Hoshi Shin’ichi is awesome. I feel like he deserves to be translated into English more than he currently is. He writes these great Sci-Fi short, short stories. This one is a sort of morality tale about the environment (and an increasingly relevant one).
First published in Japanese 1957 and available in the collection Bokko-chan in Japanese. Available here and there online: On someone’s blog here or there’s a weird scanned version here
