Location: Any pond, lake, or river is included in the fresh water biome.

The top part of the water gets more of the sun's heat and is warm (about 19-25ºC), the middle layer is cooler because it gets less of the sunlight (aobut 8-19ºC) , and the bottom layer, which does not get any sunlight, is cold (about 4-8ºC).

Global warming caused by humans may produce devastating floods and droughts. Humans disrupting the balance of nature in freshwater biomes can harm native animals and plants.

Fresh water biomes provide water for agriculture and most of the drinking water for human populations.

Human activities are significantly impacting and endangering freshwater biomes, which take up one-fifth of the earth's surface. Freshwater biomes are declining worldwide.

About 40 percent of the fish species in the world live in fresh water biomes, and in the past 20 years, freshwater fish populations have declined by over 20 percent. Humans have destroyed habitat for freshwater plants and animals and polluted watersheds. They have filled in crucial wetlands like marshes, swamps and bogs for development.
