Consider for a moment: on this planet there are six plus billion people, and if I remember the numbers correctly, every hour we have a net gain of about 9,000 people per hour. I'm taking all those who died off and all those who come to life, the net gain is about 9,000 people an hour. That’s why we can move in the next 25 years from 6 billion to 9 billion people at the present rate of growth. That is awesome to consider!
