Water scarcity map shows that India and China will have big problems with physical water scarcity in years to come.
It is reported that a billion people in the world do not have access to safe water (one sixth of world's population). This is not so surprising when you consider that the world's population tripled in the 20th century, and the use of renewable water resources has grown six times. You can imagine what is going to happen in the next 50 years as it is expected that world population would increase by another 40 to 50 per cent. Water will very soon become the most precious resource on our planet since without the water there's no life, and countries that will struggle the most with water scarcity are very likely to be India and China, that have massive population but lack both enough water, as well as the needed infrastructure to tackle water pollution.
