Depends on what you consider clean. By most standards, most of the air on earth is clean. The part that gets people is that because of population density, many people live in areas without clean air. We also have some events like forest fires that can affect large areas for relatively brief times.
So it's not about running out of clean air on earth, but more so about specific locations and individual exposure.
- hackerlight 3y agoThere's some evidence that higher order cognition is negatively impacted by small changes in carbon ppm. I don't have the study on hand.
- giantg2 3y agoMost of the ones I've seen related to this deal with interior air quality, and the changes are not small when measured as a percent of change 150-300%. So local/individual scenarios could be a factor, but not globally.
