To sustain or not to sustain?

I am a member of The Designers Accord. An good organisation that gathers do gooders / good doers from all over the world :o)
I want to share some simple and witty (yet very TRUE) responses from TDA's online survey. Of course there are other great [and technical] ideas but these are the one that grabbed my attention :
WHAT 'S YOUR GREATEST SUSTAINABILITY CHALLENGE?
- Removing plastic from my life.
- Cost.
- Food packaging. In the supermarket, everything I eat is packed at least twice.
- Not using the latest material just because it is sustainable. Just use less.
- Getting middle America to actually get it!
- Depression over how much there is to do — I’m tired!
- Quoting Daniel Hebert-Moto: “it’s complicated stuff”
- Eco-friendly materials are too expensive!
- Affording it. Sustainable solutions needs to be the most economical in order to be adopted (and should be eventually).
- Training people to design and make furniture while questioning whether the world really needs any more furniture.
- Convincing people that we have spent the past 50 years making a mess, and should now spend 50 years cleaning it up.

Speaking of which, I would like to present the latest addition to toil's family - GO GWEEN!!
