Right back at you. The word moose encompasses males and females.  What mankind does to every species of animal on earth--including itself--is not just "nature" unless you subscribe to the kill everything into extinction theory of nature. 
And maybe that is man's theory of nature. After all, death is natural too. Next time you get ill - cancer, what have you - just let it go. No radiation, surgery, chemotherapy or other unnatural responses. It's just nature.
