Coral reefs.

Extracts from this document...


Introduction Coral reefs are some of the oldest ecosystems on earth, they are built by a variety of coral and other species that cover skeletons of calcium carbonate that build up over time. Corals are live animals made up of a group of polyps. Each polyp makes a skeleton for protection and support. It then joins its skeleton to those of the polyps around it. So, because of this, the individual skeletons of hundreds of coral polyps live as one coral settlement. Polyps are always creating new skeletons at their bottom and sides. As this happens they expand upwards and outwards from the coral centre. They grow on top of the old skeletons, which have died. New polyps can be created. So because of this happening, most of the structure of a single group of coral and of the larger coral reef comprised of many coral colonies, is made up of dead skeleton material. ...read more.


Why is coral so important for the environment & why does it need protecting? Besides their environmental value, coral reefs are a big money maker for the near by towns, they are of social and cultural importance to the countries they surround. Many islands are formed exclusively from coral materials, and owe their very existence to their coral reefs. These include the 80 atolls in French Polynesia, as well as many coral islands scattered over the Indian Ocean. Coral reefs are of crucial importance as natural barriers protecting shorelines from destructive storms and waves, especially in cyclone areas Coral reefs are the main source of food for countless island inhabitants: 90 % of all animal protein consumed in most of the pacific island is from marine species With some of the most spectacular marine landscapes in the world, coral reefs are an invaluable asset to local tourism and leisure industries Conclusion Palau could exploit the reef and allow tourist in with total disregard to ...read more.

Ban diving and swimming in the area, or make guided tours, which will show the public the coral, whilst being led by an expert. 2. Ban fishing in the area, and also make permits for fishing harder to achieve, or make a fine for fishing. 3. Set up an organization to help stop the cutting down of the mangrove trees. 4. Make a speed limit, and have a certain area for water sports, which is away from the coral. 5. Use better piping, and pumps the sewage elsewhere in the ocean. 6. Not let ship within a certain area of the coral, or put up a barrier. Sustainable development is the best way to solve everyone's problems. It allows Palau to make money and make sure the reef is healthy. ...read more.
