In next 100 years , people might become 15 billion .

In 500 years , 30 billion .

But rivers will still remain as many as there are .
Forests will remain limited .

Like apartments are now made for people to live , in tall buildings .

In future buildings will be made in which the ocean water will be processed and made for drinking .

Because rains are limited around earth as well .

If some one tries continuously to do Artificial rain , it will disturb the global system .

Water is more precious than gold ,
not only because it fulfils thirst ,
but because it is also needed to grow crops .



Maybe the fresh water use should reduce in less useful industries , where thousands of litres of freshwater is wasted daily .

Rivers will not increase on earth , roads and highways may increase .

And population will explode , like a nuclear bomb , and indecent videos and display of body parts had made people more aroused as well .
