Here’s a startling fact: Over 98% of U.S.–produced lettuce is grown in California or Arizona. If you’re scratching your head right now, you wouldn’t be alone: It is indeed baffling that, given that the composition of lettuce is 95% water, it’s primarily being grown in two of the most arid states in the nation.
The agricultural industry is the United States’ largest consumer of water, accounting for 80% of the nation’s consumptive water usage. Today, that number is more relevant than ever, as 18.8% of the lower 48 U.S. states are currently experiencing drought conditions. Water is an incredibly valuable national resource, and should be given the attention that it deserves.
