"We're no acme or pinnacle of anything, we're just simply evolutionary steps," says this week's "World We Want" podcast guest, Dr. Gabriel Filippelli, of the human hubris surrounding climate change. In a long conversation, Márcia Balisciano and Dr. Filippeli, author of Climate Change and Life, touch upon the history of the world, both in terms of climate change and in the patterns of evolution and extinction, as well as what the presently changing climate means for human beings. Balancing pragmatism and optimism, this episode serves as a stark look at the reality of climate change and the will—political, environmental, and personal—needed to adapt.
