Yes that is a very nice explanation for getting rid of waste.

It also interesting to note that many animals use waste products as a defense. Besides some apes and monkeys, many reptiles, birds, and amphibians use waste products against predators. In fact birds that use waste products against predatory birds can kill their attackers because it eats away the waterproof covering of the feathers and bogs them down.
