When Industrialization and urbanization flourish without taking into account the natural law, the greenstuff wears off.
Not protecting and not swelling the remaining greenstuff have destablized the water balance in the soil and thus global climate changes and droughts came into existence.
In other words the nature have reacted this situation.
The potable water sources that have been used and couldn't return to the earth again until today, came in to the point of extinction.
The air pollution caused by the greenhouse gases spreaded into the athmosphere have accelerated this.
Anyway, this is no more a issue of saving the next generations but the problem of present day.
For this reason, expending the water consciously and reusing the water by recovering as much as possible should be the only goal of us.
With practiced projects of recycling, when the total expenditure of management and investment is compared with cost of the water that is obtained from available resources, it can be seen that it is compensated.
After a year, the loss turns into benefit. Yet, the real benefit comes with the protection of our water sources and multiplication in time.
