In the late 1960s, “The Population Bomb” by Paul Ehrlich spread fear that the earth would soon be unable to support an exploding global population.
Ehrlich, a professor of population studies at Stanford, pushed that dire message home in his book, on television, and in lecture halls across the country.
It quickly became a talking point for television news anchors, late night-talk show hosts and magazine writers. His supporters pushed for families to have fewer children, and touted the benefits of Z.P.G. – zero population growth.
Ehrlich himself was increasingly alarmed that untamed global population growth might destroy the planet within 15 years. He even talked about the need for compulsory methods of population control, like a tax on children and luxury taxes on diapers and cribs if all else failed.
Ehrlich’s belief that population was approaching the exhaustion of the food supply hit home in India, which launched a controversial sterilization program in the mid-1970s that affected 8 million people. But his dire predictions overlooked the so-called Green Revolution of the 1970s, when high-yield seeds, pesticides and better farm management triggered a boom in food production world-wide.
Over the decades, those advances have lessened hunger in India and across the developing world. As efficient farming has increased, the need for large families to run those farms has decreased as well.
There’s no doubt that Ehrlich raised awareness of the impact of population growth on the environment, but his story shows the danger of underestimating mankind’s ability to change.
- In the 1970s, why was Paul Ehrlich worried about the “population bomb”?
- What solutions did he propose to limit population growth?
- How did the Green Revolution affect hunger in the developing world? What effect did it have on public concerns about overpopulation?
- How is India managing population growth? Which policies have they tried? Which seem to be the most successful?
- Why didn’t the most extreme predictions by Paul Ehrlich come true?
- Paul Ehrlich said the idea that women should be allowed to have as many children as they want is comparable to someone saying they should be able to throw as much garbage into their neighbor’s yard as they want. Do you think this is a fair comparison?
- Based on your level of concern about overpopulation, what policies (if any) would you support to reduce population growth? Would you support government policies limiting family size? Tax incentives for families with fewer children or none? Increased taxes on toys or diapers? Sterilization programs?
- At the end of the video, Stewart Brand says a problem in the future might be that we’re “running out of people.” Why are some countries facing a problem of too few babies, and too many aging citizens?
