I don't know really what you're arguing. I don't think that the poster was suggesting that we go back to the flintstones-age, and I'm sure he/she was appreciative of the work that's been done in the past, but that in no way deters from the fact that current and future generations are going to have to do a lot of cleanup from the past generations.
If your parents died and left you an inheritance of $1000 and also a debt of $100 you're still $900 ahead. Most people wouldn't call that being "punished."
Oh, I totally get that society has benefited from our 150 years focus on using the concentrated energy found in the ground.
The hell of it is that we've only had a reasonable understanding of the dangers associated with using this energy for a few decades. I find no fundamental fault associated with their decisions back in the day.
All in, the gains you've received from your ancestors FAR FAR outweigh the losses.
