I've been writing up a draft for the petition. I'll post it here - there's a place here that's perfect for temporary files for review by invitation only. I'll get it to group leaders before posting it at change.org
I've been checking out what environment related petition got only a few hundred and compared them to those that got 20,000 or more.
I think we the purpose of the petition should be a reversal of the amendment the outgoing BOC voted in.
