The Importance of Coral Reefs

Coral reefs are incredibly intricate ecosystems that serve as critical homes for a wide variety of marine life. Many creatures, including fish, marine worms, clams, and many other animals and plants, all play an important role in the coral reef ecosystem as a result of these structures. Nearly a fifth of all marine species are protected and sheltered by coral reefs, which have grown into a vast and intricate ecosystem. The world’s fisheries rely on coral reefs to provide a large supply of protein to the people who live near the reefs. In terms of biodiversity and economic value, coral reef ecosystems rank towards the top of the food chain. They not only benefit local communities, but also the entire planet.

Functions of coral reefs

Aside from reportedly housing the world’s most diversified ecosystems, coral reefs are significant for a variety of other reasons. They:

• safeguard the beaches against the devastation caused by storm surge and tropical storms.

• many marine species with a place to call home.

• marine food networks rely on them for nitrogen and other nutrients.

• help fix carbon and nitrogen

• help with the recycling of nutrients.

Because of this, coral reefs are home to a wide variety of marine life. The following are some of the other reasons why they’re so crucial:

• Coral reefs are critical to the fishing industry because many fish spawn there and juvenile fish spend time there before making their journey to the open ocean.

• Fishing and tourism on Australia’s Great Barrier Reef bring in about $1.55 billion annually.

• For the last million years or so, the study of coral reefs has been crucial in providing a reliable record of climate change. This includes information on recent significant storms as well as changes in coral growth patterns indicative of human impact.

Importance of coral reefs

Coral reefs are a vital part of the ocean’s ecosystem, decreasing the impact of waves on the coast and generating income for countless numbers of people.

• Diverse forms of life abound in coral reefs. One reef is home to tens of thousands of species. The Great Barrier Reef is home to around 400 different kinds of coral, 1,500 different kinds of fish, 4,000 different kinds of mollusks, and six of the world’s seven different kinds of sea turtles.

• It is impossible to locate coral reefs that live in dirty water because coral reefs clean the water they are in. As a result, the ocean water is extremely clear because of the abundance of corals and sponges that feed on ocean particles.

• Over 500 million people around the world rely on reefs for food, employment, and defence against coastal threats. Wave energy can be reduced by up to 97% by coral reef ridges, making them an important barrier against hazards like tsunamis. Marine animals and coastal populations benefit from the protection of mangrove forests and seagrass beds, which serve as nurseries for marine life.

• Asthma, arthritis, cancer, and heart disease have all benefited from the usage of reef-dwelling animal and plant extracts.

• As a result of reefs being damaged or destroyed, coastal towns are at greater risk from both normal wave action and major storms. Coral reefs in the United States are home to millions of people. In order to meet the infrastructure needs of coastal communities and the burgeoning coastal tourism industry, some coastal development is essential.

Types of coral reefs

Coral reefs are found worldwide. Formation, structure, and location varies. It’s:

1. Fringing reefs (Shore reefs): It grows close to the shore and flourish in shallow water.

They’re narrow yet can develop for kilometres along the coast. Fringing corals grow from the coast and spread to the sea. These corals grow uniformly deep till the continental plate ends. As the coral near the beach erodes, bordering lagoons form. Red Sea corals are famed bordering reefs.

2. Barrier reefs: It grows near the end of a continental plate in Australia, Belize, and New Caledonia. They are seldom found along the beach but abundantly inhabited where the sea bed lowers. Barrier reefs evolve slowly into hundreds-metre-wide lagoons. They create lagoons in the Caribbean, Comoros Archipelago, French Polynesia, Indonesia, New Guinea, and Louisiade Archipelago.

3. Platform reefs: These shallow reefs are wider at the top and towards the sea bed. These reefs grow on the continental shelf and are often offshore. They develop from the primary polyp and span several kilometres. Over time, platform reef erosion creates open-ocean lagoons. These reefs grow in atolls based on wind and water flow.

4. Atoll: A circular coral reef with a lagoon. Atolls form over millennia. Atolls originate around small, low-elevation islands, according to scientists.

These islands slowly erode while corals flourish. This forms a coral ring and lagoon.

Pacific and Indian waters have these reefs. The Maldives consists of 26 atolls in the Indian Ocean.

Conclusion

A wider gene pool is provided by a greater variety of species, allowing natural populations to adapt to changing temperatures and environmental situations. Over time, natural selection favours the most effective means of surviving. As a result, species with low genetic diversity face a larger risk of extinction.

Because scientists do not yet know everything there is to know about every species, it is imperative that the ones that now exist be protected. For example, a creature may be vital to an ecosystem, and its removal could have an influence on all organisms in the community. When an ecosystem has a broader variety of species and hence more genetic diversity, the impact of losing a single species is lessened.

Biodiversity is a crucial concern for humanity, and it presents a major challenge to biology in the modern world. Climate change and pollution are the two most significant threats to the Great Barrier Reef’s health and function.
