Is coronavirus nature's way of stopping global warming?Watch
With a vaccine we'd probably go back to where we were (and worse) pre-COVID.
A hypothetical zombie virus, or Ebola going airborne, would be much better at this.
Nope. As others said damn inefficient.
Plus, doesnt that rather require 'mother nature' to know how society works and how we'd respond? This being a fairly novel response and all.
