I draw your attention to neo-Paganism, a contemporary religious movement which also includes reincarnation as a human being on Earth as one of many things one can do after death, maybe. This means that each lifetime is an investment in the future. By our acts of will we throw our weight behind probability lines that seem to lead towards a type of future world in which we d like to take rebirth as a carbon based life form. We can let it all go to hell and suffer through billions of lifetimes as microorganisms and aesthetically unpleasant frightened creatures. If we re lucky, it might only take four billion years or so to develop a brain that can tell a joke.
Religion is important because it informs our actions.
Of course, this is only true for individuals who actually practice their religions, even when they are alone. Faiths that teach that this is your only life on Earth offer no theological reason to save some for later, and its practitioners behave accordingly. The neo-Pagan faiths offer just such a theological reason, several, in fact. Our commitment to and love for the Earth and the community of living things to which we belong informs our lives and propels us towards sustainability. Which brings me to the inquiry about human rights.
