So you'd have to launch into spacepeople every day just to break even. If you wanted to reduce global population, you'd have to launch more than that.
It is a lot easier to use contraception. The other thing to note is that as nations become industrialized, their population growth tends to level offor even decline.
This removes population pressure as a colonization motive. I had listened to the news on the way home; it wasn't good. The ration had been cut another ten calories—which made me still hungrier and reminded me that I hadn't been home to get Dad's supper.
The newscaster went on to say that the Spaceship Mayflower had finally been commissioned and that the rolls were now opened for emigrants.
Pretty lucky for them, I thought. No twerps like Jones. And a brand new planet. The spuds were ready. I took a quick look at my ration accounts, decided we could afford it, and set out a couple of pats of butterine for them.
