Global Degradation of Coral Reefs - Essay ExampleCoral reefs ar productive ecosystem and diverse habitats in the world because of their economic and social importance including food for thought provision, tourism among others. at that place is a last rate of global degradation of chromatic reefs and these calls for their sustainable management. Their diminution has fueled the topical anesthetic and international communities to come up with approaches of monitor coral reefs. Ecology involves the study of organisms in the environmental environment which require spatially accurate data given the distribution of spices. In the past manual and business line observation methods were used to gather ecological information. These methods were labour intensive and time consuming. As a result, upstage sensing became widely incorporated in the ecological duties because of its large coverage, cost effectiveness and accuracy. This called for the venture into newfangled technologies to e nable easy and faster access of remote sensed information in the management and monitoring of ecological species. (Knight, D., E. LeDrew, et al. 1997). Coral ecosystem is one of the important habitats in the world. Coral reefs play a significant utilization in checking the amount of carbon dioxide in the sea. Without them regulating the level carbon dioxide in water could be difficult and many species on earth including human being could be at a high risk. Although, that is the current situation in the world because people have destroyed the reefs due to the level of impurities in the water bodies this has resulted in global warming. They are also a habitat to millions of fish species, source of employment, food provision, tourism attraction sites and protect the shores fro waves. In short they are source of livelihood to millions of people almost the globe (Goodman, J. A., M. Velez-Reyes, et al. 2006).This paper addresses landscape remote sensing approaches of mapping coral reefs .DiscussionBy 2100 coral reefs will be degraded if no measures are taken. They only cover 2 percent of the centre ocean area and annually they provide a home for almost 33 percent of thousands on marine species. As mentioned above, coral reefs are threatened by a number of factors. For example, coral diseases resulting from dilapidation the reefs, coral reefs can be in danger of water related coastal development as it is in the case in the Caribbean. (Gledhill, D. K., R. Wanninkhof, et al. 2008). As a result of a variety of biological species in the coral ecosystem, over fishing can also be harmful because they interact and depend on one another for food and competition. Harvesting of coral reefs can be classified into controllable, Malthusian-over fished and poisonus.Studies show that reduction of species in the coral ecosystem can lead to prolification of algae. (Manus, J. W., L. A. B. Menez, et al. 1999).In response to this damage a 5 year bulge out was launched and it was fun ded by the centre for sponsored coastal ocean enquiry (CSCOR).The research key provisions were to provide adapted data on coral reefs, tool and approaches to help marine scientists and identify phenomena that caused the degradation of coral reefs. The research addressed four major areas namely interaction between water related activities and coral reefs, causes of biological pressure, assessment of marine protected areas and the overall nature of coral ecosystem (Hallock, P., B. H. Lidz, et al. 2003). Researchers
