6 Reasons Why Coral Reefs are Important
The Great Barrier Reef. Most of us know coral reefs are beautiful, but did you know that they are a vital component of ocean health? In recent decades many of the world’s coral reefs have suffered because of global warming, polluted waters and more direct human harm, such as through unethical overfishing.. Here are six reasons why coral reefs are extremely important to the overall health of ...
What are the benefits of coral reefs?
Benefits from coral reefs can be categorized into 2 types: “direct use values” (fisheries and tourism industry), and “indirect use values” (benefit derived from coastline protection).
Why are reefs important?
Reef structures play an important role as natural breakwaters, which minimize wave impacts from storms such as cyclones, hurricanes or typhoons.
Why are coral reefs called rainforests?
Coral reefs are often called the rainforests of the sea, both due to the vast amount of species they harbour, and to the high productivity they yield . Aside from the hundreds of species of coral, reefs support extraordinary biodiversity and are home to a multitude of different types of fish, invertebrates and sea mammals.
What are the functions of coral reefs?
Coral reefs also sustain to a variety of other functions. They provide shelter to coastlines from the effects of waves and tropical storms. They also provide shelter for many marine organisms. They are an essential source of nitrogen, and other nutrients essential for the function of the ocean's biogeochemical cycles.
Why are reefs important?
Reef structures play an important role as natural breakwaters, which minimize wave impacts from storms such as cyclones, hurricanes or typhoons.
What is the name of the large underwater structure made of coral?
Coral reefs are large underwater structures composed of the skeletons of coral, which are marine invertebrate animals. The coral species that build coral reefs are known as hermatypic or"hard" corals because they extract calcium carbonate from seawater to create a hard, durable exoskeleton that protects their soft, sac-like bodies.
How are coral reefs different from other types of fish?
Majority of the fishes occurring on the coral reefs are small and variously coloured brilliantly. Further, the coral reefs are at the shallower depths than the areas where the commercial fishing is normally done. The over fishing is invariably of the commercial fish varieties and very rarely fishing is attempted at larger scales like trawling, seining, bottom dredging etc., on the reefs. As such, the fishing rarely affects the coral reefs unless it is done by the application of Rotenon, Derris root powder etc., wherein the fishes die in huge numbers totally disturbing the ecology of the coral reefs. I have seen all these personally and in some cases participated in the researches on coral reef fishes.
Why are coral reefs called rainforests?
Coral reefs are often called the rainforests of the sea, both due to the vast amount of species they harbour, and to the high productivity they yield. Aside from the hundreds of species of coral, reefs support extraordinary biodiversity and are home to a multitude of different types of fish, invertebrates and sea mammals. Covering less than one percent of the ocean floor, reefs support an estimated twenty-five percent of all marine life, with over 4,000 species of fish alone. Reefs provide spawning, nursery, refuge and feeding areas for a large variety of organisms, incl
How many different species of coral are there?
There are hundreds of different species of coral, according to the Coral Reef Alliance (CORAL), a nonprofit environmental group. Coral have a dazzling array of shapes and colors, from round, folded brain corals that resemble a human brain to tall, elegant sea whips and sea fans that look like intricate, vibrantly colored trees or plants.
How old are coral reefs?
Most of the substantial coral reefs found today are between 5,000 and 10,000 years old, according to CORAL. These are generally found in warm, clear, shallow waters where there's plenty of sunlight to nurture the algae that the coral rely on for food.
Why are coral reefs important?
Coral reefs are some of the most diverse and valuable ecosystems on Earth. Coral reefs support more species per unit area than any other marine environment , including about 4,000 species of fish, 800 species of hard corals and hundreds of other species. Scientists estimate that there may be millions of undiscovered species of organisms living in and around reefs. This biodiversity is considered key to finding new medicines for the 21st century. Many drugs are now being developed from coral reef animals and plants as possible cures for cancer, arthritis, human bacterial infections, viruses, and other diseases.
How do coral reefs benefit local economies?

Coral reef structures also buffer shorelines against 97 percent of the energy from waves, storms, and floods, helping to prevent loss of life, property damage, ...
How do coral reefs help the economy?
Healthy coral reefs support commercial and subsistence fisheries as well as jobs and businesses through tourism and recreation. Approximately half of all federally managed fisheries depend on coral reefs and related habitats for a portion of their life cycles. The National Marine Fisheries Service estimates the commercial value of U.S. fisheries from coral reefs is over $100 million. Local economies receive billions of dollars from visitors to reefs through diving tours, recreational fishing trips, hotels, restaurants, and other businesses based near reef ecosystems.

Healthy coral reefs contain thousands of fish and invertebrate species found nowhere else on Earth. Learn more and view a larger image. In the 1890s, harvesting sponges was second only to cigar-making in economic importance in the Florida Keys.
What happens when coral reefs are damaged?
Once coral reefs are damaged, they are less able to support the many creatures that inhabit them and the communities near them. When a coral reef supports fewer fish, plants, and animals, it also loses value as a tourist destination.
Why are coral reefs important?
Coral reefs provide protection and shelter for many species of fish and sea life. From the smallest shrimp to the largest predator, sea creatures find both food and protection on coral reefs. Without these important habitats in which to thrive, fish and sea life will cease to exist. Coral reefs protect coasts from strong currents and waves.
How do coral reefs affect the ocean?
Coral’s limestone shell is formed by the ocean’s processing of carbon dioxide. Without coral the amount of carbon dioxide in the ocean rises, which in turn, affects all living things on Earth. Coral reefs are an important food source for humans.
What protects the coast from strong currents and waves?
Coral reefs protect coasts from strong currents and waves.
Why are fish important to humans?
As long as there have been humans, fish have been consumed as a source of protein. The abundance of edible sea life in healthy coral reefs, therefore make them important to human nutrition. Fisheries both large and small depend the coral reef either directly or indirectly, as a source of their livelihood. Tourism.
Do coral reefs exist in murky waters?
Reefs can not exist in murky or polluted waters. Many individual corals and sponges consume particles found in the ocean. In turn, this enhances the clarity and quality of the ocean’s waters. Clean and clear water makes our beaches more beautiful and also allows coral reefs to continue to thrive.
How do coral reefs provide habitat?
However, coral reefs are not just a pretty face. They provide habitats for a huge variety of organisms. Corals themselves are nourished by the algae that colonizes the coral polyps. Photosynthesis by the algae is the process for providing this nourishment; just as plants on land do, the algae consume carbon dioxide and emit oxygen. The earth’s oceans are a huge factor in removing (consuming) carbon dioxide from Earth’s atmosphere, and huge coral reefs such as Australia’s Great Barrier Reef, and Belize’s reefs are important contributors to removing this greenhouse.
Why are corals threatened?
That’s the macro version. Corals are also threatened by agricultural runoff, i.e. the over-fertilization of land crops and livestock effluent. The sea water desalination plants that pump super-saturated salt water back into the ocean. The huge tourist market for tropical shells and corals.
Why are coral reefs important?
Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food, income, and protection. Fishing, diving, and snorkeling on and near reefs add hundreds of millions of dollars to local businesses. The net economic value of the world’s coral reefs is estimated to be nearly tens of billions#N#offsite link#N#of U.S. dollars per year. These ecosystems are culturally important to indigenous people around the world.
What are coral reefs?
coral reefs. marine life. education. Coral reefs are some of the most diverse ecosystems in the world. Coral polyps, the animals primarily responsible for building reefs, can take many forms: large reef building colonies, graceful flowing fans, and even small, solitary organisms. Thousands of species of corals have been discovered;
Why are coral reefs considered the "rainforests of the sea"?
Because of the diversity of life found in the habitats created by corals, reefs are often called the "rainforests of the sea." About 25% of the ocean's fish depend on healthy coral reefs. Fishes and other organisms shelter, find food, reproduce, and rear their young in the many nooks and crannies formed by corals. The Northwest Hawaiian Island coral reefs, which are part of the Papahānaumokuākea National Marine Monument, provide an example of the diversity of life associated with shallow-water reef ecosystems. This area supports more than 7,000 species of fishes, invertebrates, plants, sea turtles, birds, and marine mammals. Deep water reefs or mounds are less well known, but also support a wide array of sea life in a comparatively barren world.

Coral characteristics. Shallow water, reef-building corals have a symbiotic relationship with photosynthetic algae called zooxanthellae, which live in their tissues . The coral provides a protected environment and the compounds zooxanthellae need for photosynthesis.
How can educators use corals to teach about the environment?
Additionally, educators can use corals to teach about conservation and stewardship of the environment. Even if you don't live near a reef, students can learn that they can help protect coral reefs in the United States and around the world. There are many actions, small and large, that everyone can take to help conserve coral reefs.
What are the threats to coral reefs?
Many of these threats can stress corals, leading to coral bleaching and possible death, while others cause physical damage to these delicate ecosystems. During the 2014-2017 coral bleaching event, unusually warm waters (partially associated with a strong El Niño) affected 70% of coral reef ecosystems worldwide.
How much does snorkeling add to the economy?
The net economic value of the world’s coral reefs is estimated to be nearly tens of billions. of U.S. dollars per year. These ecosystems are culturally important to indigenous people around the world.

They’re the most biologically diverse ecosystems in the oceans, and can provide food, jobs, and protection from storms for coastal communities. But reefs around the world are under threat from a variety of a factors including environmental changes, pollution, and overfishing.
How does sea temperature affect coral reefs?
The other ways in which this has impacted are through sea temperature rise and ocean acidification that can really harm coral reef habitats. And so this could be driving coral reefs into coral bleaching, which is a kind of common phenomenon that many people have heard of now, where the coral is bleached.
Why are reefs under threat?
But reefs around the world are under threat from a variety of a factors including environmental changes, pollution, and overfishing. And that could have major implications for communities that rely on these reefs for the seafood that sustains their diet. A new research project is trying to tackle that problem by taking an in-depth look at ...
How will the ocean temperature affect fish?
So one impact that you will see is that as ocean sea temperature rises, fish will move from the equator toward the poles. And so what you see is an enormous decline and reduction in fish catch along the areas of the equator. And it’s predicted to decline by around 50% by 2050 in comparison to what we are seeing today.
Is aquaculture environmentally friendly?
And it can be produced in relatively environmentally friendly ways. So aquacultures span– much like agriculture– spans a wide variety of production systems, species, and techniques. But when it’s done properly, it can be done in a very environmentally healthy way to produce very nutritional products.
Is wild caught seafood better than pork?
CHRIS GOLDEN: As far as I understand from the literature, wild caught seafood and aquaculture across the board, no matter what type and system, is almost always better than pork, beef, and lamb production. I think some types of chicken production can be incredibly environmentally friendly and meet that kind of upper end of seafood production. But really, seafood is a very good form of animal source foods to rely on when done properly.
