I look at our g'kids and I'm afraid for the world they will live in.
We live in the most prosperous time in history. Could it end? Sure. I am certain that during the depression and the world wars, many people thought about bringing children into the world.
If humankind lived in fear of the future, we would be dead eons ago.

The difference between them and now is that people are not doing better than their parents. As long as the inequality of wealth changes, that will only get worse and worse.
Climate change is having a negative impact on almost every aspect of some people's lives and that is not going to end with poor countries.
RWNJs like to pretend they and their spawn don't have to worry about it.
