Seagrass Seagrass is the only flowering plant that lives completely submerged in coastal waters. Seagrass meadows are popular nursery grounds for many fish species, crustaceans, and other organisms. Rising sea and carbon dioxide levels are making seagrasses vulnerable to extinction. If seagrasses continue to face such risks due to global warming, then organisms that depend on them for food such as sea turtles, manatees, dugongs, seabirds, sea urchins, and others, will also come under threat.

● ● Areas in the oceans and seas with very low oxygen to support life are called “dead zones.” The rise in temperatures has increased the number of dead zones. ● ● Phytoplankton produce half of the oxygen that the world breathes. Climate Facts
