That is my suggestion, correct.
Rights are given by man, some rights are considered natural/inalienable by many societies. Even those do not exist in practice without a society to support the idea.
We give animals rights(so to speak, ex: animal rights groups, endangered species), but not bugs, not plants not bacteria or fungi(certain cases of the previously mentioned may be on an endangered species list. They however get little attention, even though they are all critical parts of ecosystems). Society as a whole does not back the idea wholeheartedly of giving all living things equal rights.
I suppose another way of saying it is: rights are only given to things people decide they should care about for some reason.
