Failing to reuse the plastic grocery bags?
Using more than one, ahem, "square"?
Putting those diapers in the electric dryer instead of hanging them on the porch railing to dry?

Having large families is an "eco-misdemeanor."
And don't think for a minute that it won't eventually be labeled a felony. Some countries have already used that one.
