When bad things happen to good ecosystems: Lake lessons from the Gulf
|
By Jane Elder
Right now we’re watching a really bad petroleum-based horror story play out in the Gulf of Mexico. All things considered, this is a really good ecosystem, even though it has known some hard knocks, like being home to the world’s largest marine dead zone, thanks to all the chemical fertilizers and semi-treated sewage that our great heartland has flushed down the Mississippi River for decades. Where the zones aren’t dead, the Gulf and its coast have been one of our hemisphere’s most productive marine habitats. This foodweb with delectable species supports not just the fishing and restaurant trade, but pelicans, dolphins, sea turtles and countless other living creatures large and small. Where the water meets the land, nature has given us mangroves, islands, emerald beaches — all pretty splendid stuff, and remarkable habitat.
