b"Planet earth is beginning a new geological age, or epoch, scientists are calling the anthropocene.\\nThis new stage reflects the warming atmosphere, changes in plant and animal populations and severe weather. \\nWhen a new geological age starts, scientists look for a place that clearly shows the transition from one to the other.\\nFor the anthropocene, that place could be Crawford Lake in Ontario.\\nFrancine McCarthy is a professor of earth science at Brock University, and an expert on Crawford Lake.\\nShe spoke with CBC's Leigh Anne Power."
