POPULATION GROWTH
Debate over what the Earth can handle
I am writing in response to "Look askance all you'd like — we'll make more" by David Paul Deavel (March 2). I suppose we should expect a defensive tone from an associate editor of Logos and a fellow of the Center for Catholic Studies at St. Thomas. Still, it is sad when intelligent and educated people ignore the facts and science of the population explosion.
The Earth's population is now at 8 billion, and has doubled in 45 years. Some have said the carrying capacity of the planet is 2 billion. The surplus of people takes its toll on farmland, which has dropped by half per person since 1960.
It takes its toll on fresh water, which has dropped by half per person since 1960, and is causing our aquifers to dry up and water tables (as shown by White Bear Lake) to decrease. It takes its toll on our forests, which have also dropped by more than half. It takes its toll on oil and gasoline supplies, on fish stocks, on animals becoming extinct, on vital minerals and on other resources.
Our population is far beyond sustainable levels. Nearly every problem of the world can be traced to this basic problem.

I read with great concern a recent letter that asked of the Catholic Church: "Shouldn't tackling the issue of overpopulation be a moral imperative?"
According to Austin Ruse and his essay "The Myth of Overpopulation and the Folks Who Brought it to You":
"[T]he theory that the world is so awash in people that it will eventually die is false and it always has been. We will not run out of food, natural resources, or room. The theory is completely and dangerously false. The world now produces more food on less land than ever before. The world is awash in food. The problem is getting it to the hungry. Starvation occurs in the world today not from lack of food but generally as a result of bad policies or the use of starvation as a tool of war. Also, the cost of natural resources is now lower than forty years ago. Price is always a marker for availability: lower prices mean greater availability. Why are natural resources more plentiful? Simply because of our ingenuity. Mankind is better at getting natural resources out of the ground, whatever they are, and we are more efficient in their use."
