Document Summary
Majority of water is found within human body. Earth is called the water planet- mainly salty water. Almost 71% of earth is covered with water. Humans and all other species cannot exist without water. Water rain and ice sculpture the shape of the planet. Water also affects the climate (milder climate seen close to seashore) High concentration of pollutants can affect the biological process of humans: low concentrated will not have a high impact. Quality of the water: what pollutants the water contains or what is dissolved in the water. Therefore, only 2. 6% of fresh water is available for use. A big portion of the 2. 6% is ice caps and glaciers which is also not readily available. Only 0. 014% of freshwater is readily available for use which is mainly found in lakes. The countries under very high water stress are mostly in middle east and northern africa.
