Problems Affecting Freshwater Biomes
As with any biome, freshwater biomes have problems that are affecting them. One of these problems is the building of dams. When dams are built fish are barricaded when they try to travel in order to reproduce. No reproduction obviously leads to the extinction of species. Over fishing is another problem that can cause some species to become extinct. Pollution is a third problem affecting the freshwater biome. The dumping of garbage, factory fumes, and run-off from farms are all things that can pollute the freshwater biome. When the water becomes polluted the populations of plants and animals can be affected. Too much phosphorus from fertilizes (found in run-off from farms) can also promote excessive algae growth which can choke off the other organisms in a body of freshwater such as a lake or pond. Global warming is also affecting the freshwater biome. Higher temperatures are causing the water to be evaporated more quickly and because of this plants in or around the source of water are dying and animals are losing their food sources.
