The storm is when you know the good pilot ever reads, is published, comments on the serious problems facing planet Earth in relation to the contamination of the element water, vital in our life. It is of serious concern, that warnings that thereon made already about the scarcity of water in many countries has been taken seriously by Governments, even by citizens who require this element to ensure life. . Not surprisingly, we read, you point out, that one of the main negative effects is already having on our daily life the unsustainable use of natural resources and its consequence more devastating, global warming, is the difficulty of access to drinking water. The Earth contains approximately 1.4 million cubic kilometres of water, but around the 97.4 percent are locked in polar icecaps and glaciers. Available fresh water is reduced to 0.001 per cent of the total. In Latin America and the Caribbean, increasing the consumption of water from the year 1990 to 2000 in a 45 by cent, from 150 to 216 cubic kilometres per year.
The urgent need to tackle the geometric progression of the demand for freshwater in Latin America and the Caribbean complicate even further if, as current trends indicate, left the resource base to deteriorate at one ever increasing speed. Definitely, nobody can doubt the importance of water, perhaps the only essential element for the development of life. The scarcity of fresh water worldwide is a dramatic priority problem, since it represents a very limited percentage in relation to the total water in the planet: only 3 per cent, of which less than 1 percent is accessible, since the rest is frozen in glaciers or at great depths, as in the case of aquifers. The remaining 97 percent is salt, water not suitable for the majority of human activities. Ricardo Natalichio provides us with, that rivers, lakes and even the vast oceans are victims of pollution to such an extent that in many cases of source of life have become hotbeds of disease transmission and synonym for death.However, modern life as it has been nurtured continues pointing out each time more and more natural resources for their fictitious consumption needs.
