Plants buy Earth more time as CO2 makes them grow

Trees and plants are growing bigger and faster in response to the billions of tons of carbon dioxide released into the atmosphere by humans, scientists have found. The increased growth has been discovered in a variety of flora, ranging from tropical rainforests to British sugar beet crops.

March 30, 2009 11:00 AM - Michael Doyle, The Miami Herald

California's struggling dairy farmers will get a modest boost from the Agriculture Department, which announced plans Thursday designed to bolster prices and benefit hungry kids. With dairy prices plummeting, Agriculture Secretary Tom Vilsack said the department will shift 200 million pounds of surplus nonfat dry milk into domestic feeding programs. Reducing the surplus stored in government warehouses is supposed to propel prices upward.

Farmers face growing climate change dilemma: scientist
March 26, 2009 11:39 AM - David Fogarty, Reuters

March 25, 2009 12:03 PM - Science Daily

Better food safety crucial for Africa
March 19, 2009 09:11 AM - SCIDEV

Africa must protect its food supplies from contamination by prioritising and investing in food production systems, says Ruth Oniang'o, editor-in-chief of the African Journal of Food Agriculture Nutrition and Development. January 2009 saw Kenya destroy US$8 million worth of maize — the country's staple food — after it was found to be contaminated with aflatoxin. But it seems the government agency concerned was more worried about recouping storage costs than righting its failures, says Oniang'o.

Why are GM Foods Not Labeled?
March 16, 2009 09:13 AM - My Green Choices

Genetically modified food, also known as GM food or genetically engineered food, entered the food supply in the 1990s. GM foods contain small pieces of foreign DNA (from other organisms and often from another species) however SA companies are not required to label foods that use GM ingredients. The foreign DNA in GM foods is engineered into the food in hopes of producing desirable traits like resistance to herbicides and pesticides, or resistance to specific pests. Insect-resistant maize, for example, is modified by inserting a bacterium gene that produces toxins and acts as an insecticide. Others have a gene that makes them indestructible when sprayed with certain herbicides.

Supreme Court limits advocacy groups' standing to challenge public lands rules
March 4, 2009 09:36 AM - NY Times

Advocacy groups cannot challenge federal regulations on public lands unless they can prove they are themselves directly threatened by the proposed rules, the Supreme Court ruled in a split decision today. In a 5-4 ruling, the justices sided with the Bush administration, which argued that environmental groups do not have the standing to sue the Forest Service on land management policies that might contradict congressional action.
