For evidence of this, we can look to areas of the planet that we’ve been forced to vacate. In the 19-mile exclusion zone surrounding the Chornobyl power plant in Ukraine, which was severely contaminated following the 1986 reactor meltdown, plants and animals are thriving in ways they never did before.
