Mercury Thermostats Most home thermostats contain a few grams of mercury. Although they only contain small quantities of mercury and do not by themselves exceed any regulatory threshold, they contain enough mercury to potentially cause a significant health risk. The state of California has issued new rules that will greatly reduce the amount of dangerous mercury sent to landfills and incinerators each year due to the improper disposal of old mercury-laden thermostats. The new rules will require thermostat manufacturers to collect and recycle the vast majority of discarded mercury thermostats in California. Over the next five years, this will keep nearly 2 tons of the toxin out of garbage trucks, landfills and incinerators where the mercury can be released from crushing or burning, according to the Natural Resources Defense Council, the California Product Stewardship Council, and the California Sierra Club.
India's hornbill conservator is awarded the "Green Oscar" The Whitley Awards is a prestigious international prize awarded annually to individuals working in nature conservation at a grassroots level. They were first awarded in 1994 and over the past two decades, the Whitley fund for nature has given almost £10 million ($15 million USD) to conservation and recognized 160 conservation leaders in more than 70 countries. These awards are known as the 'Green Oscars' and are often awarded to conservationists working in conflict-torn and developing countries. This year, the prestigious prize was awarded to Aparajita Datta's project, "threatened hornbills as icons for the conservation of the Himalayan forests of Arunachal Pradesh, India".
What is Causing the Big Shrimp Die-Off in Asian Shrimp Farms? A cause of a mysterious disease devastating shrimp farms across Asia since 2009 has been tracked back to a strain of a bacteria native to coastlines around the world.
The shrimp early mortality syndrome has perplexed experts for years, in a region where roughly one million people depend on shrimp farming for survival.
So far countries officially reporting the disease — also referred to as acute hepatopancreatic necrosis syndrome — include China, Malaysia, Thailand and Vietnam, but potentially it could affect shrimp farming further afield in Asia, as well as parts of Latin America and Africa.
Sneaker Life Cycle Impact The American term sneakers refers to footwear with a flexible sole made of rubber or synthetic material and an upper part made of leather or canvas. Sneakers were originally sporting apparel, but today are worn much more widely as casual footwear. A typical pair of running shoes generates 30 pounds of carbon dioxide emissions, equivalent to keeping a 100-watt light bulb on for one week, according to a new MIT-led life cycle assessment. A life cycle measures the environmental impact of the raw materials, processing, and transport to the final market as well as waste disposal. But what’s surprising to researchers isn’t the size of a shoe’s carbon footprint, but where the majority of that footprint comes from.
African soil diversity mapped for the first time A team of international experts has drawn up the Soil Atlas of Africa — the first such book mapping this key natural resource — to help farmers, land managers and policymakers understand the diversity and importance of soil and the need to manage it through sustainable use. They say that despite soil's importance, most people in Africa lack knowledge about it, partly because information about it tends to be confined to academic publications read only by scientists.
