	EPA - Freshwater Ecosystems
		Freshwater ecosystems are aquatic systems which contain drinkable water or water of almost no salt content.
		Freshwater resources include lakes and ponds, rivers and streams, reservoirs, wetlands, and groundwater.
		Despite all of their value and importance, many freshwater ecosystems are being severely damaged by human activities.

	Integrating Freshwater Ecosystem Function and Services with Water Development Projects
		These engineered systems are generally optimized solely for the purposes for which they were created, but it is now necessary to optimize them with respect to conservation and enhancement of freshwater ecosystems in addition to their historical goals.
		Of particular importance are long-term effects of water projects on the amount and routing of water and waterborne materials along the flow path to the ocean as well as maintenance of sufficient habitat for the persistence of species with their natural genetic variability (Naiman et al., 1995).
		It is hard to protect what we don't understand, and for this reason Section II presents a brief discussion of biodiversity in the context of freshwater ecosystems, including a short description of those ecosystems.

	Where The Nature Conservancy Works - Where The Nature Conservancy Works - Protecting nature, preserving life
		Freshwater ecosystems — including rivers, lakes, and wetlands — provide virtually all of the easily accessible drinking water on the planet, and support a wide variety of other species, including fish and other aquatic organisms, wildlife and plants.
		Islands often have unique and fragile ecosystems and house many rare species, which means global environmental problems can hit them first and hardest.
		The Nature Conservancy works with many island programs around the world, to help build and stabilize their conservation efforts.

	Student Conference on Human Rights 2005 - Cyberschoolbus United Nations
		Besides the harmful health effects of pollution, damages to the ocean’s ecosystem negatively impacts the fishing industry and tourism and therefore the livelihood of those reliant upon these trades.
		In 2000, the World Commission on Dams (WCD) released a report analyzing 125 of the world’s largest dams in terms of their outputs and the measurable impacts the have had.
		The report found that two-thirds of ecosystem impacts had negative consequences with impedance of migratory fish ranking as the most significant for twenty-five percent of the dams investigated.
