In 1950 the global population was about 2.5 billion. Today it is over 6.6 billion. The US had a population of 151 million in 1950. We just about doubled and much of that was immigration from other countries where people have more babies. In 1950 Kenya was about 6.3 million. It is now about 6 times that amount. Kenyan women have more babies today (4.9) than they did in the 1990s (4.7).

No, I am not going to continually lower my living standard while other people keep making lots of babies.

Need
Greed
& Breed

are a disastrous combination.
