Plutonium from nuclear weapons, industrial waste, and human activity more broadly have left such a mark on the Earth that a new epoch called the Anthropocene has been proposed. Scientists are debating the specific geological site to define this epoch, with the frontrunner being an unassuming lake in Canada: Crawford Lake.
