We really don't have to do anything...

Diseases like Covid will eventually take care of overpopulation.

It's nothing new either... Even I 30+ years ago in basic high school biology we were taught that monoculture invites disease...

None of what we're going through now is anything we didn't know 40-50 years ago.

As a species we're just experts at complacency and ignoring everything that doesn't impact us directly...

It's going to catch up to us one way or the other...
