A Food Contradiction

I was reading today on CNN that oceanic dead zones are increasing rapidly and becoming a global problem. One of the biggest contributors to the growth of dead zones is the use of large amounts of fertilizer which eventually leech off the land and into the water, eventually traveling to the sea. Corn, which is the largest crop in the U.S., is especially fertilizer intensive. When in the ocean, this fertilizer causes the production of huge algae blooms which starve the water of oxygen, killing the seafood around it. So basically in the quest to grow more and more grain to feed the population of the world, we are inadvertently killing the seafood we depend on as well. If it continues, we would see a future when a seafood meal would be a very rare delicacy, something the average person could not even experience. Being a person who loves to eat Maryland crab, this is a very sobering thought indeed.
