Pitch: This article is written to inform the reader of the issues pose by crown of thorns starfish on coral reefs. The target audience is the general public who may view coral reefs as a tourist destination. There is a need to warn about crown of thorns as research shows that it causes more destruction to corals reefs than bleaching or other disturbances. More details on how these starfish population boomed are given in the article‚ revealing both natural and anthropogenic factors. The article however

Coral reefs and how chemical substances can affect these living organisms is what the research is conducted on. We tend to have a genuine love for coral reefs whenever we view someone’s scuba diving photos. Seeing fishes swim around coral reefs is what many assume is the purpose of the reefs‚ but many do not know their real purpose. However‚ it comes down to learning the importance of coral reefs and how to protect these species that are very much a part of our ocean. This investigation is important

It will then go on to explore the methods of sustainable tourism employed by other nations who are suffering the same problems‚ and judge to what extent‚ and with how much success‚ these methods could be integrated into the Thai system. Tourism is having a major negative environmental impact on coral reefs and the marine life that habituate

Current and Future Status of Coral Reefs in Malaysia Abstract: Coral reefs‚ also known as the rainforest of ocean‚ are the most productive and biologically rich ecosystem on earth (McAllister‚ 1995). Coral reefs are an important source of food and income to millions of people that are living near coast (Burke‚ et al.‚ 2002). There are about 540 species of hard corals that have been identified in Malaysia in total and there are more than 90% of the country’s reefs are situated off the coast of

THE LITERATURE REVIEW Coral reefs have been dubbed the ‘gardens of the sea.’ Burke and Maidens (2004) describe them as both physical structures and complex ecosystems. The physical structure is formed from the secretions of calcium carbonate by tiny marine organisms called coral polyps‚ which forms a shell around them (Mohammed‚ 2007). These shells become cemented together and remain when the reef building polyps die. The basic units of reef growth then are the coral polyps and symbiotic algae

The coral reef structure also buffers shorelines against waves‚ storms‚ and floods‚ helping to prevent loss of life‚ property damage‚ and erosion. Several million people live in U.S. coastal areas adjacent to or near coral reefs‚ and the well-being of their communities and economies is directly dependent on the health of nearby coral reefs. Reefs also protect the highly productive mangrove fisheries and wetlands along the coast‚ as well as ports and harbors and the economies they support. Globally

it. Coral reefs get hit hard by the temperature of the water getting warmer. “Warming of as little as 1°C causes coral bleaching‚ a state in which the tissues of the coral become colorless because of the loss of the zooxanthellae”(Hoegh-Guldberg‚Donner‚pg. 9‚ par 3). This bleaching can stress the reefs and this can effect important functions of the coral. “Moderate bleaching results in stress that causes reduced growth rates and reproductive output‚ whereas severe bleaching results in coral death
