Water goes into a cycle and what we do today with it will come back to us!

In the past century water policies relied on the construction of massive dams and pipelines. While investment in these facilities can increase the freshwater supply and provide water for billions of people the construction of dams have serious social, economical, and ecological costs. Some implications of the use of dams are modification of the water quality, increased waterborne parasitic diseases, and reduction of fish yields downstream. Another issue is that people need to be replaced, to build new dams. Also dams are build where animal used to live and trees used to thrive. Dams could fail which may result in flooding and destruction of property and people. “More than half of the world’s large rivers are fragmented and regulated by dams, including all the largest and the most biologically diverse rivers,” according to new research from the University of Umea in Sweden and the Nature Conservancy in the United States. Many water problems occur with the development of dams, and present approaches may not be sufficient in the future.
