    Dissolving the Future of Coral Reefs

    Coral reefs, some of the planet’s most beautiful and biodiverse ecosystems, face many natural and anthropogenic threats. Tremendous effort has gone into protecting and rehabilitating these reefs worldwide, but the mounting problem of ocean acidification has the potential to obliterate all progress made by marine scientists, conservationists, and policy-makers thus far.
