Folks get ready for a snorkel near Cano Island in Costa Rica. See other beautiful phenomena from Costa Rica.
There is no doubt that coral reefs are spectacular parts of our planets vast oceans. They are filled with vibrant colors and a wide variety of marine life forms. But if current trends continue, we will not be able to enjoy these sights much longer. "For example, the results of the first global survey of human impact on coral reefs involved 250 corals and 30 countries around the world. The surveys revieled no pristine reefs; in almost every case there were visable signs of human impacts (Hatziolos 4)." Some of these reefs were totally void of high valued species of coral. Were fishing for sharks, lobster, giant clam, and grouper was present there was evidence of "cyanide and blast fishing (Hatziolos 4)." Much of the reefs species are valuable and much of them are harvested relentlessly. These are not the only problems that modern coral reefs are experiencing. Much of the reef populations are enduring hardships due to polution resulting in less successful populations. If these problems and more continue at there current rates, our grandchildrem may not have these wonderful reefs to experience.
Biology of coral reefs:
- life cycles
- energy concumption
- current status of coral reefs
Economic opportunities of coral reefs:
- fishing industry
Human impacts on coral reefs:
- over eploitation
- over fishing of target species
- effects of coastal development
- distructive fishing practices
- cyanide fishing
- inland pollution and erosion
- marine pollution
What is being done?
- Eductating people about problems
- environmental organizations
- government intervention
