The shutdown of economic activity and drastic reduction in the use of fossil fuels has of course led to a short-term amelioration in air quality, as the twin maps of China clearly shows.  But the jury is out on the critical question of what will happen as activity resumes.  Will economic pressure cause backsliding to abundant and cheap carbon fuels or will the Resiliency Lesson from our experience from the pandemic be learned?  We know that areas with worse air quality suffered more from the virus.

This was such an interesting one to see how quickly air quality improvements were noticed. It seems that if they can ramp down quickly, they can ramp up just as quickly-- but it should at the very least leave no doubt as to the direct impact we actively have on the environment around us.
