Storyline: Fresh Water
Although merely 3% of water on earth, fresh water plays an important part in the planet's weather and erosion. It is immensely important for all non-marine wildlife, which drinks fresh water and swims, procreates, hunts in it. Its concentrations, such as rivers, lakes and swamps, abound in aquatic and other species, often adapted to 'wet' life.
