I like this recent post by Leo Babauta of Zen Habits.
Particularly his use of the word earthling.
I like to think of myself as an earthling (though it's maybe a bit cutesy).
Perhaps earth being rather than human being?
Makes me feel part of something so much bigger than myself, and human beings seem to come in for so much stick these days - you know, despoiling the planet, war-like and agressive, thinking we are superior to the rest of nature etc
As an earth being I am a miniscule part of the whole ecosystem.. the whole solar system..awestruck and full of wonder, and doing the best I can.
