The July 2005 issue of Physics World states: “The animals we eat emit 21 percent of all the CO2 that can be attributed to human activity.” Eating meat directly contributes to this environmentally irresponsible industry and the dire threat of global warming.
Additionally, rainforests are being cut down at an extremely rapid rate to both pasture cows and grow soybeans to feed cows. The clear-cutting of trees in the rainforest — an incredibly bio-diverse area with 90 percent of all species on Earth — not only creates more greenhouse gases through the process of destruction, but also reduces the amazing benefits that those trees provide. Rainforests have been called the “lungs of the Earth,” because they filter our air by absorbing CO2, while emitting life-supporting oxygen.
"In a nutshell," according to the Center for International Forestry Research, "cattle ranchers are making mincement out of Brazil's Amazon rainforests."
