Don't feel bad. It's good for the planet and society to reduce the population somewhat. It can't keep growing forever. All the major problems we have are a result of it. Climate change, housing shortage, resource conflicts etc.

The demographic problems during a decline are only temporary.

If the world had only 1 billion people it would be a lot easier. The whole idea that humanity would go extinct is ridiculous. And humanity is still growing anyway due to the many countries that don't have falling birth rates.

There's always people wanting to have kids. This is just society adjusting itself to the current overpopulation.
