Future wars may be caused by spores, not with gold or oil, and for the most available people resource — water. More than half is water; from water came the first mammals in the water was born the first life; without water a person will not live a couple of days. So if you take away his access to fresh water, mankind will be threatened.
Scientists from the Potsdam Institute specializing in the study of climate change, said that climate change will have a serious impact on the world inventory of water resources. More than a billion people live in countries with insufficient water quantity, and population growth in these regions in the future will only aggravate the situation.
What will become of the water on Earth
The study pointed out that even if the average global temperature will increase two degrees Celsius per year, which is the most optimistic scenario, soon nearly a billion people leave their habitat because they generally remain without water.

According to one expert, more just global warming will hit the center of Africa and South Asia, and then will affect the Northern regions. It is unknown when it will begin a “water crisis”, however, a number of countries are already beginning to carry out some measures to reduce the consumption of water per person. California Governor seeks support from the state to protect farmers from drought.
For clarity, scientists have made a map and identified the countries where water shortage will be most noticeable (they are highlighted in blue and cyan). It is noteworthy that in Russia a water shortage is expected only in the European part, and the first time it will not be visible to the population of our country.
Earlier this year, experts from Columbia University stated that “water crisis” will affect a lot more regions in the US than it was assumed before, including new York, Los Angeles and even the country’s capital — Washington. All because of the increase in population in US cities: in 1950 it grew by almost 99 %, while water consumption increased by 130 %. If this trend continues, the only solution will be more efficient use of water.
The growth of the world population (current and projected) in millions of people
We waste water as they want, because it is cheap, says Tess Russo, a scientist from Columbia University.
How to solve the problem of water scarcity
Rousseau argues that technology for efficient water consumption there are now, but to get farmers to spend money on expensive equipment is not easy. Therefore, for the implementation of such programs is extremely necessary government support.

To help also can come the discovery of new sources of water. So, in June, scientists uncovered one of the largest reserves of fresh water. It turned out that the freshwater stretch from Massachusetts to new Jersey, and the affect of Delaware, new York , Connecticut, and Rhode island. Having 350-km length, the reservoir contains 2.8 cubic kilometers of low salinity water. However, before use of such water, it must desalinate.

According to experts, the reserves could be formed 15-20 thousand years ago. And who knows how many water sources still have in the world about which we do not even suspect.
Anyway, if you do not start to save water right now, the consequences could be disastrous. Not for us, but of our descendants. And although in Russia the shortage of water the first is not too obvious, in the future, the chain reaction will affect all countries. Think about it next time without the need to leave the outdoor faucet in the bathroom.
