Water is the basis for the entire biosphere. Ponds, rivers, lakes, wetlands, and oceans are the habitat for myriad plants and animals and are a key component of the ecosystem. Groundwater is at once our main source of drinking water and a habitat. We use water for our food, daily hygiene, and recreational activities.
