By Monday we will have 7 billion humans on this planet. 4.5 billion is the target for a sustained way of life by today's standards. If most were still 3rd world natives, it wouldn't mater as much, but the 3rd world is becoming 1st world very rapidly. Resources will become scarce because developed people use 32x more resources than primitive folks do. We also discharge 32x more pollution. In 1999 we had 6 billion. By 2050 we will have over 10 billion people.
Want to talk jobs, food, resources...OUCH! Constant war is a very clear sign.
I'm only 39, so I will see this ultimate bubble pop.
