Hey guys!
I just came across a very interesting documentary. The title of the video might be a bit populistic but nevertheless it is a very worthy watch. The video focuses on the last century's population growth and presents a very interesting point in controlling the situation. In the latter stage it also adresses the issue of poverty.
If you do not have the time to watch the whole documentary I recommend starting from 8.00 minutes and watching until 11.00 minutes. I was really suprised and encouraged by the fact that average family size has changed so much in the last decades.
Next part I really recommend starts at 44.30 minutes and lasts until 48.00 minutes.
Enjoy. Best of luck!
