A couple points.
First, I agree with @Dr_Paprika and others, in that assuming ever member of a generation is all one thing or another is falling into such generalities that it’s meaningless. There were people that were actively part of the problem as well as trying to draw the public’s attention to the problem in that same generation. Sure, we could argue percentages, but it’s nowhere approaching unity.
Second, Cecil’s column feels a touch smug, coming down on the side that the baby boomers were overall good folks, and that things weren’t as bad as the doomsayers predicted. And he’s not entirely wrong, and is coming in from the perspective of dismantling the equally overwrought “they wrecked the planet,” but it isn’t a good look overall.
Third, being a late forty something myself, I periodically have to remind myself that the ease of getting information that we take for granted in the last 10-20 years, was NOT a thing for the majority of the time we’re throwing blame at the boomers. Yes, there were plenty of people who had good information on climate change and other environmental factors, and a few of them overcame the huge industrial inertia to bring it to the publics attention, but it was a major uphill battle against the invested interests.
Fourth, there is another problem with the assumption “Baby boomers wrecked the planet.” I most often (by no means exclusively) hear it from non-BB individuals who immediate say afterwards some flavor of “since it’s too late, nothing I can do makes a difference.” Which is also not helpful. We’re here, blaming someone else doesn’t mean you get to wash your hands of the problem. Especially when you use that excuse to continue to make the same mistakes.
Finally, though, back to blame issues, the BB are still part of the problem, just as much of as the rest of themselves. The toxic nature of American politics means that many of them are voting for representatives that are still trying to ignore or downplay the problems. Still by no means exclusively, but certainly as a higher percentage than gen Z + by all metrics.
So, in short, sure, they’re a part of a problem, along with the rest of us, and arguably they were the first generation that had the tools and information to realize the scale/scope of the issues, but were so busy putting out the small fires and NIMBY issues to actually do much to address the bigger issues… but that’s true of every generation. Right now, I’d love to throw less shade, and recruit as many as possible of every rational individual, regardless of age, to focus on keeping our blue marble intact and livable.
