In Michigan we have had $0.10 deposit on beer bottles and pop(soda) bottles for a long time. It appears to extremely successful. You never see bottles littered anywhere, they are always picked up by someone in need.
Gas station garbage can a frequently sorted through for returnables.
School programs like band and sports teams will have bottle drives where they send the kids around through the neighborhood and collect bottles. It is a very successful fundraising method for them.
I wonder is the drop in car accident death caused by;
1) Cash for clunkers taking old dangerous cars off the road so the fleet consists of more newer safer cars
or;
2) People driving less since the recession and the gas price increases
It reminds me a lot of the app "Circa" on iOS. IT the same sort of snippets for news. An interesting way to display research. Also, really nice looking.
When it asks for permision there is a spot for who can see the posts. I always choose "Only Me" and I deselect the post to timeline request as much as possible.
