People born before the 1980 are also of significantly lower IQ up to a 7-8 points due to leaded gas use. The boomers and gen X really did a number on themselves with environmental hazards.

In countries that phased out lead later, even early Millennials faced similar or worse childhood exposure. It’s a global generational story, just with different timelines by country. As a personal example, Romania only phased out leaded gasoline at the end of 2004.

Some places still allow it in civil aviation too.

A necessary (?) part of progress IMO. Environmental hazards have been a thing for a lot longer too. Settlements used to be covered in smog due to coal fires for example.

Part of the environmental/emissions argument from developing countries is about past emissions by developed countries. I think it's a fair argument to say given these sacrifices made by past generations in industrialised countries + the benefit of developed cleaner technologies through that industrialisation is an argument against that.

> Settlements used to be covered in smog due to coal fires for example.

Used to? Lots of them still are. Right now there's 150 µg/m³ of PM2.5 outside my window, and it's a "clean" day. Yesterday's concentrations were up to 900 µg (yes, that's correct), and the highest I've seen this winter were 2000 µg (yes, this is also correct). And it keeps getting worse, recently our so-called president mentioned that coal is our strategic reserve and we won't be phasing it out any time soon.

I'm relatively sure most of the "global south" has bad air quality, even if such extreme values are rare.

Here are some random photos of a typical winter day (winter is 8 months per year):

London first tried to ban burning coal within the city in 1306 due to the air quality.

Us GenXers didn't do this to ourselves. Boomers (and their parents) did it to us.

I was born '74. Alberta, Canada. I remember people raising a huge stink about "guvmint' interference" when leaded gasoline was banned and when seatbelt use became mandatory. And don't even get started about cigarettes and mandatory separate smoking areas at restaurants etc.

"Liberty" and "freedom" were concepts substantially abused and misapplied throughout the 20th century.

I have no concern for young generations wanting to blame our age group. The day will come soon that their generation is pointed at for not solving the complex problems of their day. Now if they will show me the same grace when I start a story with "back in my day" we will all get along.

They still are. Measles was on the road to being eradicated until 10 years ago.

Gen X also gave you the web, google, facebook, YouTube, twitter, and additive algorithmic brain rot. So who got the better deal?

1901 Oldsmobile curved dashboard was the first mass produced car. Lead was introduced to gasoline around 1920. You want the "Lost Generation", born 1883-1900.

Question is what is worse for IQ development in children/teens: exposure to leaded gas or TikTok?
