That is - a anthropomorphization of nature- assuming what is nice and "stable" to me, is not actually furiously attacking one another. Nature had buildup of warfare materials (the plastic that was trees before fungi digested it).

Nature had campaigns ebb and flow, due to iceages and warmspells, had island holdouts being wiped-out by systems adapted to furious combat on continents (invasive species).

Your picture of nature is very much distorted by a rejection of a rather cthullian reality.

What you mistake for peace is a coldwar equilibrium, where all sites furiously roll the dice of research for new war-tech- and then humans came along. Humans are very much a natural system doing natural things, very successful though.

Cancer is natural, "natural" does not mean good. This focus on things being "natural" is very strange when we're discussing artificial constructs like the economy or technology.

Technology and capitalism are not natural phenomena, they are political ones.

You are conveniently ignoring the comparison to cancer. Capitalism and cancer both demand growth at the cost of everything else. This is what leads to them destroying the systems they inhabit.
