This week we bring you an intergenerational conversation featuring David Suzuki, who is a Canadian scientist, activist, and media figure. Since the 1970s, Suzuki has hosted both radio and television shows about the natural world and environmental issues. A self-described “elder,” Suzuki shares his views and long-term perspective on environmentalism with our producer Mike Osborne. Their wide-ranging conversation spans climate change, energy, shortfalls of the environmental movement, and the evolving relationship between humans and Earth’s ecosystems.
