NOVA: Reef Rescue

If oceans continue to warm at the current pace, Coral Reefs could be wiped out by century's end. But scientists from around the globe are rushing to help corals adapt to changing climate through assisted evolution. Follow scientists as they attempt to crossbreed heat-resistant corals, and even transplant corals' algae, in a race to save the Coral Reefs from extinction.
