damn... does this count? like generally we want to avoid plastic cups in the ocean, but would it be bad to take something like this from say, a hermit crab? if we take the cup where will it go? chances are it will just end up somewhere else it shouldn't, but this time without being made use of by crabs. my knee jerk reaction was to say animals using plastics don't count, but that's clearly not true when we reuse garbage intentionally to create animal habitat like artificial reefs. can we really say that only humans have the capacity to reuse their own garbage effectively?
