You people are overthinking It, you are not the cause for this thing called globalism or world existing. You do not have much power to stop It even if you all become hermits or stop consuming one way or the other. You are not even greedy consumers most of the time being that conscious of your impact. There is so much shit produced already that most of us could live with things which we already have, and kids in Congo could go back to being 3rd world country with no money coming from 1st world countries.
You might feel this way- but then your death will not improve anything. Like zero. World will not get one, even infinitesimally small point, better then what It was before your death. If It is a big deal for you then you might want to speak with other environmentally conscious people maybe this is a community wort exploring- some of them are total doomers so you might like them.
I think the thought you put into your impact on the well being of world is admirable <3 just be careful because world does not wish you death, It is just very indifferent.
