Coral Reefs

Coral reefs rival tropical rainforests as the richest, most diverse ecosystems in the world. Reefs are tropical, shallow water habitats that provide homes for more than one million species of fish, invertebrates and plants. The tiny symbiotic algae that give corals their color, also provide them with energy from photosynthesis and have allowed them to build huge limestone reef structures over a period of many thousands of years. In recent years, coral reefs have come under increasingly severe pressure from a number of sources, including overfishing, dynamiting, soil runoff from deforestation, and bleaching caused by rising ocean water temperatures.
