This family, apparently, because this is a routine occurrence in their household. You’d think they’d have learned after the twelfth or thirteenth time it happened, but nope! :P
Yeah, the problem is less having it at all, it’s more evenly distributing it across the planet after it’s been excreted, so that there’s never too much piling up in any one place. But as so much of it is produced at a time on a daily basis, and it also presents health and other contamination concerns should it ever get where it’s not supposed to…it’s easier said than done.
It can also be argued that a planet could have too much of a species producing too much waste at a time than the planet could ever reasonably handle…but that’s a much deeper and more complex problem.
