An MSN article about travel caught my eye earlier today. It mentions, among other things, that there is now a program, albeit largely symbolic, where by making a donation, you can "offset" the impact of your flight on the environment. It also says The Dave Matthews Band, too, has decided to offset the carbon emissions caused by its tours going back to 1991. There is no mention of the fact that this is the group that dumped its raw sewage into the Chicago River.
