When you throw away food, a lot of resources are being wasted that you don’t actually see. “People don’t fully understand what’s required to make the food they’re eating,” says Jennifer Schmitt, a biologist at the University of Minnesota. “When studying food waste, you look at what’s wasted along the whole supply chain—from growers, processors, retailers, and consumers.”
It takes manual labor, water, fuel, fertilizers, containers, and other resources to make the food we eat. When a package of strawberries goes bad in the fridge, all of the resources that went into growing, packaging, and transporting the fruit are wasted too.
According to a report from the University of Minnesota, producing uneaten food wastes about 25 percent of cropland, 20 percent of fertilizer, and as much as 15 percent of the water used to grow food in the U.S. In addition, about 2 percent of all energy produced in the U.S. goes toward making food that’s just thrown away. But the harmful effects of wasted food don’t end once it’s in the garbage.
