The direct human impact of hurricane Katrina is not yet over, but this morning Rebecca Claren posted an article on Salon about the layers of environmental damage that demand attention. But where do we turn first? For starters, there are the waterborne bacteria from human and organic waste that have already caused four deaths in New Orleans. Next, further in the future but much more dangerous and (difficult to deal with), are the petrochemicals lining the floodwaters with a lingering film of toxic sludge. Then there are the marshlands and protective wetlands, which Clarren describes as a “sea of mud.” Or do those come before the sludge? One thing’s for sure–it’s going to be tough to prioritize long-term health and environmental damage from Katrina. For maybe the first time, the Society of Environmental Journalists has released its own official op-ed in response to what Dave Roberts on Grist calls “official stonewalling on the environmental damage done by Katrina”.
