Fossils embedded in rock reveal intriguing details about animals, plants and other life-forms that once called Earth home. ConsequencesCrawford Lake in Ontario is the geological site that best reflects a new epoch recognizing the impact of human activity on Earth, said geologists of the Anthropocene Working Group. The Anthropocene Working Group determined in 2016 that the epoch began around 1950 — the start of the era of nuclear testing. The international research group says that Crawford Lake in Ontario best charts humanity’s impact on Earth. Back then, it took 10 hours to relay a single image to Earth — incredibly slow by today’s standards.
