Rat poisons endanger California wildlife
November 5, 2015 08:13 AM - Center for Biological Diversity
Researchers at the University of California released a study today indicating that rat poisons increasingly pose a significant risk for California’s imperiled Pacific fishers, small, forest-dwelling mammals that are protected under the California Endangered Species Act. The study shows that increasing numbers of fishers are being exposed to, and dying from, greater varieties of rat poisons, or rodenticides, found at illegal marijuana farms. It also affirms reports and data from across the state that rodenticides continue to poison and kill numerous California wildlife species.
“These poisons are silently killing our country’s most majestic wildlife by indiscriminately causing animals to literally bleed to death from the inside out,” said Jonathan Evans, environmental health legal director at the Center for Biological Diversity. “It’s time to ban these poisons from the market to protect fishers, bald eagles, great horned owls and kit foxes from a painful, gruesome fate.”
Historic Nitrate Levels Still Plague U.S. Rivers
October 29, 2015 06:16 AM - USGS Newsroom
During 1945 to 1980, nitrate levels in large U.S. rivers increased up to fivefold in intensively managed agricultural areas of the Midwest, according to a new U.S. Geological Survey study. In recent decades, nitrate changes have been smaller and levels have remained high in most of the rivers studied.
Arsenic found in many US red wines
October 7, 2015 09:11 AM - Jennifer Langston, University of Washington
A new University of Washington study that tested 65 wines from America’s top four wine-producing states — California, Washington, New York and Oregon — found all but one have arsenic levels that exceed what’s allowed in drinking water.
The U.S. Environmental Protection Agency allows drinking water to contain no more than 10 parts per billion of arsenic. The wine samples ranged from 10 to 76 parts per billion, with an average of 24 parts per billion.
Sierra Nevada snowpack at historic low
October 3, 2015 06:52 AM - Mike Gaworecki , MONGABAY.COM
On April 1, California Governor Jerry Brown stood in a Sierra Nevada meadow atop parched, brown grass — at an elevation of 6,800 feet, where there would normally be five feet of snow at that time of year — and announced the state’s first-ever mandatory water restrictions.
The Golden State is still in the grip of a severe drought that began in 2012, and new research suggests it is one of the worst in centuries.
The day Gov. Brown announced the statewide water restrictions, snowpack in the Sierra Nevadas was reported to be at just 5 percent of its historical average, as calculated from records dating back to the 1930s.
Insect protein and our food
September 27, 2015 07:00 AM - Laurie Balbo, Green Prophet
A start-up business focused on finding new ways of using insect protein in food products is a finalist in this year’s MassChallenge, the Boston-based start-up competition and world’s largest accelerator program. Get over your squeamishness, because bug-based foods will soon infest our markets.
The “elevator pitch” for Israel-based The Flying Spark states their intent to manufacture protein powder based on insect larvae that can be added to a wide range of food products, replacing today’s protein powders – commonly made from whey, soy, or casein. Insects contain extremely high protein, fiber, micro-nutrients and mineral content. They’re also naturally low in fat, and cholesterol-free. The tipping point for this product’s potential is that insect protein will cost less to produce than any other source of animal protein.
Pesticide use leads to endocrine disrupters in French lettuce
September 25, 2015 07:33 AM - Journal de environnement by Romain Loury translated by Samuel White via EurActiv
An investigation has found that the majority of French lettuce contains traces of hormone disrupting chemicals, some of which are banned. Journal de l Environnement reports.
The French NGO Générations Futures released the results of an inquiry into chemical contamination in food products on Tuesday (22 September). After examining the contaminants in strawberries in July 2013, the NGO published a report this week entitled EXPPERT 5, examining lettuce, the fourth most popular vegetable in France.
The findings were less than impressive: of the 31 products bought in supermarkets in the French departments of the Oise and the Somme, grown on conventional farms, over 77% contained traces of at least two pesticides, and only 19% were pesticide-free.
Is fracking water safe to irrigate crops?
August 24, 2015 06:35 AM - Crystal Shepeard, Care2
The race to find cleaner energy sources has led to a boon in hydraulic fracturing (“fracking”) in search of natural gas. Highly pressurized chemicals and water are pumped deep underground to break shale and release natural gas for harvesting. Residents and environmentalists have long been opposed to the process, which has seen an increase of health issues due to contaminated water. In drought stricken California, there is also concern about the amount of water being used in fracking operations, as well as what is done with the wastewater.
California farmers are frustrated with oil companies that have encroached on their areas. Fertile farm land is also filled with natural gas and there has been an increase in fracking operations. As the name implies, hyrdraulic fracturing is a water-intensive process. At the front-end, freshwater is infused with chemicals and is pumped into the shale. This has put farmers and oil companies in competition for the ever decreasing amount of water available.
Scientists discover what causes soil acidification

Australian and Chinese scientists have made significant progress in determining what causes soil acidification – a discovery that could assist in turning back the clock on degraded croplands.
How will global food supply be affected by climate change?
August 19, 2015 08:05 AM - Erik Stokstad, Science/AAAS
In 2007, drought struck the bread baskets of Europe, Russia, Canada, and Australia. Global grain stocks were already scant, so wheat prices began to rise rapidly. When countries put up trade barriers to keep their own harvests from being exported, prices doubled, according to an index of the Food and Agriculture Organization of the United Nations. Just 3 years later, another spike in food prices contributed to the Arab Spring uprisings. Such weather-related crop disasters will become more likely with climate change, warns a detailed report released today by the Global Food Security (GFS) program, a network of public research funding agencies in the United Kingdom.
Dissecting the Farm-to-Table Fable
August 18, 2015 09:17 AM - Jan Lee, Triple Pundit
The vibrant, mega-million-dollar farm to table movement is under increasing scrutiny these days. In San Diego, where produce is an $1.8 billion industry and year-round farmers markets can be found in almost every neighborhood (one of the few financial spinoffs of climate change, perhaps), the farm-to-table concept is getting a bad rep.
