Talk about fundamental change in the way people conduct their daily lives, look at what tiny, purposeful Ireland has been able to achieve in a very short amount of time.  From the NYTimes:

In 2002, Ireland
passed a tax on plastic bags; customers who want them must now pay 33
cents per bag at the register. There was an advertising awareness
campaign. And then something happened that was bigger than the sum of
these parts.

Within weeks, plastic bag use dropped 94 percent.
Within a year, nearly everyone had bought reusable cloth bags, keeping
them in offices and in the backs of cars. Plastic bags were not
outlawed, but carrying them became socially unacceptable — on a par
with wearing a fur coat or not cleaning up after one’s dog.
