Coral reefs are an essential component to the ecosystems in Hawaii. Coral reefs are comprised of numerous Cnidarian species that grow sympatrically to form structured colonies. Coral reef colonies support a wide range of marine wildlife. The marine animals utilize coral reefs as their habitat, as a source of food, and as a catalyst for community interactions.
Coral reef communities that are well established are known to be highly biodiverse. Coral reefs are known as the tropical rainforests of the sea. Keystone species of multi-taxa, such as: Echinodermata, Porifera, Chordata, and Arthropoda, all contribute to the complex ecosystem by occupying distinct ecological niches (Jimenez 2012). If the integrity of the coral reef structures is compromised, it impacts the entire ecosystem, and denizens in the community will suffer.
Coral reefs preserve coastline communities. Surrounding reefs are physical barriers that decrease erosive wave action. These coral reef structures provide a buffer from ocean swells, currents and seas storms, protecting beaches from erosion and property from damage.
Coral reefs are not only important for the environment but also beneficial for humans. Reefs provide fish to catch, economic financial gain from tourism and contain medicinal potential (Donner 2007). Fishermen are reliant on coral reef ecosystems, supplying them with an abundance of seafood to market or consume. The economy profits from the revenue generated by the attraction of tourism to the
Coral reefs not only protect coastlines and beaches from wave damage and erosion, but also are the basis for the fishing and tourism industries. Dying reefs is a worldwide problem, and evidence shows that 10% of the entire world’s coral has died, and 60% will die by 2020 if existing conditions continue (NOAA 2000). The reason that the Australian Great Barrier Reef is so important is because not only is it the largest barrier reef in the world, but it is also one of the most evolved models of how to best manage and protect the world’s largest reef system (Ornitz 1996). It extends for 2,340 kilometers (km), covers 345,000 square km and contains 2,900 reefs, 300 coral cays and 600 continental islands (White 1999). Historically, it has been ahead of the rest of the world in terms of recognizing and addressing problems associated with reef degradation.
Coral reefs are the most biodiverse ecosystem on the planet. There are more than 25,000 known species of organisms and countless others that have yet to be identified (Helvarg, 2000). Reefs thrive on the shallow edge of tropical seas, most often on the eastern edge of continents along warm water currents that brush the coasts. Reefs cannot live in cold waters and are limited by ocean depth and available sunlight. Coral is the foundation of the reef community, providing a three-dimensional structure where thousands of species of vertebrates and invertebrates live and feed. Some species of coral are hard, while others soft. Some are branched, yet others are compact and rounded. Coral is made up of large
Consisting of less than 1% of the world oceans, the coral reefs are ancient animals comprising of thin calcium carbonate deposits within the photic layer. Aside from its biologically diverse ecosystems, coral reefs are major source of food for millions and provides habitats and nursery areas for many marine organisms. Coral reefs also act as a physical buffer to protect the coastlines from tropical storms and erosion. In addition, many local communities rely on coral reefs to generate an income through activities such as fishing and diving. However, 75% of the coral reefs are under threat from induced impacts of humans and climate change (Burke, et al., 2011). This essay looks at the human impacts constantly being inflicted on coral reefs.
First, I am going to talk about the importance of coral reefs. Coral reefs are some of the most diverse and valuable ecosystems on Earth. They are home to 4,000 species of fish, 800 species of hard coral, and hundreds of other species. Scientists believe that there are another 1 to 8 million unidentified species (NOAA). According to the National Oceanic and Atmospheric Administration, new drugs are being developed from
Located in tropical ocean waters, coral reefs provide priceless resources to both human and marine
One of the most diverse and biologically rich marine ecosystems is the coral reef. Almost every ecosystem has a greater purpose, coral reef are no exception. For instance they serve as barriers for hurricanes, and other catastrophic storms, their chemicals treat diseases, and one of the most important function is they are a major source of food for humans. But that is just the benefits for humans, they provide shelter and food for numerous organisms, such as fish, turtles, dolphins, and several other marine life.
Finally, there are millions of species who live in the coral reef. It is used both for shelter and for a food supply. There is a vast amount of trawlers that come through each year to dredge the ocean. But think about what would happen if the coral reefs disappear. All the species that depend on the reef for shelter would die. And all the species who hunt for food there would also die. Dredging the ocean rips apart the coral reefs wether that was meant to happen or not. If the natural beauty of the reefs and the security it brings to animals dissapeared, it would be a major
Developing organizations, such as The Ocean Agency and the Coral Restoration Foundation, have been raising concern in efforts to conserve and furthermore sustain aquatic life and the ecosystem in which they inhabit. These unique fish, found living and populating among the coral reef, face a level of degradation and life threatening obstacles. The coral reef acts as a home to more than a quarter of the know fish species, where their population and species have been widely studied. This ecosystem is a beautiful representation of life which supports, and is supported by other neighboring ecosystems; embodying a significance as the leading consumer item for those who live along the reefs. Their importance to our planets collective ecosystem is not fully understood, due to the way these ecosystems are interconnected to one another, but nevertheless illustrates an example of a struggling life which may provide problems for both terrestrial and aquatic life-forms. Aside from the human dependency, being that “More than 450 million people live within 60 kilometers of coral reefs, with the majority directly or
Besides being a spectacle to look at, coral reefs are also one of the most diverse ecosystems on the planet. In addition to ⅓ of all fish (not just species) spend at least a portion of their lives on a reef, they are also home to mollusks, sponges, turtles, and a plethora of different species of coral (Basic Facts, 2014). Coral reefs also can protect coastlines from wave erosion and also help support fisherman that depend on the reef as their livelihood. Contrary to the
Have you ever been to a coral reef if not you will learn about them today.The coral reef biome is one of the most interesting biomes. In this paper you can learn about the climate and location ,the pants and animals,also there environmental concerns and the human impact on the coral reef biome.
One of the main ways that human’s impact coral reefs that could be avoid is coastal development that produces unsustainable tourism. Today, people are constantly looking for tropical places to vacation and adventure on these tropical islands. Since coral reefs can only be supported in tropical waters, they tend to be located by nice beaches on popular islands. The Caribbean is one of the best examples of this. Countries such as Jamaica and the Dominican Republic are generally poor countries with little development. Over the past years, these islands with tropical waters and coral reefs have began to build more and more resorts
“Coral reefs are extremely important for biodiversity, providing a home to over 25% of all marine life. They are also vital for people and business. They provide nurseries for many species of commercially important fish, protection of coastal areas from storm waves, and are a significant attraction for the tourism industry”
The COTS are usually an important part of maintaining the balance of the coral reef ecosystem’s, as it would feed off the faster growing
Coral Reefs are distinctive and unique to the areas around them, boasting a variety and biodiversity of species that can rival any terrestrial area. Although the reefs only cover 0.2 percent of the earth's oceanic floor, an estimated one million species found around coral reefs (NASA)—around 25% of our marine species (Coral Reef Alliance). Beyond science, reefs generate an estimated $375 billion each year (Bunting). Coral reefs benefit the aquarium, fishing, and ecotourism industries, creating at least 500 million jobs (Chasing Coral).
Coral reefs are continuously being both built up and decomposed, so different parts of a reef are in varying stages of succession (Richmond, 1993). Coral reefs are very fragile, because reef-building organisms cannot thrive if the surrounding water changes significantly. Coral reefs require very specific conditions in order to grow: a solid structure for the base; warm and consistent water temperatures (averaging between 20 and 30 degrees Celsius); stable salinity; moderate wave action; and clear water that is low in nutrients and plankton. The water on a healthy coral reef is clear because there are very few nutrients, so plankton that would cloud the water are few. In general corals grow slowly, but they are extremely efficient at living and reproducing in these conditions (American Zoologist, pg 524-536).
