Now the amount of stresses each human puts on the system both directly or indirectly is pretty large. Humans need to eat, so we have a footprint for that. We need transport, shelter, heat when it's cold, etc. And all that impacts the environment. Even when there were 2 billion of us the Earth could decently manage the impact, but we're over 7 billion now and the Earth is creaking under the strain. I've felt for years the biggest problem is not the CO2 we're generating but the total size of the human population, CO2 is just one of the effects. The Earth would be better off if we got down to about 2 billion of us, but doing that in less than 1+ centuries goes down roads that only monsters would contemplate.
Monsters are contemplating it.... and they're quite open about it. Georgia Guidestones being just one example. Of course they'll never require THEIR families to reduce THEIR footprints, it's only for us SERFs. It would also be extremely helpful if the elites would stop suppressing technologies that would allow the earth to sustain 7B or even more human beings on this planet with no problem... Without going into any of these here, people do die mysteriously all the time when they come up with something revolutionary that would reduce our dependency on the current energy monopolies the elites control.
