Americans need to cut beef intake as population grows: World Resources Institute

A growing population means a growing demand for food.

To feed the global population of 10 billion in 2050, the World Resources Institute reports that Americans need to cut beef consumption by 40%.

That means every American could have only 1.5 hamburgers per week.

If developed nations don't cut meat consumption, food demand could outpace population growth.

Farmers may have to produce 56% more crop calories than in 2010.

Beef generates 41% of livestock greenhouse gas emissions.

So cutting down on beef consumption can help pave the way for a sustainable future.
