While coral reefs only cover 0.0025 percent of the oceanic floor, they generate half of Earth's oxygen and absorb nearly one-third of the carbon dioxide generated from burning fossil fuels.
Why are coral reefs important?
Benefits of Coral Reefs. Coral reefs are often called the rainforests of the sea, both due to the vast amount of species they harbor, 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.

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.
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 does connectivity help coral reefs?
But this connectivity could also save coral reefs: if one coral reef is kept healthy and over time adapts to climate change or other stressor, it could spread those better-adapted traits to other coral reefs through the movement of coral larvae. The key is keeping coral reefs healthy in the areas where corals are adapting and in the areas where the adapted corals are settling.
Why do we need to reduce threats to coral reefs?
To ensure people and wildlife can continue relying on the lifesaving services coral reefs provide , we need to reduce threats to reefs.
Why do coral reefs have to be genetically connected?
Because ocean currents tend to follow the same course , one coral reef can be genetically connected to another coral reef hundreds of miles away—one coral reef will provide the baby corals, and the other coral reef will provide the home upon which the larvae settle. When one coral reef becomes too overcome by local stressors, it could affect other coral reefs that are far away.

Why is it important to have a healthy ecosystem?
Importance of healthy ecosystems: Reducing biodiversity through the extinction of species inevitably leads to the breakdown in ecosystem health and function. Healthy ecosystems are essential to provide us with: natural resources, such as foods and drugs.
Why are ecosystems important?
Importance of healthy ecosystems: Reducing biodiversity through the extinction of species inevitably leads to the breakdown in ecosystem health and function. Healthy ecosystems are essential to provide us with: 1 natural resources, such as foods and drugs 2 services we depend upon, such as recycling and purification of water and air, the creation of soil, and the break-down of pollutants 3 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 4 high species diversity.
Why is diversity important for survival?
A diverse range of species provides a larger gene pool, giving natural communities survival options when environmental conditions and climates change. Species evolve over time as natural selection favours the ‘best’ of these survival options.
