Eddie,

It's a real simple formula. The higher your consumption the more impact you have on the environment. So baseline how the avg. world citizen lives vs yourself. How mauch change would you have to effect in your life to be that average citizen. Are your personal environmental polices bringing your consumption down to below that avg.? If not you have some work to do to call your self an environmentalist in your own life let alone in soicety.

I would bet you that the amount of chemicals involved in just the food in your home right now is more than that involved in the avg. citizens of the worlds entire yearly supply. Even if you shop organic.
