Stanford University biologist Paul Ehrlich's book The Population Bomb was published in 1968, a year when the rate of world population growth was more than 2 percent-the highest in recorded history.
Although the population is still increasing, the rate of increase has halved since 1968.
There is more genetic variation in a few troupes of wild chimpanzees than in the entire human population.
Another reason for the downturn in population growth is economic.
An additional factor in the shrinking rate of population growth is something that can only be regarded as entirely welcome and long overdue: the economic, reproductive and political emancipation of women.
Having fewer children, and doing so later, means that populations are likely to shrink.
Humans occupy more or less the whole planet, and with our sequestration of a large wedge of the productivity of this planetwide habitat patch, we are dominant within it.
