Indian Ocean/ Coral Reefs

The Indian Ocean is large and biologically diverse, but the corals there face great dangers. They also face enormous overall pressure from population increases and illegal fishing methods like dynamite blast fishing and cyanide fishing. And, sediment runoff from agriculture has been a problem region-wide, smothering corals offshore. The United Nations Environment Program estimated that 20 percent of the region's coral reefs had already been destroyed—and that was in 1984. So if we keep doing what we're doing right now, more coral reef's will be destroyed.
A Reefwatch diver surveyed corals in the Seychelles, where reefs suffer the characteristic Indian Ocean impacts of mining and farm runoff.
It's all because of US.
