Description

The Bay Area is a biodiversity hotspot, home to species found nowhere else on Earth. But decades of urbanization have pushed many of these animals — and the ecosystems they depend on — to the edge. Can science bring them back? In this episode, we examine the remarkable comeback of the southern sea otter and an ongoing effort to resurrect the long lost Xerces blue butterfly.
