Look at us desperately trying to grow/metastasize on other worlds, that we will struggle to exist on, as we continue to actively choke the one that birthed us and that we evolved to thrive on specifically.

It's a nice thought that any enlightened intelligent species would find technological harmony/homeostasis/equilibrium with their homeworld before setting out to explore or expand on worlds far less hospitable to their physiology.

We, on the other hand, seem to be pushing to expand at this point because we A) want to keep burning this world for short term profit and unsustainable growth/metastasis, and B) want to survive as a species for some reason after we've thoroughly accomplished that mission.

How are we as a species not a Macro-cancer of Earth? No interest in homeostasis, growth or die, indifferent to the reality that it's literally killing our host. That's malignant cancer. Hi.
