Coral reefs are surprising, complicated and important features and structures of the marine environment. Coral reefs are geological formations built from accumulated skeletons of animals and plants that secrete limestone. The intimately linked plant and animal communities that created them are representative of an ecosystem found in the tropical and subtropical waters of oceans and seas across the planet, most commonly in shallow ocean waters near the coast, often close to land. Coral reefs have the highest biodiversity of any marine ecosystem and have provided important ecosystem services and direct economic benefits to large and growing human populations in coastal areas. The natural habitat of coral reefs near the intersection of land, sea and air is diverse and variable and constitutes a potentially stressful and sensitive environment. Coral reef organisms have developed certain adaptations over hundreds of millions of years to cope with recurring disturbances of: damage or destruction, followed by certain rates of recovery and regrowth where the environment can act as a stimulus for the rates of recovery. These are the natural features of the reef's history. However, recent global increases in the destruction and degradation of coral reef ecosystems appear to send a clear message that the speed and nature of recent environmental changes are often outpacing the adaptive capacity of coral reef organisms and communities. Tropical rainforests covered 30 million square kilometers, more than 10 percent of the Earth's land surface. They originally covered at least double that area. The tropical rainforest received 4 to 8 meters of rain per year. This produces dense vegetation that deflects the rain so that the water reaches the center of the paper......the rainforest provides us with a huge amount of oxygen, so destroying it will lead to the end of the human race for us.5 . Coral reefs are a biologically diverse environment. This means that there is a greater variety of species living on coral reefs than any ecosystem anywhere else in the world. Coral reef ecosystems are like vibrant cities, with buildings made of coral and thousands of marine inhabitants coming and going, interacting with each other in a similar way to humans and their daily lives, carrying out their own activities. In this sense, coral reefs are the main metropolises of the sea. Without coral reefs and rainforest, the world would end up in chaos and without its benefits, so spare this old undeveloped tropical rainforest and coral reef from destruction due to development and let these designated areas be a national park with its lively life force.
