However, ecological issues are just the beginning According to the World Resources Institute"Freshwater ecosystems — the diverse communities found in lakes, rivers, and wetlands — may be the most endangered of all. Freshwater ecosystems have lost a greater proportion of their species and habitat than ecosystems on land or in the oceans; in addition, they are probably in greater danger of further losses from dams, pollution, overfishing, and other threats.
