This Planet Comes with Limits

When I was in my 20s, a girlfriend surprised me by saying that we didn't have to worry about overpopulation because technology would make sure we always had what everyone needed. Of course, economists have been saying this for decades.

And of course, billions of people today don't have what they need.

Because such people as my old girlfriend and economists presuppose that unlimited economic growth is necessary and also believe adding billions more humans to the world is desirable, I would like to share some thoughts about such thinkers, whom I'll call "Growthers."

Why do Growthers think we should add billions more humans to the world? Do they want more consumers? Or is it something deeper, more biblical, more fruitfully multiplied? All of the above? Whatever their impulse, compulsive craving for "no limits" to economic growth and human numbers is irrational. A finite planet comes with limits.

The United Nations expects the population to grow to about 9.6 billion people by mid-century; that's two more Chinas. That worries me. Yet in The Wall Street Journal on Saturday, April 26, Matt Ridley expressed these views when he reassured us, "There are no limits because we can invent new ways of doing more with less." He doesn't see that this very acknowledgment undermines his premise. If limits don't exist, why would we need to do more with less?

He continued: "Oil and gas ... will run out one day, but only in the sense that you will run out of Atlantic Ocean one day if you take a rowboat west out of a harbor in Ireland. Just as you are likely to stop rowing long before you bump into Newfoundland, so we may well find cheap substitutes for fossil fuels long before they run out."

Is it possible to think more incoherently about matters of such importance? And as a mariner I must point out -- if only for safety -- that a rowboat far in the open ocean is a frail and vulnerable craft.
Another big blind spot in the unlimited growth view is the fact that other species also need to live here with us. But other creatures pay for our growth. Meanwhile, populations of fishes, amphibians, mammals, reptiles and birds are all declining worldwide. Species are going extinct about 1,000 times faster than the natural rate -- in other words, the rate it would be if humans weren't around.

North America's pursuit of growth obliterated the tall prairies, exterminated the continent's most abundant birds and marginalized many mammals. An Africa of unlimited human growth will lose free-living elephants, apes and cats, natural landscapes and free-flowing rivers. It happens when farms and towns replace plains and forests.

Would farming Africa like we've farmed the Plains solve Africa's problems? Food isn't Africa's only problem.

Already, Ethiopia's planned dams threaten the nation's own people and Kenyans who rely on Lake Turkana for water and food. Competition and conflict always shadow the broad edges of humanity's tent, and a bigger tent tends to inflame tensions. Like all continents, Africa focused on growth would still have poverty, hunger and conflict. Better to focus on reducing poverty, hunger and conflict.
