2. It's obscene-one species crassly treating a whole

Planet as solely a backdrop for humsn activity and prioritizing our most frivolous demands over even minimally decent treatment of the planet or its non-human animals:

I was grossed out by this 5 years ago:

Global human-made mass exceeds all living
biomass

Published online: 9 December 2020

Humanity has become a dominant force in shaping the face of Earth1–9. An emerging
question is how the overall material output of human activities compares to the
overall natural biomass. Here we quantify the human-made mass, referred to as
‘anthropogenic mass’, and compare it to the overall living biomass on Earth, which
currently equals approximately 1.1 teratonnes10,11. We find that Earth is exactly at the
crossover point; in the year 2020 (± 6), the anthropogenic mass, which has recently
doubled roughly every 20 years, will surpass all global living biomass. On average,
for each person on the globe, anthropogenic mass equal to more than his or her
bodyweight is produced every week. This quantification of the human enterprise
gives a mass-based quantitative and symbolic characterization of the human-induced
epoch of the Anthropocene.
