I agree with the first point. Using our human bodies as an example when we get infected. It gets really warm. It's usually a technique used to kill bacteria among other defenses.

I don't personally believe it's some kind of "I got my peace for a brief moment and want more" thing. I just believe that we ramped up production after the COVID "recovery" period and we went back to business as usual at a rapid rate.

Absolutely true, although imo not necessarily as a conscious choice. It's simply earth's feedback systems. We cram all kinds of animals together and accidentally breed highly contagious viruses, which come back to bite us in the ass. We destroy biodiversity and now people in certain parts of the world have to manually pollinate crops, because the insects all died. Etc.

If all goes well, earth will find a balance again that still favours life (possibly not human life). If not, earth might end up like Venus. Not a big deal for earth, but a bit of shame of all this life we currently see here.

I get where you're coming from, but rather than the "earth trying to kill us", we are causing the earth to kill us through our own selfishness, willful ignorance and greed.
