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 .

Earth's population will not increase that fast in the future, as a result of higher incomes and better education of people.
The third derivative of population growth is already negative ==> It's already sub-exponential 😏

@helenS People who have higher income desire 3-4 children .
Those with low income have 2 . Need for family and kids is by most people .
Yes in recent years diseases have increased death as well .

@Max41 That's a dumb generalization that you can't prove.

@Max41 It's a fact that uneducated people in very poor countries have many more children than people in 1st world countries:

"Democratic" Republic of the Congo: 5.72 births per woman (as of 2020)
Switzerland: 1.46 births per woman (2020)
Niger: 6.91 births per woman (2020)
US of A.: 1.64 births per woman (2020)
Mali: 5.63 births per woman
Canada: 1.40 births per woman (2020)

==> Population will decrease in all 1st world countries if not compensated by immigration.
