An oil spill is an accidental release or discharge of liquid petroleum hydrocarbon into the environment, often caused by human activity. It can occur in various settings such as on land, waterways, coastlines and oceans. The term refers to both intentional and unintentional releases, but it usually implies that the spill was not intended or desired. Oil spills have severe ecological, economic and social impacts, affecting marine life, wildlife habitats, tourism, fisheries, and human health. They require immediate response and cleanup efforts to mitigate their effects on the environment and prevent long-term damage.
