first, there is no ethical way all of the humans on the planet can die, there's no way you could convince 8 billion people to stop having kids, and enforcing reproduction rights is definitely wrong, you also couldn't convince people of a mass suicide, so humans dying out as a species is not an option.

i would also like to clarify that i do not support capitalism in any way (i am very socialist) and that I'm applying value to useful things, not things with monetary value, if earth for some reason didn't have any metal deposits on its surface anywhere, and all of the useful materiel was deep enough that you would need metal to access it we would never have gotten this far, and if civilization did collapse there would be no returning to what we have now its not about capitalism its about the actual materiel that would be impossible to access or use.

and yeas i do have pride in being human, and you should too! name any other species on earth that has walked on the moon, or invented philosophy, or even complex meaningful language, humans (as far as we know right now) are the only things in the universe that are trying to understand the universe, I'm definitely not saying i condone animal abuse or pollution, or the oil industry, but if those things went away right now everything would be a lot worse than it is.

sorry for being so long winded! I'm just a nerd for this stuff!
