Reefs are very fragile underwater ecosystems and environments that cannot tolerate a wide range of conditions. Turbidity, temperature, and water depth are variables that must be firmly controlled in order to support healthy reefs. Other potential problems can be attributed to human activities. The major obstacles are chemical and organic pollution, thermal pollution, turbidity, and physical destruction.
The general trend is that reefs tend to be most protected along the coasts of developed countries and are in serious jeopardy in developing countries. Many may be asking about the value of coral reefs. The Coral Reef Destruction is due to the first things that come to the human mind are:
Their protection of nearby coastal areas, much like that afforded by barrier islands
Therefore, the abundant fishery that they support for both sport and commercial fishing.
The tourist and their recreational values.
The position of the most prolific and diverse biotic systems in the marine environment, and as such deserving of protection.
