Water can be broadly separated into salt water and fresh water. Salt water is 97% of all water and is found mostly in our oceans and seas. Fresh water is found in glaciers, lakes, reservoirs, ponds, rivers, streams, wetlands and even groundwater. These freshwater habitats are less than 1% of the world’s total surface area yet house 10% of all known animals and up to 40% of all known fish species. Despite their importance to life as a drinking water source, sustaining crops through irrigation, providing food in the form of fish, powering homes through dams and moving goods by barges –freshwater habitats are disappearing at an alarming rate.
