Air quality. I grew up in the Los Angeles basin in the 70s and 80s and remember having to stay inside because the smog was so bad - Stage 2 smog alerts, they were called. Apparently they haven't had one of those since 1988. Haven't had a stage one smog alert since 2003.

(Mind you, more wild fires now, impacting air quality. Even so.)

Also in no particular order: TVs, long distance phone calls, bicycle shifting and clipless pedals, tires, outdoor clothing, dishwashers, digital cameras, computers, home construction (esp. insulation&air sealing), dentistry, and electric vehicles (which are amazing!)

All right, but apart from TVs, long distance phone calls, bicycle shifting and clipless pedals, tires, outdoor clothing, dishwashers, digital cameras, computers, home construction, dentistry, and electric vehicles, what have the Romans ever done for us?

The air in Denver is vastly better than 40 years ago, well maybe not today due to wildfire smoke, but overall it’s better. We still get high ozone days (worse due to altitude), but now the infamous brown cloud is nothing like the 70s and 80s when you couldn’t see downtown from the foothills.

Unfortunately air quality improvement and food improvement (water too) were driven by policy choices (clean water act/air act) that were made when both parties were actually interested in governing. It gets a lot more difficult to sustain that with the GOP being a nihilistic band of grifters.

It reminds me of how people with chronic conditions will sometimes stop taking their meds because they "feel fine now," only to discover that the meds were the reason. Now people are shredding environmental protections because they've forgotten the reason we can all breathe outside.

Almost everything is better now than it was 40 years ago. If anything, you always want to live in the present because of medical advances alone.

The general decrease in pollution and measures taken by conservation groups have brought the bald eagle back from the brink of extinction, too. As a kid in the 70s, I never expected to see a bald eagle in the wild. In recent years, we see them all the time and every sighting is still a thrill.

Same! I was once on a fairly busy road in my town, and a bald eagle clutching a fish flew low over the road. Every single driver slowed to watch (or possibly, and thankfully, to avoid hitting those who slowed down). Always a thrill!

How very cool! The return of the bald eagle is an amazing success story for conservation. We had a nesting pair up in a tree at the local PDQ chicken place when I lived in FL. People would stop and take photos of the chicks in the nest and it seemed so very magical.

Ruston, WA, just outside Tacoma, used to host the Asarco smelter. "The aroma of Tacoma" was well-known then, especially when a temperature inversion over Puget Sound would trap the air and spread the acid, eye-burning stench as far as Bremerton and Federal Way. It became one of the first EPA/

/Superfund cleanup sites. Today, 50 years later, you can't eat fruits or vegetables grown in that soil. Now the "Aroma" is just the pulp mills on Commencement Bay, which smell vaguely unpleasant but only in that immediate area and have never caused nosebleeds (common with the smelter fumes).
