objectively, a "should" is impossible because the world, the universe, etc. have no concept of things "needing" to exist. the opinion that us hurting the environment is an opinion. the environment is incapable of feeling anything about it. the emotional value of nature is entirely a human creation. also, technically, we are natural, and our behaviors are natural. i dont get why we exclude human behaviors as a part of nature. why does building a civilization mean youre not natural? a manmade skyscraper is as natural of a component of a species development as a beavers dam. its creating shelter and utilities with the materials you have. were as much of a part of the life cycle as anything else, and even if were killing things on this planet, the planet doesnt really care. we could wipe every living thing out, including ourselves, in a giant explosion, and the planet would revitalize itself over more time. the only thing that will really kill our planet is the eventual death of the sun. we are not stronger than the earth, we are not killing it. were the only species we know of that can even consider our own behavior needless or destructive. its ironic how the result of a more complex psyche has only caused the majority of us to hate ourselves for our natural progression and social operations.
the planet doesnt care if something should or not. were simply a part of the life cycle. if we kill things, their energy is recycled. it doesnt really matter. id say "we should exist to continue the flow of energy in the universe" but itd flow whether we were here or not. because theres no natural concept of whether or not something "should" exist in the broad span of things, i cant really answer the question with a yes or a no.
i can, however, answer what i WANT. do i want humans to exist as a species? sort of. i think theres a beauty to our complex psyche, and im personally glad it allows us to feel appreciation and perceive beauty of our ecosystem, and i like preserving it because i can perceive that beauty myself. there are times i like being human, and i appreciate our culture and our history. i enjoy the existence of the human race. i even find a beauty in the horrors committed by mankind. yes, its horrible, but i think the fact that i can feel that way about something is beautiful as well! i find the natural progression and history of humans wonderful, and im interested to see what happens next. i cant really say i loathe or regret our existence for those very reasons.
this is like some giant ass ****post what the hell. tfw u sit back and look at what you wrote and think wow, that was unnecessary. i hope someone got something out of that mess
