In the US, "Boomers" made the environmental movement mainstream, created the EPA, started cleanup of superfund sites, and passed the clean water and clean air acts. There are waterways where I live that are swimmable for the first time in generations because of the Boomers. It's not an either/or proposition.

Boomers didn't create the EPA, that was the Greatest and Silent generations. Boomers were no more than 25 in 1970 and hardly in power. Some of them may have been in the activists pushing for change but they didn't actually pass the legislation.
