We live in a world where almost all of our actions have, somewhere, a negayive impact.

Wd usebplastic, wrong for ecology. We wear t-shirts, manufactured by poor people in China. We watch TV, whuch uses electricity bad for the environment. We drive i syead of walking, we eat non-sustainable stuff.

I could go on, and show how much of our "choices" are wrong and how, everyday, we "decide to make them".

So this boils down to either mental sanity or some kind of Amish life.
