Yes, I did read the whole essay.

"Parents are supposed to want a better life for their children than they had themselves, but children being born now will face suffering on an unprecedented scale and we know it."

We don't know that. You seem to have a religion like belief that will happen, but most people don't share your utter pessimism. People in the developing world have a pretty good idea what kind of privation and suffering their children will have to endure at a level we can't even imagine, yet they have them and love them anyway. Suffering is part of being a human, by the way. "An unprecedented scale" of suffering vs. what? World War II? The Cultural Revolution? The Congo War? The Spanish Inquisition? The 30 Years War?

The title perfectly conveys what you are trying to say.
