A conversation with Pulitzer Prize winner Elizabeth Kolbert on the subject of the health of our planet. The world is in serious crisis. Rising sea levels, destruction of habitat, loss of farmland, and a host of other outcomes of climate change are destroying the earth’s ecology and could destroy its most dangerous interloper, homo sapiens. Elizabeth Kolbert, a staff writer for the New Yorker magazine and author of the 2015 Pulitzer Prize-winning book, The Sixth Extinction: An Unnatural History, has devoted years of travel, research, and writing to the situation and what we can do to get back on course. Kolbert brought her message as a Master Series speaker to the Greenbuild International Conference and Expo, on Thursday, November 19, in her talk, “The Sixth Extinction.”
