"A species may eat a particular bacterium, phytoplankton, smaller fish, or plant in an area. Lacking a predator, these species/populations will overgrow and alter the area's biology, overwhelming and driving to extinction dozens or hundreds or thousands of other local species."

Ours is certainly not an old culture. Yet in recent decades we've used more energy, destroyed more soil, created more pathogenicity (temporarily stopped some too, for sure), mutated more bacteria, and dumped more toxicity on the planet than all the cultures before us-combined. I love the United States, but I am not blind to the wrongs. I have no desire to live anywhere else, but that doesn't mean I think everything we're doing should be done or can be maintained.
