What do coral reefs do for people?
Protection from storms: Coral reefs are also our first line of defense against tropical storms, helping to protect all of our coastal communities. Local Economies: Coral reefs support tourism and recreation, drawing people from all over the world to see their beautiful and diverse ecosystems.
What is the economic value of coral reefs?
What is the economic value of coral reefs? Coral reefs support jobs, tourism, and fisheries. In fact, each year coral reefs pump more than $3.4 billion into the U.S. economy And that’s a conservative estimate!
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

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 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.

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.

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.

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.

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.

Study leader Gareth Williams and his team termed this “biophysical decoupling” – the natural links between the biological ( in this case the benthic cover made up of corals and algae) and the physical (temperature, light, productivity and wave energy) becoming disrupted in the presence of human impacts.
Do coral reefs have benthic communities?
Importantly, this research suggests that at populated islands, coral reef benthic communities are not determined by the natural surrounding environment , but by something else: human presence, or at least impacts associated with human presence.
