In this age of climate change, species extinction and exponentially expanding human population, it's hard not to feel like we're doomed. So it's important that we find voices to listen to that offer some glimmers of hope. On this episode of Locus Focus we are joined again by writer and marine conservationist Carl Safina, who has witnessed as well as anyone, how much damage results from too many humans obsessed with using up every ounce of our planet's natural resources without concern for future generations. Yet Safina remains a voice of hope as he searches for examples of what is working. His writing offers models for how we can re-orient our values, visions and practices of living on the earth like we are part of its natural systems.
