How are coral reefs and mangroves being threatened, and how is this destruction linked to other environmental problems?
What will be an ideal response?
Coral reefs are being threatened by bleaching (caused by increases in ocean temperature) and exploitation of reefs for fish, shellfish, and other sea life, in addition to tropical fish harvesting. Mangroves are being threatened by logging, coastal land development, and the development of shrimp ponds. The destruction of coral reefs and mangroves are linked to global climate change and the overexploitation of resources.
