growth had hit its ceiling, and the population would level off and stop growing. He was totally right. Just kidding, he was totally wrong! There are like 7 billion people on the planet now! John will teach a little about how Malthus made his calculations, and explain how Malthus came up with the wrong answer. As is often the case, it has to do with making projections based on faulty assumptions. Man, people do that a lot.

The Crash Course - Chapter 23 - The Environment - Depleting Resources
Why scarcity will define the future. When we wander over to the third E in this story – the Environment - we note two things: both the increasing demand of exponentially more resources being extracted from the ground and exponentially more waste being put back into various ecosystems. Because we are trying to assess here whether we can justify ever-increasing amounts of money and debt, for now let's just concern ourselves with the resources we take from the natural world to support our global economy. Oil is not the only essential resource that is fast becoming more expensive to produce, harder to find, or both. In fact, we see an alarming number of examples depletion of critical resources that almost exactly mirror the oil story. First we went after the easy and or high quality stuff, then the progressively trickier, deeper and or more dilute stuff. The bottom line is this: we, as a species, all over the globe, have already mined the richest ores, found the easiest energy sources, and farmed the richest soils that our Environment has to offer. We have taken several hundreds of millions of years of natural ore body, fossil energy deposition, aquifer accumulation, soil creation, and animal population growth -- and largely burned through them in the few years since oil was discovered. It is safe to say that in human terms, once these are gone, man, they’re gone. So, if we are getting less and less net energy for our efforts, and the other basic resources we need to support exponential economic growth are requiring a lot more energy to extract because they are depleting, then does it make sense to keep piling up exponentially more money and debt? Isn't it just common sense to observe that money and debt have to exist in some sort of relationship and proportion to primary and secondary wealth?

Goa's Mines Bleed Its Environment Dry
Unmonitored mining has boomed in Goa in recent years and has had dire effects on the environment. The Goa mining industry is thriving, but its impact on nature and the local population is disastrous. 8% of the state surface is already being mined, mostly to extract iron ore that is exported to China. Over 825 mining sites exist throughout the state, and a large number of projects have been given government's clearance. The very large scale and intensive nature of mining exploitation is a serious challenge to Goa's fragile ecosystem. Indeed, 90 % of Goa's mining leases are within notified wildlife sanctuaries and reserve forests. Large areas of fertile agricultural lands have also been diverted for mining. Huge quantities of mining particles are deposited in rivers, contaminating water sources. Devidas Gaonkar, our Community Correspondent in Goa, has been personally affected by the issue. Belonging to a tribal community, he has witnessed how mining exploitation has encroached on natural resources that are so crucial to sustain life in Goa. His village has been flooded recently because of this excessive mining in the area. In his video, Devidas gives us a powerful and articulate description on how mining is impacting the environment. Deforestation due to mining activity is causing soil erosion and siltation, increasing the risk of flooding and impacting ground water, potentially causing water shortage. With his video, Devidas is adding his voice to the chorus of activists who incessantly warn the government against the risk of excessive mining exploitation. Numerous common people like Devidas have also been courageously protesting mining in the streets and blocking vehicles passing through their villages. Devidas wishes his video to similarly raise awareness, with the hope that the government will soon put a halt to large-scale unmonitored mining, which is proving fatal for Goa's vegetation, water and biodiversity.

Public Lecture 2018_February_Andrew Bloodworth
Close to the edge? Approaching new frontiers for mineral and metal resources Population growth, urbanisation and technological transitions are creating increasing demand for minerals and metals. These powerful drivers are likely to sustain this growing material demand up to and beyond the middle of the century. Supply from existing mines can only satisfy demand up to a certain point, after which commodity prices will rise and the market will look for new sources of supply. Commodity price increases also drive innovations in science and technology. These innovations will unlock new metal and mineral resources, pushing development toward the frontiers of possibility. This lecture will explore some of these new resource frontiers and examine the technological, economic, social and environmental factors which may encourage or constrain development. Throughout human history, mining of minerals and metals has always taken place at geographical and technological frontiers, close to the limit of what is possible. Unprecedented material demand has a strong correlation with human-induced environmental change. Are moves toward these new resource frontiers pushing us toward the edge, to the environmental limits of our planet, or do some directions offer the possibility of a more sustainable future? Speaker Andrew Bloodworth, British Geological Survey, Science Director for Minerals and Waste As BGS Science Director for Minerals and Waste, Andrew is responsible for all BGS research related to mineral resources and the geological disposal of radioactive waste. Andrew’s own interests include resource security, critical minerals and the impact of mining on the developing world. He has worked extensively in Africa and was formerly Mining Advisor to the UK Department for International Development. Andrew has been a Fellow since 1995 and a Chartered Geologist.

Solidaridad’s Gold Programme is active in 26 mining communities across 8 countries: Peru, Bolivia, Colombia, Ghana, Argentina, Tanzania, Kenya, and Uganda. Our ASM producer support benefits over 5,200 miners and 35,000 community members. Five communities in Latin America have achieved certification through our support and that of our partners. We work to connect miners in our programme to a market, and were a leading force for the introduction of certified gold in Europe. However, this is just a start. The need for our work is large, due to the rapidly growing number of people who depend on mining and the severity of the issues at mine sites. - See more at: solidaridadnetwork.org/orojusto Solidaridad is an international organization dedicated to responsible food production to feed the growing world population and to providing the world with an alternative to fossil fuels like oil and gas. Solidaridad is convinced that the agricultural sector can produce more efficiently so that it will be able to feed to world population in 2050, as well as supply energy and plastic to the industry. That is why Solidaridad is investing in enterprising farmers in developing countries and putting emphasis on the improvement of their land use so that production can increase while at the same time harm to people and the environment is decreased. Solidaridad focuses on the production chains that matter worldwide and where changes have great impact: coffee, tea, cacao, fruit, textiles, cotton, soy, palm oil, sugar cane, gold and cattle breeding solidaridadnetwork.org

From Saviour To Seeker|A Film On Mother Ganga|Trailer 2| Kumbh| Immaculate Films
- A river is not just flowing water, it is an ecosystem that sustains life. The Ganges with its large basin feeds over 40% of the population of the Indian subcontinent, but we the seekers always exploited her. Its high time we must look for solutions and commitment to save the river, the goddess, the lifeline and the saviour. This film is an effort to unfold all possible facets about the Ganges i.e. historical, mythological, environmental, economic, social, geological, hydrological and many more. A systematic study of the whole issue is essential for a clear understanding of the core problem and for mass awareness as this issue has been talked about yet remained unsolved over past three decades. The Film- The film will cover the Ganges issue in different ways to have a complete view. It will cover the river drainage from start to end i.e. from Gaumukh to Ganganagar including its major tributaries causing damage by their discharge. Various aspects such as pollution, illegal mining, minimum environmental flow, sewage management, industries, agriculture, dependent human population, effect of dam construction, deforestation, sensitivity of Himalayan ecosystem, four lane road construction in the river valley, increased floods and landslides, aquatic life etc. The film will include the perspectives of various field experts like geologist, sociologists, scientists, policy makers, authorities, NGOs and common people. The film will discuss the issues with facts and figures, how the issue must be addressed, the obstacles, policy implementation efforts and outcomes and most importantly the urgent need to save the river. The film is being created by Immaculate Films Private Limited, Delhi. The expected date of completion of the film will be 15 October 2019.

Soil to Sky - Our vision and inspiration
The Ecological Sequestration Trust and the world's first integrated ecological - social and economic systems model http://resilience.io introduced in a short film. Soil to Sky is presented in partnership with the International Centre for Earth Simulation. The film was first presented at the Mansion House in London at the invitation of Fiona Woolf. Our planet, our home is a world of deserts, forests, mountains, wetlands, oceans and complex atmospherics an intricate web of interlocking ecosystems that supports all life, including our own. Yet that life and beauty is under threat. For two hundred thousand years, humanity has thrived on the earth’s natural resources but in the last century our use of them has accelerated to such an extent, that it questions our current model for human development. We have treated success as ever increasing consumption and growth and not accounted for the cost of pollution and natural capital loss. Our world is experiencing the largest wave of urban growth in history. By 2030 5 billion people will be living in towns and cities. Huge investments are being made that will determine living patterns for a hundred years, during which time we will be increasingly affected by global environmental and economic change. But the local conditions can only be accurately taken into account when the global picture is clear. Bob Bishop, founder of the International Centre for Earth Simulation, is bringing together whole earth systems models so that we can understand earth system changes and their impact on city regions. An example is the impact of glacier melt in the Himalayas on river flows in India, China and South East Asia home to nearly 40% of the world’s population. Earth observation satellites provide continuous information about the planet, and the best city-regional models are wired with today’s technology to provide data streams from local sensor networks, smart phones and tablets. Finding a new paradigm for sustainable livelihoods will involve linking global and local systems, it will involve forging an understanding that we, and our towns and cities, do not stand apart from nature but are in a symbiotic relationship with it. Peter Head founder of the Ecological Sequestration Trust is. in partnership with ICES, helping bring all this together for use in city regions. Together, Peter Head and Bob Bishop realised that we need to understand and link the way human and ecological activity interact and impact on our well-being; and based on this knowledge, create the practical tools we need for making decisions and investment choices. Gandhi said there is no point in running fast unless you are running in the right direction. This story is about enabling communities all over the world to find that direction and access the funding to improve human well-being. Surat in India, is a city of 4.3 Million people. A population that is growing at a time when the vital monsoon rains are becoming increasingly unpredictable. To help the city adapt to these challenges, Peter proposed creating an integrated model of the city, so that local people could model the investments that would improve human and ecological health and well-being. In the backstreets of Surat he made a valuable discovery – one which was the inspiration behind The Ecological Sequestration Trust. Surat is a centre for diamond cutting. 80% of the world’s small diamonds are cut and polished here. Peter was surprised to find the factory was a modern five story block, and the work place for 2000 young people, all from a select group of local villages, which compete for process excellence in return for wage and accommodation. Diamond mining involves seeing through dirty, unpromising rock and searching for the beauty and riches that we can create from within. Music BREAK What is true of diamond mining is also true of our run down and unproductive towns and cities. The potential is there, but it needs to be discovered, nurtured and supported using human ingenuity. We try to improve lives, but we use different policies in different nations – we don’t integrate our efforts and people lose hope, even in rich nations. We need to find the valuable jewel within; in the same way that the computer identifies the position of the diamonds within the coarse rock, allowing them to be extracted with lasers, making the process incredibly precise and highly efficient. A combination of advanced technology and highly motivated, skilled people from the villages, creates the diamonds, their value and the wealth of that ultimately supports their communities...

The economical growth has benefited the country in many ways, improving the lives of many citizens. However, the industrialization has been disastrous for the environment and the living conditions of many others. The ground water near Bejing is sinking one meter each year and drought has become a serious problem. Also, water pollution as waste water out of the sewers flows directly into the Liangshui river. Near the idyllic West Lake in Hangzhou, families are fighting the severe air pollution by multiple factories. Is China ready for a clean future, by applying current technological developments on solar and wind energy? Environmental Interest The environmental issues in China discussed in the documentary have a major impact on the biophysical environment as well as human health. Especially the growing amount of motor vehicles and industries such as the coal industry due to rapid industrialization has severe consequences for China and its population. Negative effects are water pollution and water shortages, air pollution, deforestation and desertification. As a result, the Chinese government has undertaken actions, such as implementation of stricter environmental regulations and shutting down of some polluting industries. However, government actions havent been adequate enough. The environmental issues have led to growing concerns and a growing group of Chinese activists, fearing for their environment and living conditions. Promotion of clean energy technology, such as solar energy and wind power has become increasingly important. Solar power is a growing industry for power generation and water heating. Examples are the clean energy urban projects in the Solar Valley in Dezhou city. China is already the largest wind energy provider worldwide. About the Series China on China is an eight-part documentary series dealing with politics and daily life in todays China. After centuries of Western dominance, the world’s center of economic and political weight is shifting eastward. In just 30 years, China has risen from longstanding poverty to being the second largest economy in the world, faster than any other country in history. What China says and does is therefore of great importance to the entire world. The series provides a rare insight into the reinvention of this Eastern superpower.

Conservation Drones
Environmental conservation can be financially and physically challenging wherever it occurs, but particularly so in remote, hard-to-access, or geographically vast areas. Research at the University of Adelaide, however, is making a difference. A team from the University’s Centre for Applied Conservation Science has been investigating the development and use of low-cost unmanned aircraft, or ‘drones’, for conservation-related applications. Their work—including using drones to successfully survey orangutan populations in dense Sumatran rainforests—has attracted global interest, and led to widespread adoption of this transformative technology throughout the environmental sciences. In this informative presentation you’ll hear how the team has done it, the impact their work is having internationally, and how it’s supporting our own conservation needs here in Australia.

The Borax and Boron Miracle 9 - Toxicity Issues
Playlist: https://www.youtube.com/playlist?list=PLpjAxvEG_oO4DRAj41s9h4o7IRylY81fg Toxicity Issues: Government health agencies are concerned about boron toxicity. You might be concerned as well if you read the following, pertaining to sodium chloride or table salt (17): 'Acute oral toxicity (LD50 - the dose at which half of the tested animals die): 3,000 mg/kg [Rat]. Chronic Effects on Humans: Mutagenic for mammalian somatic cells. Slightly hazardous in case of skin contact, ingestion or inhalation. Lowest Published Lethal Oral Dose in Man: 1000 mg/kg. Causes adverse reproductive effects in humans (fetotoxicity, abortion) by intraplacental route, may increase risk of Toxemia of Pregnancy in susceptible women. May cause adverse reproductive effects and birth defects in animals, particularly rats and mice - fetotoxicity, abortion, musculoskeletal abnormalities, and maternal effects (on ovaries, fallopian tubes). May affect genetic material (mutagenic). Ingestion of large quantities can irritate the stomach with nausea and vomiting. May affect behavior (muscle spasicity/contraction, somnolence), sense organs, metabolism, and cardiovascular system. Continued exposure may produce dehydration, internal organ congestion, and coma.' Now compare the sodium chloride toxicity with the Material Safety Data Sheet or MSDS for borax (18): 'Low acute oral toxicity; LD50 in rats 4,500 to 6,000 mg/kg of body weight. Reproductive/developmental toxicity: Animal feeding studies in rat, mouse and dog, at high doses, have demonstrated effects on fertility and testes. Studies with boric acid in the rat, mouse and rabbit, at high doses, demonstrate developmental effects on the fetus, including fetal weight loss and minor skeletal variations. The doses administered were many times in excess of those to which humans would normally be exposed. No evidence of carcinogenicity in mice. No mutagenic activity was observed in a battery of short-term mutagenicity assays. Human epidemiological studies show no increase in pulmonary disease in occupational populations with chronic exposures to borate dust and no effect on fertility.' Here you see that table salt is 50 to 100% more toxic than borax, it changes the genetic material and is mutagenic, while borax is harmless in this regard. Infants are most at risk from high borax ingestion. It has been estimated that 5 to 10 grams can cause severe vomiting, diarrhoea, shock and even death, but it also says that lethal doses are not well documented in the literature. The following toxicity data are from documents of the US Environmental Protection Agency and the Centers for Disease Control(19, 20). A review of 784 accidental human poisonings from 10 - 88 grams of boric acid reported no fatalities, with 88% of cases being asymptomatic, meaning they did not notice anything. However, gastrointestinal, cardiovascular, hepatic, renal, and central nervous system effects, dermatitis, erythema, and death have occasionally been observed in some infants, children and adults exposed to more than 84 mg boron/kg, corresponding to more than 40 grams of borax for 60 kg of body weight. Animal studies have identified reproductive toxicity as the most sensitive effects of boron ingestion. Exposure of rats, mice, and dogs for several weeks showed some damage to the testes and sperm at doses of more than 26 mg boron/kg which corresponds to 15 grams of borax/day for 60 kg body weight. Most at risk is the developing foetus, and in the studied animals rats were most affected. In one study slight reductions in the foetal body weight were already found at 13.7 mg boron/kg/day used during pregnancy. The no effect dose during pregnancy was set at less than 13.7 mg/kg/day corresponding to about 7 grams of borax per day for 60 kg body weight. With an added safety factor a no effect value of 9.6 mg boron/kg/day was calculated corresponding to 5 grams of borax for 60 kg. However, a rat study lasting for 3 generations found no reproductive toxicity or effect on the parents or offspring at 30 mg boron/kg/day. This dose corresponds to 17 grams of borax for 60 kg ingested for 3 generations! In another 3-generation study no problem was found at 17.5 mg boron/kg/day, corresponding to 9 grams of borax/60 kg, while the next higher tested borax dose of 58.5 mg/kg/day, corresponding to 30 grams of borax/60 kg, resulted in infertility. Therefore we can assume that the safe reproductive dose is about 20 grams/60 kg/day. Human studies of the possible association between impaired fertility and high boron levels in water, soil and dust in a Turkish populations, and boron mining and processing workers, found no effect. One study even reported elevated fertility rates in borax production workers as compared to the U.S. national average.

Inside The Three Gorges Dam A Man Made Disaster
When it officially became fully functional on July 4, 2012, China hailed the Three Gorges Dam, the world’s largest power station with 22,500 megawatts of installed capacity as a resounding success. They pointed to it's modern, highly efficient turbines, it's ability to increase shipping capacity along the Yangtze River and the fact that it could help to prevent downstream flooding by freeing up flood storage space. Not only all of this, but it was a move towards limiting greenhouse gas emissions. Sounds great, but, there are two sides to every story and the negative consequences of this monumental project, which cost the country the equivalent of around 25 billion U.S. dollars have been described by many as catastrophic both in its human and environmental impacts. Over one million people were displaced and the dam flooded historically significant archeological and cultural sites. Entire ecosystems were permanently altered with rare plant and animal life being pushed to the brink of extinction. Experts warned that the increased pressure such a massive structure would create on the surrounding land would trigger massive landslides and an increased risk of earthquakes, and their eerie predictions seem to be coming true. We’ll break down the story behind what has become without a doubt one of the most controversial pieces of infrastructure ever built by humankind, The Three Gorges Dam. Subscribe to Knowledge Feed for awesome mysteries, discoveries, fun topics and all around AWESOME videos ! Pros The dam has plenty of positive impacts, it wasn’t built just to cause landslides and displace millions. At full power the Three Gorges is capable of reducing coal consumption by over 30 million tonnes a year, thereby avoiding some 100 million tonnes of gas emissions and ten thousand tonnes of carbon monoxide. The presence of ship locks and even ship elevators believe it or not, allows giant vessels to traverse the Yangtze, boosting the country’s economy as a result. While the Chinese government hoped that the dam would provide power to 10% of people in China electricity demand in the country became much higher than expected and less than 2 percent of the population receive power through the dam today. Another positive impact of the dam, if you were to ask government officials would be it's ability to prevent a very real and very serious threat to the millions surrounding and directly affected by the Yangtze, Floods The Dam’s top priority, it seemed was in preventing the catastrophic floods that occur along the Yangtze, land that is populated by millions of people. In August of 1931 following a year of above average rainfall the Yangtze flooded. 500 square miles surrounding the river were submerged. Entire rice crops were destroyed. Without this essential food thousands in major cities like Nanjing starved following the catastrophe. All told over three and a half million lives were claimed in the months following the floods. More recently in 1998, a series of floods that lasted from June to September left 3,700 people dead, 15 million homeless and caused nearly 25 billion dollars in economic losses. 13 million homes were damaged or broken beyond repair. Now, government officials tout the dams apparent ability to prevent such catastrophes. The general public and especially those that live in areas near the Yangtze aren’t so sure. Flooding last year was the worst since 1998, leaving hundreds dead. Critics pointed to the dam and its failure to prevent the disaster. The 2016 floods were bad and only time will tell if the Three Gorges is capable of preventing an event as devastating as 1998, or scarier still something more along the lines of what transpired in 1931. This dam is so freaking big, some experts out there think it's sheer mass and the changes in water level it creates could actually cause Earthquakes The paths of major fault lines lie directly underneath the Three Gorges. Experts believed that the dam, as a result could cause a significant increase in seismic activity. As you know by now the dam was built despite these and many other concerns, some of which we’ve gone over. A study done by the China Earthquake Administration, a government entity showed that the experts were right. They registered 3,429 earthquakes around the reservoir between mid 2003 and the end of 2009, 30 times the frequency recorded during pre-dam periods. People fear a large earthquake and it's potential consequences as it relates to the dam. If the dam itself were to be damaged during a huge earthquake, for instance, the results would surely be devastating for the millions living in close proximity. Thanks everyone for joining us on our Knowledge Feedy look at the Three Gorges Dam. We hope that we’ve tipped the richter scales within you a bit and we can’t wait for you to join us on our next video. Good night and good luck.

EPA Halts Approval Process For Alaska Mine Project
The Environmental Protection Agency reversed itself on Friday, by halting the approval process for the proposed Pebble Mine copper and gold mine project, which is located in the southwest Alaska’s Bristol Bay region. President Donald Trump has championed increased domestic mining. The Obama administration blocked the proposed mine in 2014 over environmental concerns. Last year, Scott Pruitt reversed that decision, allowing the Canadian company behind the mine project to apply for a permit from the U.S. Army Corps of Engineers. http://feeds.reuters.com/~r/Reuters/domesticNews/~3/sIaepqbGILo/in-reversal-epa-halts-approval-process-for-alaska-mine-project-idUSKBN1FF2ZO http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Quality investments from Lao PDR: organic contract farming in Patxong province
Lao is one of the fastest growing economies in the world. The country offers an attractive investment climate. Tax incentives, policies and law reforms have resulted in a rapid expansion in hydropower, mining, construction and agriculture investments. While economic growth has lifted thousands of people out of poverty, some investments have also come with big environmental and social costs. "We were using a lot of fertilizers. But I started having problems to breath. So I decided to minimize the use of fertilizers." The government of Lao is now working to ensure investments comply with national laws and policies to protect the environment and communities; and to ensurecontract negotiationsresult in equal benefits for all parties concerned. The Poverty-Environment initiative is supporting the government's7th National Social Economic Development Plan that aims to improve the quality of investments. "A quality investment contributes toreducing poverty, enhance development of human capital, have least impact on the environment, support a diversified economy and provide a fair distribution of benefits to the population". Six years ago Mrs Inpeng Samuntee converted her timber company into an organic contract farming businesscultivating coffee and vegetables. Surrounding communities are already benefiting from this win-win initiative. "Within 5-6 years, our lives got better. Now, we got better productions. The vegetables are not going bad anymore. Before, we lived in small cottages. Now we improved our houses." This example demonstrates the impact thatquality investments can have on human development,environmental conservation and the economy on the whole. Globally, organic sales have reached $59.1 billion in 2010with experts forecasting a steady annual growthof 9 per cent or higher. Laos has excellent potential to expand organic production, considering farmers are traditionally accustom to zero chemical production systems, , 75% of the labour force are engaged in agriculture related activities, not to mention the large contribution agriculture makes to GDP. Domestic and foreign investments should be the driving forcebehindfarmers'adoption ofadvanced technologies, knowledge building ofGood Agricultural Practicesand provide the appropriate linkages to rapidly growing GREEN based markets.

Chemical Engineering at Monash University
Chemical engineers invent, design and develop processes that convert raw materials into products, with minimal environmental impact. They are also involved with pollution control, protection of the environment and energy conservation and conversion. Many everyday items involve chemical engineering during some stage of their production: computer chips, mobile phones, petrol, paper and coffee, just to name a few. Chemical engineering has its foundation in chemistry, physics and mathematics, as well as other fields including the applied and biological sciences, and economics. The demand for chemical engineers is increasing as populations grow and resources decline. A degree in Chemical engineering leads to a wide range of careers, traditionally in the chemical, manufacturing, petrochemical and mining industries. But today the demand for chemical engineers is far more extensive, with opportunities in sectors such as computing, electronics, food, clothing and pharmaceuticals.

Mineral Solutions to Global Problems London_Lecture January 2016
The world faces tremendous challenges to resolve the problems associated with climate change and food supply. In both of these, minerals have a vital role to play. To achieve ambitious carbon sequestration targets, of several gigatonnes per year, we have to consider reactions that may take place on a global scale, and one way to do this is to understand and exploit those that take place in soils, recognising the role of plants as a carbon sink both above and below ground that links the soil and the atmosphere. To provide the food required by a population that will increase from 7 to 9 billion by 2050, we need to exploit the natural processes by which soil minerals provide essential plant nutrients as an appropriate companion to conventional fertiliser use. In these and other areas, minerals have a vital role to play in sustaining the human race. Speaker David Manning (GSL President & University of Newcastle) I’ve been a geologist all my life, following an interest that started at a very early age. I learnt much from field work in the Peak District when I was still at school, and then went on to Durham University to read Geology in the days when Sir Malcolm Brown was the Head of Department, before he went on to lead the British Geological Survey. That shows my age. After a wonderful time in Durham (mapping on Rum), I moved to Manchester for my PhD (another wonderful time) which was in experimental petrology – preparing the phase diagram for the system Qz-Ab-Or with added fluorine, or (in other words) establishing how fluorine affects the crystallization of granitic melts. To keep my feet on the ground I did field work in the china clay areas of Cornwall (where F-rich granites occur), and that introduced me to commercial clay geology. I’ve kept that up throughout my career. Postdoctoral fellowships followed – in Manchester (NERC) and then in France (CRPG, Nancy), with experimental work on metal partitioning (tin, tungsten) between granite melt and vapour, and field work in Thailand and Cornwall. Then a few months out of work (but not idle) while waiting to start a New Blood lectureship at Newcastle, and the rest is history as they say. That post involved research on how petroleum source rocks can also be metal ore sources, again experimentally-focused.The Earth Science Review enabled me to move in 1988 to Manchester, with research focusing on clay diagenesis in petroleum systems. Frustrated by an inability to visit a real drilling rig to take oilfield water samples I went to a local landfill and found what I was looking for there – so I worked on landfill clay reactions. Then, in 2000, my evident trajectory to the surface culminated in taking the Chair in Soil Science at Newcastle University, where I work on mineral reactions in soils, reactions associated with carbon capture and nutrient availability for plant growth. Paradoxically, that has taken me into the world of syenites, and their potential as fertilisers. I’m also closely involved with deep geothermal drilling, so mud is still very much part of my daily life.

JSGS Public Lecture~Saskatchewan First Nations and the Province's Resource Future
Presented by Chief Bellegarde, Chief of the Federation of Saskatchewan Indian Nations Saskatchewan is in the middle of an unprecedented resource boom. With oil and gas in the south, potash in central Saskatchewan and uranium in the North, along with promising mineral plays in various locations,Saskatchewan's economy is growing rapidly. First Nations are determined to benefit from the boom, as Treaty Peoples with strong ties to the land and with promises from government that we will benefit from development. With duty to consult and accommodate requirements in place, Saskatchewan First Nations have become national leaders in working out appropriate collaboration and impact and benefit agreements with companies and governments. Much more can be done. More First Nations can be employed on the resource projects. Greater care can be taken to protect our traditional lands and protect our people from harm. There are important business opportunities for First Nations companies that remain to be developed. First Nations will not stand in the way of properly managed development that is based on consultations and agreements with our communities, but nor will First Nations agree to open-ended development strategies that do not return a fair share of the benefits from resource development with the Saskatchewan First Nations.

Manufacturing in space could save life on Earth | James Orsulak | TEDxMileHigh
You care about the future of our planet. You traded in your gas-guzzling SUV for a Prius and your Keurig for a Coffee Maker -- and if enough of us do that, we’ll save the Earth, right? Well, we are dangerously close to collapsing our own ecosystem and we are running out of time. In this persuasive talk, James Orsulak argues that the only way to really make a difference is to look up. James Orsulak serves as the Director of Business Development at Planetary Resources, an asteroid mining company that has embarked on the world’s first commercial deep space exploration. The company focuses on technologies such as rocket propellant, water for life support functions, and construction materials sourced from asteroids. Previously, James spent a decade developing industrial-scale fueling stations on Earth. He is an avid gardener who lives in Denver with his amazing wife, 2-year-old twins and a rambunctious Goldendoodle named Waffles. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
