Effects of Oil Spills on Humans

Direct exposure of oil workers, air contamination, skin absorption, impact on fisheries, property value reduction, and job losses for fishermen and ship workers.

Effects of Oil Spills on Wildlife

Clogging blowholes, disrupting communication of marine mammals; coating rocks and sand; damaging plants; and making habitats unsuitable for wildlife.
