Fertilizer: An aid in a growing problem
The crops grown in the U.S. use excessive amounts of fertilizer. The chemical fertilizers allow farmers to grow more crops per acre,corn now produces 153 bundles per acre. Farmers average ten millions ton of fertilizer for corn alone, and over twenty-three million for other crops. So what exactly is the cost of all this fertilizer being used in the Mid West for crops? Over 212,000 thousand metric tons of seafood in the Gulf of Mexico. Around the world there are over 400 of these dead zones were there is no oxygen in the water causing the death of sea life. Within the Gulf of Mexico there is a 6,000-sq mile dead zone were very little sea life live and no fishing takes place.
