Nice share. Before clicking, I thought this was gonna be about invasive species and growing, declining, and drifting populations. Think for example, barred owls expanding west or coyotes expanding east, asian carp, etc. That said, this article does bring to mind a conversation I had a while back with someone who was convinced that as far as the environment was concerned, Chernobyl was a net benefit. It was interesting to try and figure things out because on the one hand, the reduction in human activity gave the natural environment room to grow, but on the other hand, radiation is obviously no bueno and it doesn't just disappear or dissipate over night and we're still, decades later, trying to figure out how and how much it has affected the soil, water, plants, and animals in the area.
