The Environmental Impact of Beef

A rigorous study published in June in the Proceedings of The National Academy of Sciences suggests that beef production is much more damaging to the environment than the production of other sources of protein. 

Beef production uses 28 times more land and 11 times more irrigation water than production of protein sources lower on  the food chain like poultry, eggs and even dairy.  Beef production is also responsible for much larger emissions of greenhouse gases and consumes much larger amounts of nitrogen than other forms of protein production.

The study suggests that cutting down on red meat would have a bigger impact on carbon reduction than abandoning cars.

Serious stuff.
