Yuma, Arizona, along with California’s Imperial Valley, produces more than 90 percent of the country’s winter leafy greens and much of its vegetables. Arizona is also a major grower of wheat, which the state exports to Italy for making pasta. The water that farmers use to grow these crops comes from the Colorado River, and the Colorado River is drying up.

When farmers use less water, they tend to produce less food. And that could cause food prices to go up, even more than they already have. Winter veggies, like lettuce and broccoli, could take a big hit, as could Arizona’s delectable wheat. More concerning still is that the shrinking Colorado River is just one of many climate-related disasters that are threatening the supply and affordability of food.
