What will the Earth look like in seven years, as climate change progresses, and what we can do about it? That’s the premise of the PBS show Changing Planet, now in its second season, which is tracking six of the world’s most vulnerable ecosystems over the course of seven years. 

In season one, host M. Sanjayan—CEO of Conservation International—travels to the plains of Kenya and the rivers of California to explore the effects of climate change and meet the people fighting against them. In season two, which premiered on April 19, Sanjayan travels to Australia to meet with Aboriginal people training the government in traditional fire-burning practices. This week on Unpacked, we chat with Sanjayan about the importance of Indigenous wisdom, what each of us can do to help support the planet, and how he keeps going when despair looms.
