Aquatic Ecosystem Biodiversity, Ecology and Conservation

The total water resources of the earth equal to 326 million cubic mile; only 2–5 % of water is fresh water, 97.5 % is salt water. Almost 69 % of fresh water resources are tied in glaciers and ice caps, about 30 % is ground water and a mere 0.27 % is surface water. Water resources are important for the survival of the planet. Aquatic biodiversity is one of the most essential characteristic of the aquatic ecosystem for maintaining its stability and means of coping with any environmental changes.
