Coral reefs support one-quarter of all ocean life, help feed millions of people, and protect homes and cities. Yet, they are threatened by the global effects of climate change. As oceans warm and become more acidic, corals may not be able to adapt fast enough to survive. If reefs disappear, the entire world would feel the impact. Smithsonian scientists have spent years studying coral reefs and thinking creatively about how to save them. Follow them into the field to see why their work is bringing new hope to the future of coral conservation and restoration.
