NASA Model Reveals How Much Pollution Levels Changed Due to COVID-19 Lockdowns

[Zellmer, Robert]

Ch 18 (environmental chem) is NOT on the final.  We did over go over a little bit of it.



I found this recently.  It shows how pollution levels fell during lockdowns.  I've seen other similar studies.

I also saw something about how the background vibrations of the earth decreased during lockdowns

because there were fewer people out and about.  So I guess maybe humans do effect the Earth's

environment.
