The environmental thing was 1 of the things on my checklist for switching to a straight. Water saving, money saving , cool factor, back to basics, etc etc.
I got a better shave out of it and increased my friend list. Which is the best part. I live in an area where I get to shake hands and chat with a small group of these fellows in here and sharing knowledge has been one of the best parts of this hobby for me. All good people restoring my faith in mankind.
As for the environment, in the end what the earth needs is a reduction in the human population for it to flourish again. I just hope it isn't anybody I know :<0)
