You know that CO2 concentration is at 421 ppm, (0.0421%) up from 280 ppm in 1850? That change is negligible compared to the 21% oxygen. Standing in a crowd or being inside causes a much higher variation of the oxygen concentration. Even moving up 2 meters changes the amount of oxygen molecules per volume by more than that.
Even then, you’re going to get NOx. The atmosphere is 70% nitrogen and with high enough temperatures, some will always react with the available oxygen.
Isn’t that the same for Reddit or Lemmy? The content creators and mods don’t see a penny either. Operationally, a social network probably requires a lot more compute power and somewhat more bandwidth compared to a site that serves mostly static content. But I don’t see why small donations shouldn’t cover that. The cost per user seems moderate, otherwise few people could afford to run an instance with 1000s of users without charging them.
Dude, 13000 deaths are approximately 28% of the total traffic death toll for 2021. Even if I take the data for 2014, with the all-time low of 1.17 fatalities per 100m mi driven, that 28% is more than the 0.12 total fatalities in Germany (1.9 per bn km, 2018). Maybe the government could start fixing driver’s ed and make sure vehicles are actually road safe.
