What could intervene?


1. Starvation - Can we feed 8 billion people? Some say no.
2. Disease Epidemic - SARS, a new bird flu?
3. Nuclear winter - nuclear war, comet, or asteroid?
4. Birth rate change
5. The Earth's poles flip
6. The Apocalypse (religion induced)


Check out "The Population Bomb" by Paul Ehrlich in 1968.

Disclaimer: Source: US Department of Commerce, plus other research.
There are many estimates of population for various time periods.
The reporting categories change over time, introducing discrepancies that must be resolved.
I have selected the numbers which are the most consistent among experts in the demographics field.
