Agreed.
Our modern social apparatus: education, health, police, justice… contributes about 1.4 teqCO2/person/year. Just our breathing, for a single person, emits about 350kg of CO2/year. This carbon we breath out is accounted for from our food. But you have to understand that it is the absolute minimum a living human being can emit.
Now, that leaves about 250kg eqCO2/person/year for everything else: housing, heating, leisure, traveling, clothing… if we think we need to stay under 2t eqCO2. This completely impossible.
Whereas if we were half as many, like 50 years ago, 4t/person/year still enables us to live a modern life.
