Which method of avoiding water shortage is more valuable: developing new sources of water or conservation of it?
More than one-third of all worlds will likely be facing very serious water shortages by 2050, according to a new report released by the Natural Resources Defense Council. Up to date, approximately 700 million people in 43 countries suffer from water shortages. High rates of population growth, poor management, environmental pollution, low water use efficiency lead to the depletion of water resources. The United Nation Secretary-General Ban Gi Moon noted that in the future water shortages will pose a threat to economic and social development and environmental sustainability. He believes that in order to overcome this problem is important to the integrated management of water resources and international cooperation, as many rivers and aquifers are the common heritage of countries.
