Just two centuries ago, Earth's population was less than a billion. In fact, the population became one billion in 1804. The rate of birth was nearly the same as the rate of deaths. But then, better agricultural and better medicine caused the rate of deaths to be decreased.
From that point, the population began to increase exponentially due to the higher life expectancy for children. The population was doubled within 130 years and doubled again within another 50 years, reaching the limit of 4 billions in 1975. It took only another 10 years to increase yet another billion. In 1999 the global population was 6 billion. From 2011 the population is 7 billion and it is still increasing.
So, where will it end? Or better, will it ever end? Of course it will. Actually, U.N forecasts that the world population will reach the maximum limit of 10.1 billions by the year 2100, and then it will begin to decline.
It is not simple to get the exact numbers since a slight change in fertility rates could mean a population of 15 billions instead of 10 by the end of the century.

The only way it will level out is if our resources run out - in which case life will NOT be worth living for those remaining.
The UN has been totally discredited over it's global warming hoax, over population is by far and away the world's greatest threat and the UN is trying to cover that up because the solution is not palatable to them.
Third world countries are NOT going to stop having babies - period.
