This would jeopardize the lives of many types of crabs, mussels, and sea snails that live in tidal zones and disrupt the diets of larger animals who rely on them for food, threatening
entire coastal ecosystems in the process.
Topsoil and natural vegetation would ordinarily filter many of these pollutants out, but the impermeable pavement that covers much of the surface where these pollutants originate carries it right into storm drains and into streams, rivers, lakes and the ocean where it can poison marine life — which we might eat — as well as
entire riparian or
coastal ecosystems.
