Approximately half of all federally managed fisheries depend on coral reefs and related habitats for a portion of their life cycles. 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, and erosion.
Despite their great economic and recreational value, coral reefs are severely threatened by pollution, disease, and habitat destruction. When a coral reef supports fewer fish, plants, and animals, it also loses value as a tourist destination.
The Great Barrier Rearmost 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.
From the smallest shrimp to the largest predator, sea creatures find both food and protection on coral reefs. Without coral the amount of carbon dioxide in the ocean rises, which in turn, affects all living things on Earth.
The abundance of edible sea life in healthy coral reefs, therefore make them important to human nutrition. Fisheries both large and small depend on the coral reef either directly or indirectly, as a source of their livelihood.
Coral reefs are vital to the tourism industries, creating and protecting many of the world’s most beautiful beaches. Without clear waters and opportunities for recreational exploring through diving and snorkeling, tourist dependent economies collapse.

These gorgeous undersea cities are home to thousands of individual organisms, including fish, crustaceans, corals, anemones, and microorganisms.
Coral reefs protect coastlines from the damaging effects of waves and tropical storms. Coral reefs help with nutrient recycling, assist in carbon and nitrogen-fixing, water filtration, and provide nitrogen and essential nutrients for the diverse array of life that exists within the marine food chain.
Eels, octopuses, clams, crabs, and clownfish rely on the reefs for protection. According to the , baseline data from 2011 indicated that the global demand for seafood destined for human consumption is 143.8 million tons per year.
Coral reefs stabilize mangroves and seagrass beds, providing habitats, oxygen, and vegetation for inland species besides humans. According to Reef Relief, there is a reason that coral reefs don’t really exist in murky or polluted waters.
Corals and sponges are often filter feeders, which consume particles from the water that surrounds them. The problem is, the oceans today are much dirtier than they were when these simple organisms first evolved to perform this essential task.
The amount of plastic, microplastics, toxins, and chemicals in our oceans is too much for the simple corals to take. They take in these toxins and exhale clean water, but the process corrupts their bodies as surely as it would our own.
Without coral to filter the water and clean it up, our beaches and reefs will continue to succumb to pollution. Coral reefs are usually part of national parks, and tourism accounts for a huge chunk of the economy in some places.
Hawaii, Australia, Florida, and so many other places rely on their beaches, reefs, and wildlife to draw in visitors and keep themselves afloat. Pollution and coral damage has caused water to become murkier, beaches to become less hospitable, and many marine animals to become endangered.
However, coral ecosystems face serious threats, mainly from the effects of global climate change, unsustainable fishing and land-based pollution. Fish, corals, lobsters, clams, seahorses, sponges and sea turtles are only a few of the thousands of creatures that rely on reefs for their survival.
Many of the world’s reefs have already been destroyed or severely damaged by pollution, unsustainable fishing practices, disease, global climate change, ship groundings and other impacts. Healthy coral reefs are among Earth’s most biologically diverse and economically valuable ecosystems and are vital around the world.
Fish, corals, lobsters, clams, seahorses, sponges and sea turtles are only a few of the thousands of creatures that rely on reefs for their survival, but so do humans. Coral ecosystems are a source of food for millions; protect coastlines from storms and erosion; provide habitat, spawning and nursery grounds for economically important fish species; provide jobs and income to local economies from fishing, recreation, and tourism; are a source of new medicines; have cultural significance; and are hotspots of marine biodiversity.
The continued decline and loss of coral reef ecosystems will have significant social, cultural, economic and ecological impacts on people and communities in the U.S. and around the world. NOAA is working to understand and address key threats to coral reef ecosystems: the impacts from global climate change, unsustainable fishing practices and pollution.
Additionally, increased carbon dioxide in the atmosphere changes ocean chemistry and harms reef-building corals. The effects of land-based sources of pollution, such as coastal development and agricultural runoff, can impede coral growth and reproduction, disturb ecological function and cause disease.
Our work takes into account the inextricable connections coral reefs have to the lands they surround and the communities and economies they support. Divers inject the central disk near an arm of each starfish with ox bile, a natural substance that kills the creature, but does no harm to the reef.
From coral mapping, monitoring and modeling to on-the-ground and in-water restoration activities, NOAA is leading ridge-to-reef efforts to support the management and conservation of these valuable ecosystems. Protect coastlines from the damaging effects of wave action and tropical storms provide habitats and shelter for many marine organisms are the source of nitrogen and other essential nutrients for marine food chains assist in carbon and nitrogen fixing help with nutrient recycling.
Natural resources, such as foods and drugs services we depend upon, such as recycling and purification of water and air, the creation of soil, and the break-down of pollutants social, cultural and recreational activities, such as those found in our many unique National Parks, World Heritage Areas and the other special places we like to visit high species diversity. A diverse range of species provides a larger gene pool, giving natural communities survival options when environmental conditions and climates change.
A species may play a crucial role in an ecosystem and if it is removed, all organisms in that community may feel the impact. The health, management and conservation of biodiversity, is a fundamental issue facing humankind, presenting a real challenge to biology today.
The major factors that affect the health and function of our Great Barrier Reef are climate change and pollution. Over 850 million people, which amount to about an eighth of the population, depend on marine life.
Some local threats include coastal development, overfishing, and releasing untreated sewage to streams. Funding grassroots projects to protect this valuable ecosystem is therefore very vital to ensure that the coastal populations enjoy the benefits of reefs.
Coral reefs harbor a diversity of marine life, and that is why they are referred to as the “rainforest of the sea.” Organisms and different types of fishes find food and shelter from the reefs. Many of these coral lives produce defensive chemical compounds, especially those that move slowly.
Fish that accumulate on coral reels provide an excellent food source for billions of people in the world. Marine life promotes the local economy by increasing the number of tourists in coastal regions.
According to research, there is scientific evidence that shows the atmosphere and oceans are warming due to the greenhouse effect. This rise in temperature leads to the bleaching of the reefs, which cause outbreaks of diseases within the coastal lines.
Furthermore, the amount of carbon dioxide being absorbed in the ocean has significantly reduced the calcification rates required for reef-building. As a result, the normal circulation of water is affected, and this influences the ecosystem dramatically.
One way to protect these valuable resources is by practicing safety measures while visiting these areas. Other ways to reduce effects to seas include reduction of stormwater runoff, using environmentally safe modes of transport, being on the lookout when acquiring marine or aquarium fish among other practices.
Over 75% of the reefs in the world are currently under threat due to climate change and severe human activities. Carbon is another threat to coral reefs due to the increase in gas emissions to the atmosphere.
The extinction of coral reefs depends on human practices and whether climate change will still be a problem in the future. Reefs are resilient by nature, and this means that they can be recovered if favorable conditions are created.
If you live close to the ocean, several practices can help protect these valuable resources. Fishers should avoid hunting for rare species or juveniles living within the reefs for future sustenance.
Taking care of them ensures that we’ll keep getting food and inspiration to people all over the world and improve the livelihoods of those living within the local areas.
