Scientists believe that the sediment layers of a lake in Canada point to a new era marked by the damaging consequences of human activities.
As global demand for wood products is projected to rise over the coming decades, the world is expected to log about 3 million square miles of forestland.
Because Crawford Lake is 79 feet deep but only 25,800 square feet in area, the layers on the lake bottom are pristine showing what’s in air and on Earth each year, scientists said. Jurgen Renn, who wasn’t part of the study group but directs the Max Planck Institute for the History of Science in Berlin, said humans also “need that power, our knowledge, our technologies, but also our capacities of making better societies” to lessen and adapt to the worst consequences of our actions.
It also starts a new age. It’s named Crawfordian after the lake chosen as the starting point, and ends the Meghalayan Age that started 4,200 years ago, Waters said.

Canadian lake sediments reveal start of Earth's Anthropocene age, scientists saySediment deposited at Crawford Lake, a small but deep body of water in Canada's Ontario province, provides unmistakable evidence that Earth entered a new human-driven geological chapter - the Anthropocene epoch - some seven decades ago, a team of scientists said on Tuesday.

Scientists now say a new epoch – the Anthropocene, marked by human impact on Earth – began in 1950sThe burning of coal, oil and gas that’s changing Earth’s climate and atmosphere, nuclear bomb detonations spotted in soil around the globe, plastics and nitrogen from fertilizers added on land and dramatic changes to species that make up the rest of the Earth characterize the new epoch, scientists said.
