Eat A Steak, Warm The Planet
Paris (AFP) July 18, 2007 A kilogram (2.2 pounds) of beef causes more greenhouse-gas and other pollution than driving for three hours while leaving all the lights on back home, according to a Japanese study. A team led by Akifumi Ogino of the National Institute of Livestock and Grassland Science in Tsukuba, calculated the environmental cost of raising cattle through conventional farming, slaughtering the animal and distributing the meat, New Scientist reports in next Saturday's issue. Producing a kilo (2.2 pounds) of beef causes the equivalent of 36.4 kilos (80.08 pounds) in carbon dioxide (CO2), the principal greenhouse gas, Ogino found. Most of these greenhouse-gas emissions take the form of methane, released from the cow's digestive system. That one kilo (2.2 pounds) of beef also requires energy equivalent to lighting a 100-watt bulb for nearly 20 days. The energy is needed to produce and transport the animals' feed. A Swedish study in 2003 suggested that organic beef emits 40 percent less greenhouse gases and consumes 85 percent less energy because the animal is raised on grass rather than concentrated feed. The study appears in full in a specialist publication, Animal Science Journal.

Organic Farming Can Feed the World
Ann Arbor MI (SPX) Jul 16, 2007Organic farming can yield up to three times as much food as conventional farming on the same amount of land---according to new findings which refute the long-standing assumption that organic farming methods cannot produce enough food to feed the global population. |
