One of the major drivers of global warming is the greenhouse gases we emit by burning fossil fuels. Another major driver of global warming and one of the ways in which we are making our earth unsustainable for human life is the population explosion. When I was young the earth’s population was around 3 billion. It has more than doubled. When we talk about the growth of population, the crucial issue is about the time it would take to double. Population can double in as little as a generation. We are on the way to an earth with 12 billion people and counting. The devastation that is causing and will cause is incalculable and will make the earth inhospitable in short order, contributing to the overuse of water, the over fishing of the oceans, the deforestation of the jungles, the overuse of carbon based fuels even while we try to flush them out of the atmosphere and every other form of damage to the earth we depend on.
That makes population policy a tremendously important issue worldwide. Years ago we used to talk about ZPG, zero population growth. The idea had been talked about for centuries but a best-selling book, The Population Bomb, written by Stanford Professor Paul Ehrlich and his wife, Anne Ehrlich, helped make it a movement in 1968. Just a few years later, the movement was hijacked by the national battle over abortion. But population growth did not suddenly become unimportant. It remains at the root of the unsustainability of the world we inhabit.
We have a choice, we can curb the growth of population voluntarily, or an angry earth will do it to us, reducing our children and grandchildren to refugees, beggars, and marauders and leaving them to die of thirst and starvation or gasping for oxygen, if they are not killed by armed bands looking for the scraps of the earth.
Naysayers like to point out that Malthus’ prediction of worldwide starvation has not yet come true. But the evidence that Malthus’ prediction is coming true is all around us. Lands once fertile are becoming deserts. Trees once crucial to a sustainable atmosphere are being chopped down at alarming rates in the southern hemisphere with worldwide consequences. Fish stocks have been shrinking and even more important, the coral reefs that are at the base of the oceanic food chain are dying. May Malthus rest in peace, but we are seeing what he feared. Human beings have never been good at listening to prophets. Those of us living now can’t claim we were not warned. We can only claim that too many people scoffed as they scoffed at the prophets of old. The earth will have its revenge.
I do not want to treat abortion as part of this problem because it raises so many separate issues and debates. But I do want to treat almost every other method of birth control as very much part of the issue. Whatever your faith, we have an obligation to life, to treat our world with the respect it deserves. Religious proclamations about populating the earth made thousands of years ago have been accomplished, and must now be subordinated to religious and secular claims about life, about treating each other as required by the Golden Rule, about protecting the soil and the air and the water that give us all life. There is no escape from that injunction. Or the earth will have its revenge. Make sure the people you elect start protecting us from world-wide disaster.
