Population Counts – It Has to Drink
You have read me on this blog and perhaps heard me on television and radio, arguing the primacy of population. The explosion of human numbers. A lot of what is happening in the world can be explained by the disproportionate increase in human numbers: the degradation of the oceans, the spread of desert in Africa, the purging of the tropical rainforests, the elimination of species like the African great apes, and tribal warfare and civil war.
The world population has doubled since 1970. Doubled in 40 years, and it is going to go on increasing before it stabilises. Perhaps around 2050.
To put it crudely, you don’t have global warming without global swarming.
Just came across a statistic that clinches the case. According to James Famiglietti, a professor of earth-system science and civil engineering at the University of California in Irvine:
We have the same amount of water…
The laws of supply and demand might make new resources of oil and coal feasible, but economic laws don’t work magic with water.
So we have the same amount of water, but we have – wait for it – 250 percent more people than a century ago. And climate change means “water moving around to different places, even as populations are growing.”
The result is not only a shortage, but a mismatch between where water is and where it’s needed. At the core of the problem: human numbers have doubled since 1970.
