Economics

I think its just nature and nature is brutal.

We are animals, we need to destroy the environment to survive (ex cut down trees for shelter, kill living things to eat). We have the urge to reproduce, so there is more of us which leads to more destruction. If a person is threatened, they will be prepared to kill another for their survival. This is pretty much true for most living beings.

I wouldn't call us a virus, but it was probably our intelligence that will bring us to our downfall. Maybe an anthropologist can comment on what the tipping point was.

So y'all just gonna ignore all of human history showing that it's not a modern thing?

Humans have been dog shit from the beginning. Always at war, multiple genocides, constant ethnic cleansings, torture en masse, all of these things have been prevalent in all of recorded history.

As bad as capitalism is it's just another example of humanities inability to just be fucking decent to each other.

Well, the largest expeditor of the problem, but still done by and for an infection.

We still made huge impact to the ecosystems in the past too, it's just that we now no longer destroy only local ecosystems.
