On average, Americans eat a national total of nearly 50 billion burgers per year. How do cows impact negatively affect the environment?
+ It takes 1,800 gallons of water to produce one pound of grain-fed beef.
+ We use eight times more land to feed animals in the U.S. than we use to feed humans.
+ The 17 billion pounds of fertilizer used to grow feed for cows flows into rivers and oceans, creating huge algae blooms where nothing can survive.
+ In total, 6.5 pounds of greenhouse gases are released to produce just one quarter-pounder burger.
