Plenty of space? Where, in the dessert? Or upwards in a skyscraper? Perhaps built on a junk pile like Manhatten, or whichever NY city it is. Every year in America alone we lose millions of acres due to home, businesses, and highways being built. And a lot of that is farmland. The farmlands of the world are shrinking each day while the population keeps going up. It's just a matter of time.

And how can gov pop control be economically hurtful when there are still people that are hungry and jobless? For instance, take away 100million people spread across the earth. There would be no reason for anyone to be jobless unless due to injury or illness. OR, what if those 100M souls were the homeless, there would be no more spending on feeding them or for health care. Taxes and costs of most items would go down. Economically helpfull.

In developing countries more people raises output and as a country becomes developed people have less children. Wealth isn't fixed. Those people are not jobless because of overpopulation...in an unregulated market anyone can open a business and create a job. Either way, I wasn't saying that there wasn't some level where population can't be above what is optimal... but that population control by the government is always economically harmful which does not help poverty which is why people go hungry. Go back up a few posts and read the family senario. Apply that to a bunch of families. Wow. I must be bored. lol

Who gets to determine who gets to exist? How do you get rid of certain parts of the population? You can not do it morally or ethically. You can't do it. What about education? What about technology? The earth has plenty of room and resources well into the future. We can't entertain these type of thoughts. We can't start allowing people to control us out of fear.
