Conservationist edit
I am a conservationist and a nihilist:
(a) Conservationist: our environment nurtures us and I enjoy it. Therefore, I work to protect it.
(b) Nihilist: there is no inherent value, meaning, purpose or morality to life. You can choose to suicide or do ugly things; I choose beauty and life because (1) I enjoy them and (2) I am biologically wired to enjoy them.
