I think Audubon certification is a big marketing BS.
If they were serious and trying to do good, they should not be using the name "Audubon". They have really nothing to do with the real "Audubon Society" and they are trying to con general public with their similar name usage.
Just because "Audubon" is not a trademarked name is no reason to abuse it.
I don't care if what they are actually doing is helping the environment or not. The fact that they are trying to fake out the general public enough for me to deride their whole operation.
