Coral reefs are one of the main sources of oxygen on the planet, and they produce half of the oxygen in the whole world. Corals are photosynthesizing organisms, meaning they use sunlight to convert carbon dioxide and water into glucose and oxygen. Without coral reefs, oxygen would be limited and humans could not survive on this planet for very long.
Coral reefs are always found underwater, and they primarily thrive in areas near the equator. They require temperatures between 20 and 28 degrees Celsius, and they depend on sunlight, marine animals and other coral reefs around them to survive. Therefore, the coral reefs exist in only one zone of the ocean, the euphotic zone, also known as the sunlight zone. This is the only zone of the ocean where organisms like corals are able to photosynthesize.
Rainforests are often compared to the coral reefs, and the two habitats do indeed share a variety of similarities. The main equivalence of the two is that they are both home to a lot of plants that go through photosynthesis. Other similarities between rainforest and coral reefs include that they both contain an expansive variety of the living creatures on this planet and that they are both endangered due to human actions, and they can only be saved when we all start taking responsibility for the one and only planet we can thrive on.
The coral reefs on our planet are sorted into three categories; the fringing reefs, the barrier reefs and the atolls. A fringing reef is a reef that grows directly from the shore and towards the sea with no water between the sand and the reef at all. These reefs create borders around islands and shores, and boats often destroy them because they are in the shore’s way. Barrier reefs border shorelines a...

...rs, disposing litter properly and much, much more. Cutting down on CO2 emissions causes the climate change and ocean acidification to be reduced. Planting trees, especially mangrove trees, close to the ocean or a river can also help the coral reefs. The mangrove trees absorb water, causing less siltation to happen. Trees also convert carbon dioxide (which causes climate change and ocean acidification) into oxygen, which we need to breathe in. You can also improve the current state of coral reefs by picking up any trash you see lying on the ground or in the ocean. It may not belong to you, but picking it up may save a fish or coral’s life. Spreading awareness to other people also has a significant, positive effect on the coral reefs, since more and more people then start doing all the things listed above, and a lot of small actions are just as good as one big action.
The only difference between a barrier reef and a coral reef is that a barrier reef occurs farther offshore, with a channel or lagoon between it and the shore.
Earth, an endless source of wonder and beauty, produced the Great Barrier Reef. Hustling and bustling, the Reef thrives like a busy city, teeming with life. Sheltering thousands, corals, maintain the well-being of the Reef; however, the world threatens its nature and delicacy. Populations growing and technological advances increasing, the world becomes more and more disconnected with the natural world, posing an alarming risk for the planet we live on. Although many organizations try to keep the oceans clean, because of human interference and unnatural occurrences, the Great Barrier Reef needs scientific help to adapt corals to new conditions for means of survival, putting pressure on the Australian government to save their ocean environment.
This article discusses how important the organisms symbiotic with coral reefs are, as well as how important coral reefs are to our environment. Also explained is how natural and non natural things things like hurricanes and overfishing affects them. A study is quoted about how water acidity also plays a role in the bleaching of corals. Lastly, restoration and conservation efforts are discussed and how we could possibly help our oceans.
Humans have a very large effect on the ecosystems of coral reefs. Sensitivity of coral reefs causes them to be more susceptible to harmful anthropogenic practices. Some of these are sedimentation, global warming, recreational activities, poison fishing, blast fishing practices, water pollution, and coral mining. All of these very different practices can effectively end up with the same results; the mortality of coral reefs around the world. Coral reefs are an important ecosystem of the world, and support many different industries and millions of people.
Spreading the word is the main way to help the reef as only 1 in 10 people know about the coral bleaching and its damaging effects it has on the great barrier reef, the other 9 don’t even know whats going on with the great barrier reef let alone what coral bleaching actually is.
Some ways to help our coral reefs are conserve water: The less water you use, the less runoff and wastewater will pollute our oceans. Help reduce pollution: Walk, bike or ride the bus. Fossil fuel emissions from cars and industry raise lead to ocean warming which causes mass-bleaching of corals and can lead to widespread destruction of reefs. Research what you put on your lawn: Although you may live thousands of miles from a coral reef ecosystem, these products flow into the water system, pollute the ocean, and can harm coral reefs and marine life. Dispose of your trash properly: Don't leave unwanted fishing lines or nets in the water or on the beach. Any kind of litter pollutes the water and can harm the reef and the fish. Support reef-friendly businesses: Ask the fishing, boating, hotel, aquarium, dive or snorkeling operators how they protect the reef. Be sure they care for the living reef ecosystem and ask if the organization responsible is part of a coral reef ecosystem management effort. Plant a tree: Trees reduce runoff into the oceans. You will also contribute to reversing the warming of our planet and the rising temperatures of our oceans. Practice safe and responsible diving and snorkeling: Do not touch the reef or anchor your boat on the reef. Contact with the coral will damage the delicate coral animals, and anchoring on the reef can kill it, so look for sandy bottom or use moorings if available. Volunteer for a coral reef cleanup: You don't live near a coral reef? Then do what many people do with their vacation: visit a coral reef. Spend an afternoon enjoying the beauty of one of the most diverse ecosystems on the Earth. Contact your government representatives: Demand they take action
When you think of the Gulf of Mexico the first thing you don’t think of is coral reefs. You don’t even think of it as place to go surfing. If you ask a surfer what a reef is, they would probably say something that gets in my way while surfing. Reefs being either large or small, have grown for over thousands of years. The build-up of limestone or calcite have given way to magnificent structures that many marine animals call home (Science). Reefs are communities in the ocean where more than hundreds of different ocean species live (Moran). These reefs in the ocean become a community that live alongside each other which allows them to grow. Whether the reef is a place to live, find shelter or a place eat, the reefs of the Gulf of Mexico are truly a wondrous site (Robertson).
All over the world coral reefs play an important part in our environment. Not only are the reefs colorful and beautiful to look at but the coral reefs house several different types of fish and other sea creatures. Coral reefs have started to decline over the years due to “climate change, El Nino events, overfishing, pollution and other pressures” (Newnham 1). A healthy coral reef can also collapse due to a natural disaster (Newnham 2). There can be several different reasons why a coral reef has started to decline or has been destroyed.
Now that corals have been briefly described we can see why the effects of climate change damage coral reef systems. Ocean acidification is one result of climate change. Acidification is caused by an increase of carbon dioxide in our oceans and leads to a decrease in the pH levels of seawaters. This pH decrease reduces the ability of corals to make their hard skeletons. Rates of coral calcification on the Great Barrier Reef and many other reef systems around the world have declined by 15-20% since 1990 due to increasing thermal stress (De’ath 2012). It has already been mentioned that the oceans are absorbing almost all of the excess heat from climate change. This effects coral reef systems in what is known as coral bleaching. The term bleaching refers to the loss of corals’ colors. A coral’s color is the result of the zooxanthellae present. When water becomes too warm the
Located in tropical ocean waters, coral reefs provide priceless resources to both human and marine life. They exist in an area about 30 degrees on either side of the equator. Coral reefs are home to more species than any other marine ecosystem. This includes over 1500 types of fish and 500 different types of algae. (Encarta) However, nearly 60% of coral reefs are in serious danger due to both natural and man-made causes.
Climate change has been affecting coral reefs in a negative way. If the climate continues to get warmer more of our coral reef become bleached, the structure of the reefs will become weak, and algae that keeps coral healthy will die. In the essay, “A framework for understanding Climate change impacts on Coral Reefs” by Joshua Clinner (2016), he emphasizes our climate change has become one of the long-term threats to coral reef. The article “Climate change and human impacts are damaging the world’s coral reefs”, which didn’t include an author (2001), states that the sea temperatures throughout the tropics has increased dramatically leaving much of the coral unhealthy. Spencer Hall (2008), discussed in his article “Coral Reefs and Climate Change”, how the increase in climate change puts a lot of stress on coral reefs because they are very sensitive to the change of temperature. Rigel B (2003) states in his essay, “Climate Change and Coral Reefs”, that coral reef has already been negatively impacted by

Healthy reefs contribute to local economies through tourism. Diving tours, fishing trips, hotels, restaurants, and other businesses based near reef systems provide millions of jobs and contribute billions of dollars all over the world. Recent studies show that millions of people visit coral reefs in the Florida Keys every year. These reefs alone are estimated to have an asset value of $7.6 billion (Johns et al., 2001).
Corals provide shelter for nearly one quarter of all known marine species. The reefs are home to over 4000 species of fish, 700 species of coral, and thousands of other forms of plant and animal life. Living coral reefs are the foundation of marine life, and this also means that they are essential for human life, but all over the world they are dead or dying because people are destroying them at a very fast rate. Already 10% have been lost, and there are predictions that 705 of all corals on the planet will be destroyed in 20 to 40 years unless people stop doing what they are doing now – i.e., pollution, sewage, erosion, cyanide fishing, bad tourism.
These reefs provide a house for many species. If the coral reefs were to become
