In the United States, the Friday after Thanksgiving is a traditional shopping orgy -- and so it has been adopted by a group of folks calling themselves "culture jammers" as Buy Nothing Day.
This year, Buy Nothing Day is November 25, and is recognized internationally.
Now there is always a lot of talk about buying green -- green processes, green ingredients -- but it is always talk of buying. Consuming green is far better than the alternative. But in the end it is consuming, using resources. Remember the old saying "reduce, reuse, recycle?" This is the "reduce" part of the equation. Sort of a "conservation of shopping."
We Americans, even greenie Americans, use more resources than almost anybody. For an example, try one of several ecological footprint websites:
Best Foot Forward
and More . These footprinters are aproximations, but point out the consumption issue.
In the end then, on Thursday, November 25 practice one day of lowered consumption. Just one day. You can do that, right?
