I found this site through a friend. Very interesting the way they put it. Basically gives a breakdown if you made a village of 100 people with the whole world population, and then breaks it down even further. Hard to explain without getting too...
It is beileved that carrying capacity of world for population is about 50 billion which is just 80 years away from today...
today the approx population is 10 billion.
What do you think you should do for that...
