[NSFW] How do we limit births to avoid disaster due to resource depletion, pollution and destruction of nature?

When I was born, there were about 2.2 billion people here on Earth. I’m about to turn 70, and in the 7 decades I’ve been here, Earth’s population has grown by more than 3 times the amount in grew in the first 200,000 years of modern humanity inhabiting this planet. The UN predicts Earth’s population will hit 8 billion in another 15 years, 9 billion in 2050, and 10 billion by 2100.

Still, the leaders of many religions and denominations, always ravenous for a larger flock to pour more money into their offering plates, are exhorting their faithful to make babies as fast as they can pop them out. But we are running up against resource, pollution and habitat destruction limits now far faster than technology can solve those problems. We have to start limiting births. China’s one child per couple approach was as disastrous a failure as it was a barbaric policy. How can we maintain population at what it is now or even decrease it a bit over time? How do we limit births when medical science progresses to the point where, barring accidents or murders, humans begin to approach living forever? If celibacy isn’t an acceptable answer what do you prefer we do?
