Humans still aren’t allowed to live in the exclusion zone of Chernobyl, where a nuclear reactor exploded in 1986. Although the radioactivity is dangerous for humans and animals alike, the lack of humans has given some animals an opportunity to thrive.

Wolves in the 2,672 square mile Chernobyl Exclusion Zone in Belarus and Ukraine have adapted surprisingly well to their new human-less existence, despite the threat of radioactivity, a study in the European Journal of Wildlife Research found. They have repopulated the area quickly, enjoying a healthy ecosystem, abundant prey and no humans to shoot them.
