Not for that reason, but I do think that it's unethical right now because of overpopulation.
Whatever resources they consume are not going to impoverish anyone else. Maybe it would if they were being allocated on an international basis, but that's a silly thing to expect. (On the other hand, I do agree it is unethical in places like Egypt or Bangladesh).
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
