What is your definition of a 'Greenie'?

[Lilith7]

I think it describes someone who's aware of the problems we face with regard to our environment around the world & who tries to as best they can, live without causing further damage & do a bit of repair work here & there as they go. And even if that's only in a small way, every little bit helps.

Planting more trees makes good sense & some efforts at regenerating the Great Barrier reef do seem to be working, but we do need to do more.
