It sounds good, but its not that effective. More effective would be to reduce the number of things produced by industry, especially those we don’t really need. It can be done simply by people not buying them. The problem to overcome is to get people to agree what not to buy. If you can get them not to eat beef for a week, you can get them not to buy something for a week, particularly if you start with something small, such as a DVD. In due course you can both extend the time and also the choice of what not to buy.
