This summer, researchers will determine whether Crawford Lake should be named the official starting point for this geologic chapter, with pollution-laden sediments from the 1950s marking the transition from the dependable environment of the past to the uncertain new reality humans have created.
In just seven decades, the scientists say, humans have brought about greater changes than they did in more than seven millennia. Never in Earth’s history has the world changed this much, this fast. Never has a single species had the capacity to wreak so much damage — or the chance to prevent so much harm.
“It’s a line in the sand,” said Francine McCarthy, a professor of Earth sciences at Brock University in Ontario, who has led research on Crawford Lake. “The Earth itself is playing by a different rule book. And it’s because of us.”
Canada's Crawford Lake may hold evidence that humans have fundamentally changed Earth enough to have started the Anthropocene, a new chapter in geologic time. https://t.co/AW3StgzJOx
