Although critical to natural and human communities, fresh water is threatened by a myriad of forces including overdevelopment, polluted runoff and global warming. Human activities near freshwater habitats can cause pollution and harm to species. Several key areas of human impact on river ecosystems are: pollution; flow modifications; exotic species; harvesting. Human impact.

The effects of each stage of the forestry cycle – ground preparation, tree planting to canopy closure, the maturing crop and felling – may have an impact on local freshwater. One way to meet the freshwater needs of both people and ecosystems is to practice water conservation. Fresh water biomes provide water for agriculture and most of the drinking water for human populations. Pollution is difficult to control because it is often the result of human infrastructure around a river. Drought impacts on freshwater ecosystems can affect water supply for human consumption, fish and invertebrate populations, and agricultural practices (Larsen, 2000; Ramírez et al., 2018) Negative impacts on freshwater ecosystems, including reduction in water quality and frequency of flood events, can alter important habitat for fish and invertebrate species. Air Quality . People withdrawing water from freshwater biomes cause them to shrink and degrade plant and animal habitats. COVID-19 is an emerging, rapidly evolving situation.
