overpopulation

The video " 7 billion people everybody relax" exactly showing what happening in our planet, as our life runs  more better than usual, our population keep raising without limit. We know that there will be no more land to fill, if our population keep raising without a limit. For now there is a children die for hunger in every 5 seconds, even we tried so hard to help them! But as the population growing, there will be less land for agriculture, which it mean as our population keep raising there will be less food for everyone, so there will be more people hunger!

I consider what gonna happen will our population out of control in some day, are we going to control our population as how "to be or not to be"  do? Limited the born? At the end of the video it said " at the end of the century the population will be decrease."  people dying because there is more people come to this word? It not making any sense. people  expense their life for the new... 

And I don't think "fill" in those verses, means so much a specific "fullness" level, but more a continuing process, a reason why the most densely populated regions should go on multiplying as much as God allows us to grows our numbers.
