Oxygen is nice stuff, and most people get grouchy if someone tries to take their oxygen away. So why do we feel ok about suffocating fish and other ocean animals?
This year the Gulf of Mexico dead zone is predicted to set a nasty record. Scientists think the Gulf dead zone will be bigger and badder than ever. More dead animals, more ruined ocean.
All thanks to excess fertilizer that runs off of Iowa's cornfields. Ok, it's not just Iowa and not only corn, but you get the idea. Anyway, the excess fertilizer pours down the Mississippi River and fertilizes the ocean to death. Ugh.
Dead zones are becomming more common, and there may be links to climate change but that's another story.
