Because they have no (or not enough) fresh water for their requirements. We humans can't drink sea water, and because of its level of saltiness, it can't easily be carried through household plumbing as the salt is (a) very corrosive, and (be) liable to clog the pipes if the water were to evaporate in hot weather.
