I decided to put into Yahoo search the phrase "myth of overpopulation" and see what I could find. That brought up on 1st entry a site called overpopulationisamyth.com. After poking around, I found a link to a UN study on Population, and this was part of the data being discussed:
When has the world population reached or is expected to reach each successive billion?
So here's what I see: Between 1959 - 2011 (52 years,) we gained 4 Billion People.
It is estimated that between now (2012) and 2083 (71 Years) we will gain an additional 3 Billion.
We gained an average of 75 Million or better per year in the 1st 50 years.
We will get an average of just over 40 Million per year in the next 70 years.
Looks like the population is slowing down, to me~!
