"Mother Nature's" Melting Pot - rethinking non-native species - 0 views

Micah Leinbach on 03 Apr 11Connecting immigration sentiments to the anti-invasive fervor of environmentalists (a stylistic, more than a substantive trick, I think) this writer questions the war against non-native species, citing the dynamic and evershifting nature of, well, "nature." I appreciate the sentiment and the focus more on the function of ecological systems, rather than its ever-shifting make up (species lists being as much a burden to ecological thought as a blessing), but its a hard line to tread when you start picking which non-natives and which natives to battle. Zebra mussels, for example, were cited in the piece as lake-cleaning food sources for many small fish and in turn birds. This is true, most research shows that the zebra mussel is becoming a major food source around the great lakes. But is it an improvement? It is a difference, certainly. From a human perspective, its much worse: even beyond the obvious decimation of fishing industries (note the author says it increases populations of SMALL fish), try walking barefoot on a beach cluttered with the remains of zebra mussels. No fun. Lots of blood. Whole generations forced to wear water shoes where bare feet once sufficed. So, if we're forced into acknowledging that we can't rely on the essences of stable-state ecosystems as our guide to how ecological systems should be, what do we use? And can we (should we?) get past anthropocentrism (maybe I should sacrifice my feet, the fishing industry, and the various non-human populations of organisms getting hit by zebra mussels for the zebra mussels, small fish, and birds) in doing so? This is a big question, and I definitely don't have any great answers. But its worth pondering.
