Think about not wasting land on animal agriculture

I came across this slick video from the World Wildlife Fund on how our methods of food production tie into our growing population.

The video shares some grim statistics, and talks about how we need to get more out of what land we have.

This ultimately comes down to reducing our dependence on animal agriculture, though the video does not mention this. 

Livestock use 30% of the earth’s surface. According to Cornell University, the US could feed 880 million people with the grain that livestock eat:

…beef cattle production requires an energy input to protein output ratio of 54:1(Lamb meat production is nearly as inefficient at 50:1, according to the ecologist’s analysis of U.S. Department of Agriculture statistics. Other ratios range from 13:1 for turkey meat and 14:1 for milk protein to 17:1 for pork and 26:1 for eggs.)

The solution is not finding more efficient crops — it’s to stop wasting land that could be used for food sources that are more calorie-efficient than meat, eggs, and dairy.
