From personal experience I can say "picturing trash" works. I remember a few years ago when attending a local concert venue I was appalled at the level of waste generated as I watched trash containers overflowing with recyclable materials.
So I snapped pictures and posted on line.
The results?
A member of the PR team for the venue contacted me and I explained it didn't have to be just one way. The next season this venue began actively encouraging recycling at their facility. And they gained a super loyal customer as a result.
I am happy to see someone else taking a bold step as well in this area to create positive new patterns of behavior.
Everything has to be on the table if we are going to successfully make the leap to the next.
