Marine debris includes all objects found in the world’s marine and coastal environments that do not naturally occur there. Marine debris is found in every marine and coastal environment in the world, and is more than just an eyesore. Marine debris annually kills thousands of marine animals and seabirds who wrongfully ingest harmful substances or become entangled. Marine debris can also be potentially hazardous to human health, close beaches, or provide safety risks at sea. Every year thousands of tons of marine debris are collected in a world-wide coastal clean-up effort. PCCS naturalists and educators will give a brief introduction to this ocean plague and let visitors know what steps they can take to alleviate this growing problem. Dates and times will be announced in the spring of 2011.
