. What could intervene? 1. Starvation - Can we feed 8 billion people? --- Many say no. Drought-induced famine 2. Disease Epidemic - --- SARS, a new bird flu, Ebola? 3. Nuclear winter - --- Super volcano, nuclear war, comet, asteroid? 4. Birth rate change --- Happening now 5. The Earth's poles flip --- Calamity, happened many times before 6. The Apocalypse (religion induced) --- People lose their minds on massive scale Check out "The Population Bomb" written by Paul Ehrlich in 1968.

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.
