The notion of anything being “disposable” is as preposterous as wasting something “just ‘cause”. We are an extremely destructive race. Or rather, the “advanced” members of our species are far more so than the less “developed” ones.
We should not leave a trail of destruction and depletion in our wake like a bunch of oafish cavemen. Like a locust plague unconcerned with it’s own continued existence past instant gratification. Stuck in an infinite loop of expansion and consumption for no other reason than to expand and consume. Such that the very notion of NOT expanding or consuming causes great revulsion.
