Coral reefs are the home to more species than any other marine ecosystem‚ making them some of the most treasured and diverse ecosystems on the planet. They provide revenue for local communities by forming nurseries for fish‚ provide a destination for diving tours and fishing trips‚ break the power of waves to create a buffer that prevents erosion‚ property damage‚ and inundation‚ and protect the wetlands that line the coast‚ as well as ports and harbors. Many medicines are also now being developed

Our coral reefs along our Hawaiian Islands are in danger. The Hawaiian Coral Reefs suffer from degradation‚ which began about 100 years ago from westerners arriving and increasing. We need to do something to prevent our coral reefs from being in harm. They are suffering from oil spills‚ overfishing‚ bleaching‚ and careless tourists. In order for us to make a change‚ we have to research and find for solutions. Our reefs are complex and very diverse to the habitat. They are unique in many ways‚ like

Coral reefs are communities to the sea and home to many living creatures and different types of organisms‚ as well as about one-fourth of the oceans population. Coral reefs are made up of animals called polyps that will remain in one place‚ acting as the main structure of the reef itself‚ these animals have a hard almost skeleton like structure. Scientists who study coral reefs have categorized them into three different types of reefs; Barrier reefs‚ Atolls‚ and Fringing reefs. Coral reefs are put

Coral Bleaching Coral reefs deliver ecosystem services to tourism‚ fisheries and shoreline protection and often called “rainforests of the sea”. Most coral reefs are built from stony corals‚ which in turn consist of polyps that cluster in groups. Coral reefs grow best in warm‚ shallow‚ clear‚ sunny and agitated waters. However‚ coral reefs are fragile ecosystems‚ partly because they are very sensitive to water temperature. They are under threat from climate change‚ oceanic acidification‚ blast

Our most prominent body of coral‚ The Great Barrier Reef‚ is facing annual bleaching within the next twenty years due to warmer‚ more acidic seas. It has alerted scientists all over the world of the future we face and many have come together in hope of conserving this amazing natural wonder and the millions of marine life that

* Coral reefs are underwater structures made from calcium carbonate secreted by corals. Coral reefs are colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals‚ which in turn consist of polyps that cluster in groups. The polyps are like tiny sea anemones‚ to which they are closely related. * Coral reef ecosystems support a variety of human needs. They are important for subsistence‚ fisheries‚ tourism‚ shoreline protection‚ and

Heldt Mr. Bender English 10000 8 May 2012 The Sea After reading The Old Man and the Sea‚ written by Ernest Hemingway‚ I found the most interesting part of the book to be the sea itself.

decreased drastically. Coral reefs are home to more species than all other marine environments‚ and many other species rely on the coral reefs for their own survival. Today coral reefs face multiple threats such as pollution‚ unsuitable fishing practices‚ global climate change‚ and other human activities. If humans don’t take action to conserve and improve the conditions of the oceans the coral reefs will suffer. There are many factors that contribute to the death of coral reefs. One of the major
