Water and the future of life on earth | DW Documentary

change is altering the precipitation cycle. Groundwater levels are falling. If humans don’t change course, water shortage could end life as we know it. 
"Clearly we’ve messed up the show. Nature will always be here however. And nature can and will restore these ecosystems. The only question is, will we help her do that? Or will she do it by herself, after we are gone?" Water is the foundation and the source of life. 

Water governs the subtle interactions of the Blue Planet’s ecosystem and its climate. It is a miracle. But by overusing water resources, the human species risks wiping itself out. Fresh water in particular is key for life on earth, but supplies are less plentiful than one might think. The increasing destruction of large areas of land is causing groundwater supplies to dwindle. Human intervention is undermining the most valuable and vital of all resources. 

Water plays a significant role in the climate. As temperatures rise and the atmosphere warms, evaporating water acts as a greenhouse gas, fuelling the spiral of climate change. Scientists are trying to devise methods of using water to cool the atmosphere to reverse the trend. This documentary sheds light on the careless use of water, a finite resource we take for granted but without which life on earth isn’t possible.
