Perhaps but I doubt anyone here is going to publicly admit support for mass murder on the scale of hundreds of millions as a means of dropping Co2 output. At least not without enough hatred and resentment drummed up for whatever arbitrary label of people that's unfortunate enough to be the sacrificial goat.
This seems to be regularly suggested here. And the general target seems to be the poor, because then you can tell people they need to kill the poor or become poor themselves. So it's a simple case of them or us.
Literally the same argument that Hitler made:
> The Nazi Generalplan Ost policy ('Master Plan for the East') was based on its tenets. It stipulated that Germany required a Lebensraum necessary for its survival and that most of the indigenous populations of Central and Eastern Europe would have to be removed permanently (either through mass deportation to Siberia, extermination, or enslavement) including Polish, Ukrainian, Russian, Czech and other Slavic nations considered non-Aryan.
No, that's not what efficient means. Most people are happy to be alive, and their existence is a good thing. Your comment is an example of misanthropy sometimes found in climate activism and environmentalism more broadly.
Nah just put them in a pod, matrix style, as efficient as it gets, no more physical strain, no more "what am I going to cook tonight", the transhumanist dream
Actually the massive efficiency of the current world depends on lots of people. Reducing populations will result in less efficiency.
Instead we should be trying to grow populations as we're headed for a demographic collapse requiring extremely high taxation of the young to care for the old. It's a slow moving disaster.
