Ensuring that these ecosystems stay healthy is getting harder, as the oceans absorb excess carbon dioxide and overfishing escalates, aided by advances in deep-water fishing technology. Carbon dioxide turns the water more acidic, threatening the survival of shellfish. Hundreds of marine species are now endangered, and populations of large predatory fish are dropping. A new satellite-driven interactive tool called Global Fishing Watch will enable governments to track tens of thousands of fishing vessels worldwide and detect illegal fishing.
