Coral Reefs Essay

Corals build colonies that secrete calcium carbonate to form ocean reefs. When they're healthy, coral reefs provide shelter and food for animals all along the food chain, including the top: us. Across the planet, half a billion people rely, directly and indirectly, on corals for their living. That's why what happens to the 9,000-year-old Great Barrier Reef, as well as to other reefs worldwide, is critical. The floods in Queensland have hurt the Great Barrier Reef by funnelling into the ocean vast plumes of freshwater and agricultural runoff that could severely damage the coral. Besides the extreme rain that sparked the floods, rising ocean temperatures, changes to the ocean's chemistry and the global trade in natural resources — all symptoms of our fossil-fuel economy — are waging a multiform war on the marine

They protect against coastal flooding, wave damage, storm surges, wave damage, and also they provide homes for lots of fish.. Coral reefs are dying because of the increase in ocean acidification that is caused by the increase of CO2 in the atmosphere. Coral reefs may stop growing if the CO2 concentration levels are high which is expected over the coming decades according to the article. Coral reefs are also vital for people and business. In the article it was reported that more than 30 million small-scale fisherman and women depend on coral reefs for their livelihoods, specifically in Indonesia where fish supported by the reefs provide the primary source of protein.

Coral reefs are about 6% of the Great Barrier Reef. However the warmer the air and the water temperature is the more corals it kill. This is a major concern because of the damages it can cause other creatures using corals as a home and protection from predators. Many sea creatures could become extinct if there are no coral reefs.

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

Coral reefs exist globally from 30N to 30S latitude and have existed in some form on Earth for over 200 million years. Over 2500 species of coral have been identified 1000 of which are reef building hard coral. Reefs are actually limestone structures produced by small animals called coral polyps. These polyps contain unicellular plants (algae) called zooxanthellae in their tissue. They have a symbiotic

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.

Coral reefs are wonderful places in the ocean they can be found in shallow water where it is warm and unpolluted. Funny thing is even though they look like plants they are living organisms. There are many kinds like lettuce coral, fire coral, and leather coral. There is also a lot of sea life like cuttlefish, manta ray, and reef whitetip shark. Speaking of sharks, the coral reef is also where many sharks feed.

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

Coral reef ecosystems around the globe are threatened by human interferences and climate change. This has led to many scientists conducting studies on global coral reef ecosystems to gain a better understanding of the cause and effects of coral reef damage. In both Hodgson’s (1999) and Carpenter et al.’s (2008) studies, they are aware of the continuous degradation of global coral reef ecosystems. Hodgson's study involved conducting a survey on global coral reef ecosystems to see whether human actions were affecting the health of supposed pristine Coral reefs. Carpenter et al. incorporated Hodgson’s study into a compiled study about the possible extinction of reef building corals due to climate change and anthropogenic effects. Carpenter’s

Coral reefs are threatened by global warming. They can only live in waters between 18 C and 30 C. Therefore, with the increase in temperature of the surrounding water, there has been an unprecedented increase in the number of coral bleaching events during the past 2 decades (which have had some of the warmest years in history). When ocean temperatures get too high, coral polyps lose the symbiotic algae inside them, causing them to turn white, or "bleach," and eventually die.

Coral reefs are indispensable to multiple life forms, particularly human beings. In response to concerns, many environmental

The deterioration of coral reefs is mainly linked to human activities – 88% of coral reefs are threatened through various reasons as

     Coral reefs are one of the oldest types of living systems on earth, and certainly one of the most spectacular (Goreau, 1987). They are massive underwater structures formed by the limestone skeletons of tiny invertebrate animals. Reefs house a greater diversity of body forms, chemistry, and animal phyla (thirty-two compared to the eight that inhabit the most biodiversity ecosystems on land). Phyla comprise the second largest category of living things, after kingdoms.
