Human activities threaten marine habitats at the ocean's edge.
This thin line of life needs our care Healthy coastal wetlands are a fertile birthplace and nursery for fish and shellfish. When we destroy coastal wetlands, we destroy the source of much of the fish we eat. More houses along the coast mean more water pollution. As our numbers grow, it becomes more and more important for us to take care of our coastal environment. Only then will the sea continue to feed us.
