text:  Marine trash is a health and safety concern for humans, too. Children playing on beaches can step on shards of glass or metal. Boaters can be left stranded if the engine sucks up a nylon net and dies. And let's not forget the environment. Marine debris and pollutants can be incredibly long-lasting, causing permanent damage to coral reefs and other fragile habitats. If you want to help, consider participating in the International Coastal Cleanup.
