How are pollution and overdevelopment along the world's coastlines reducing the amount and quality of fish in marine fisheries?
What will be an ideal response?
Answer: Marine animals rely on coastal wetlands, mangrove swamps, or rivers for spawning grounds, but the world's wetlands and coasts are being destroyed by pollution and overdevelopment. The massive 2010 oil spill in the Gulf of Mexico will have long-term consequences for aquatic life in an area that previously supplied 20% of all U.S. catch. About one-half of the world's population lives within 200 kilometers (124 miles) of an ocean, contributing to the pollution that reaches the seas. Heavy metals such as mercury have contaminated fish and damaged the health of people who eat them. Sewage, fertilizers, and runoff from agriculture have overfed algae (tiny marine plants), causing them to grow so rapidly that they use up the oxygen that fish need to breathe. In turn, the collapse of oceanic food supplies puts greater pressure on inland, freshwater species.
