Life is water and the basis of life is water. Clean water is of vital importance. The world’s supply of fresh water is becoming increasingly scarce, so it is important to manage water economically and responsibly. Water scarcity is the result of many complex interacting human and ecological factors. In the first instance, climate change is a considerable cause. Climate change leads to water sources drying up, but also to rising sea levels, which causes floods. This affects the availability and quality of water.
