Damage on coral reefs

Are the present conservation efforts sufficient?

1. Support reef-friendly businesses. Ask what your dive shop, boating store, tour operators, hotel and other coastal businesses are doing to save the coral reefs. This is especially important in coastal areas with reefs. Let them know you are an informed consumer and care about reefs.
2. Don’t use chemically enhanced pesticides and fertilizers. Although you may live thousands of miles from a coral reef ecosystem, these products end up in the watershed and may ultimately impact the waters that support coral.
3. Volunteer for a reef cleanup. You don’t live near a coral reef? Then do what many people do with their vacation: visit a coral reef. Spend an afternoon enjoying the beauty of one of the world’s treasures while helping to preserve it for future generations.
4. Learn more about coral reefs. How many different species live in reefs? What new medicines have been discovered in reef organisms. Participate in training or educational programs that focus on reef ecology. When you further your own education, you can help others understand the fragility and value of the world’s coral reefs.

5. Become a member of your local aquarium or zoo. Ask what they are doing and what your donation can do toward saving the world’s coral reefs. The answer may pleasantly surprise you.
 What are pressures faced by coral reefs?

Healthy coral reefs are among the most biologically diverse and economically valuable ecosystems on earth, providing valuable and vital ecosystem services. 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, and are hotspots of marine biodiversity. They also are of great cultural importance in many regions around the world, particularly Polynesia.
What makes coral reefs valuable?
Biodiversity: Coral reefs are essential spawning, nursery, breeding, and feeding grounds for numerous organisms. In terms of biodiversity, the variety of species living on a coral reef is greater than in any other shallow-water marine ecosystems and is one of the most diverse on the planet, yet coral reefs cover less than one tenth of one percent of the ocean floor. Coral reefs support more than 800 hard coral species and more than 4,000 species of fish.
 
Coastal Protection: Healthy coral reefs have rough surfaces and complex structures that dissipate much of the force of incoming waves; this buffers shorelines from currents, waves, and storms, helping to prevent loss of life, property damage, and erosion.  Coastlines protected by reefs are more stable, in terms of erosion, and are also a source of sand in natural beach replenishment

What should be done to conserve the coral reef ecosystem?
  1. Conserve water: The less water you use, the less runoff and wastewater will pollute our oceans.
  2. Help reduce pollution: Walk, bike or ride the bus. Fossil fuel emissions from cars and industry raise lead to ocean warming which causes mass-bleaching of corals and can lead to widespread destruction of reefs.
  3. Use only ecological or organic fertilizers: Although you may live thousands of miles from a coral reef ecosystem, these products flow into the water system, pollute the ocean, and can harm coral reefs and marine life.
  4. Dispose of your trash properly: Don't leave unwanted fishing lines or nets in the water or on the beach. Any kind of litter pollutes the water and can harm the reef and the fish.
  5. Support reef-friendly businesses: Ask the fishing, boating, hotel, aquarium, dive or snorkeling operators how they protect the reef. Be sure they care for the living reef ecosystem and ask if the organization responsible is part of a coral reef ecosystem management effort.
