Coast as systems-of-systems from the Smithsonian


Coasts shelter 70 percent of the world’s people. But they’re under attack from pollution, invasive species, and the steady march of climate change. Smithsonian biologist Andrew Peresta narrates how they protect us, and how ecologists are working to protect them.
