Wasser

Water is one of the most versatile elements on earth. Its ability to assume three states of aggregation guarantee the water cycle that makes life possible, as it happens on our planet. The constant cycle of evaporation and rain ensures that fresh water is theoretically always available. But the resulting inexhaustibility is endangered, because people increasingly intervene in this cycle through pollution and remodeling of entire landscapes and change the habitats that are shaped by water, which ultimately threatens the existence of mankind.
