Three times in my life I have discussed overpopulation with friends who are Catholic. All 3 tended more tothe liberal end of the political spectrum than to the Right. Funny thing is, all 3 used almost the exact same words to tell me that overpopulation is not a problem.

They say:

It's actually a problem of distribution of food and of politics, not overpopulation.

All the people on the planet would fit into Texas, with enough room for a suburban size lot and house for each.

etc.

I find their thinking frightening! I try to explain that we don't live in some ideal world! I'd rather provide birth control and have families have fewer children, than wait for change in distribution! (Wal-Mart has a good distribution network. Shall we wait til there is a Wal-Mart on every corner?)

Have you encountered the same thinking? How does one reason with these folks?
