To be brutally honest, if a rogue CIA wanted to slow down CO2 emissions, that sort of virus was a good fit.
I really wish humans would organize and agree to reduce emissions, but since it's geopolitically just not really happening, that virus is a good coincidence.
If it was engineered: good. If it wasn't, that's also nature reacting the appropriate way. If it was negligence, it was a happy one.
Disclaimer: I have chronic depression, and a therapist told me that I felt happy during lockdown because average people were finally sharing and experiencing my distress. It really stuck with me.
