Interesting to see that wild life is making a big comeback in the radioactive Chernobyl region. Reading the article it sounds like the DNA was mutated but has had little visible effect on most of the animal species. While the lack of humans, and human associated materials such as pesticides has helped the animals which are apparently to radioactive to eat.
Amusing suggestion at the bottom is that maybe nuclear waste should be stored in regions where the ecology is endangered It'll kill or scare off the humans and leave the animals alone after the initial die back of those who can't adapt.
Wildlife defies Chernobyl radiation
