Seahorses Threatened by Trawling and Pollution

Seahorse populations in several parts of the world, including in the Chesapeake Bay, are threatened in part because of the destruction of underwater grasses that seahorses need as shelter.

Amanda Vincent, a zoologist and seahorse expert at the International Union for the Conservation of Nature, argues that governments around the world can help save seahorses by ending bottom trawling for shrimp (which rips up seagrasses) and reducing water pollution (which blocks light that grasses need to grow).
