Will the government step in and start regulating these chemical tools? Earlier this fall, researchers from the National Institute of Health finished up a landmark 20-year study, a study that hasn’t received the amount of coverage it deserves. 13 Reasons Tea Is (Healthy and) Awesome: Greatist.com.

But before loading up on Red Zinger, make sure that your “tea” is actually tea. Real tea is derived from a particular plant (Camellia sinensis) and includes only four varieties: green, black, white, and oolong. Anything else (like herbal “tea”) is an infusion of a different plant and isn’t technically tea. But what real tea lacks in variety, it makes up for with some serious health benefits.

Researchers attribute tea’s health properties to polyphenols (a type of antioxidant) and phytochemicals. Farm kills millions of bees with illegal pesticide spraying, gets slap on wrist. The U.S. Navy Just Announced The End Of Big Oil And No One Noticed - Surf’s up!

Even before last week's chemical spill fouled tap water in nine counties in West Virginia, where more than 200,000 people still cannot use their water after seven long days, it was not unusual to find black water running from kitchen faucets in homes outside Charleston.

Or to see children with chronic skin rashes. Or bathtub enamel eaten away, leaving locals to wonder what the same water was doing to their teeth. "Welcome to our world," says Vivian Stockman, 52, a longtime resident of rural Roane County, north of Charleston, the state capital, and an activist with the Ohio Valley Environmental Coalition.

Indeed, people who live in the Kanawha River Valley, which much of the world learned recently is also known as Chemical Valley, have endured a long history of pollution of many kinds.

The real threat to our future is peak water. Start-up promises to revolutionise shrimp farming. A UK start-up says it has developed a low-cost, ecological alternative to traditional shrimp farming by using bacteria as both a water filter and food for its shrimp.

Start-up promises to revolutionise shrimp farming

IKEA-like portable units using microbes and solar power to cheaply grow shrimp indoors could transform the booming aquaculture sector and prevent further environmental degradation, according to its inventors. If made available to farmers in developing countries, the technology could help tackle malnourishment while reducing environmental degradation, and all at a lower cost than current shrimp production, they say. Founded by biochemical engineering students from University College London, the start-up Marizca is producing whiteleg shrimp in central London in its first trial operations.

Global production of farmed shrimp has been growing at about ten per cent a year, according to conservation charity the World Wildlife Fund, and farmed shrimp now accounts for about 55 per cent of global shrimp production. Can Wave Power Really Make Waves Against Fossil Fuels? About 15 years ago, the state of Oregon “began pushing the idea of making renewable energy from the ocean waves that bob and swell on the Pacific horizon,” reports The New York Times.

Eco-Friendly Farming: Sowing the Seeds of Renewable Energy. Twelve percent of global greenhouse gas emissions come from agriculture, and six to nine percent of farm expenses are energy related.

Eco-Friendly Farming: Sowing the Seeds of Renewable Energy

Using renewable energy in agriculture has benefits for both the economy and the environment, and many farms around the world are using the abundance of on-site renewable resources to produce energy. Here is a look at how renewable energy – from solar power to microbial digestion – is changing the future of agriculture. Photosynthesis to Photovoltaics With expanses of land and a need to source power to remote locations, solar energy is well-suited for life on the farm.

In the United States, the number of solar projects on farms funded by the USDA’s REAP program increased fivefold between 2007 and 2009, according to a report by the USDA (pdf). Drought may yield benefits for wineries and wine lovers. Nestled on a hillside in northern Virginia, Breaux Vineyards' 105 acres of vines are looking good this year, according to General Manager Chris Blosser. While California still makes the vast majority of American wine, all 50 states produce it. Virginians have been growing grapes for some 400 years, starting in the Jamestown settlement, and the wine business has surged in the state over the last decade. Soil and climate conditions in Loudoun County, where this family-owned vineyard is located, make it one of Virginia's top wine-producing regions. The drought plaguing much of the country has hurt corn and soy crops, with the U.S. Department of Agriculture estimating that 2012-2013 corn yields would hit the lowest level since 1995-1996.

Clarified: What does "organic" mean? In cooking, the process of clarification entails straining out extraneous muck from liquids so that they might be pure, clear and ideal for consumption. With this series on food terminology and issues we're attempting to do the same. Organic: it's a word that gets bandied and bashed around a lot. Plenty of folks believe it's synonymous with "healthy," while others think it's just an excuse for companies to vacuum the last of the cash from your wallet. Politics aside, what does the term actually mean? Produce: Organic produce is grown without the use of synthetic fertilizers, sewage sludge, irradiation, and genetic engineering, and relies on natural or mechanical methods, rather than prohibited chemicals, for pest control. Growing populations of brown marmorated stink bug could harm late-season crops.

CORVALLIS, Ore. – Oregon State University researchers warn of an increased risk of damage to late-ripening crops this year after discovering record levels of the brown marmorated stink bug, a newly established invasive pest in Oregon. Why 2013 will be a year of crisis. The Drought and the Gulf of Mexico Dead Zone. Dead zones are hypoxic (low-oxygen) areas in the world's oceans and large lakes, caused by "excessive nutrient pollution from human activities coupled with other factors that deplete the oxygen required to support most marine life in bottom and near-bottom water. Currently, the Gulf of Mexico's dead zone, off the coast of Louisiana and Texas, is the most notorious hypoxic zone in the United States. The worst drought to hit the United States in at least 50 years does have one benefit: it has created the smallest dead zone in the Gulf of Mexico in years, says a Texas A&M University researcher who has just returned from gulf waters.
