Oil spill presentation
This document discusses the causes and effects of oil spills on the environment. It begins by defining an oil spill as the release of liquid petroleum into the environment, particularly marine ecosystems, due to human activity. Common causes of oil spills include equipment failures, natural disasters, deliberate acts, and illegal dumping. The effects of oil spills include damage to local industries like tourism and fishing, negative human health impacts, and harm to marine life and ecosystems. Cleanup methods discussed include bioremediation, mechanical removal, burning, skimming, and using sorbents to contain spills. The document concludes by emphasizing the role of human error in many oil spills and highlighting prevention and containment techniques.
