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. Producing a kilo of beef causes the equivalent of 36.4 kilos in carbon dioxide (CO2), the principal greenhouse gas, Mr Ogino found. Most of these greenhouse-gas emissions take the form of methane, released from the cow's digestive system. That one kilo 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 per cent less greenhouse gases and consumes 85 per cent 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. -- AFP -- Fight captive Jumbo abuse, end Elephant Polo http://www.stopelephantpolo.com Quote Link to comment Share on other sites More sharing options...
