marine pollution
Seas fouled by waste
Marine pollution is the introduction of harmful substances or energy into ocean environments.
It encompasses oil spills, plastic debris, chemical runoff, sewage, and noise pollution that damages ecosystems and wildlife.
Marine pollution from agricultural runoff has created dead zones in coastal waters.
The term often appears in environmental policy and conservation contexts.
