Some scientists believe human activity and technology have pushed us into a new geological epoch called the Anthropocene. What they still need to figure out though, is exactly when this turning point began.
A team of researchers from three universities in Ontario is betting the answer lies at the bottom of a lake in Milton, just west of Toronto.
“We feel strongly that Crawford Lake has all the right stuff,” said Francine McCarthy, the team’s leader and an earth sciences professor at Brock University who has been studying the lake since the 1980s.
She says Crawford Lake is an ideal place to take sediment samples because it is 22-metres deep and anoxic, meaning there’s no oxygen at the bottom, so nothing lives down
