This is a tiny example of the Falkland Islands presented by Eric Reguly, but a valid one,   Admittedly,we do contribute to some degree to the world's environmental effect, but we do not on the other hand control the global climate switch, and that is what the environmentalists foolishly refuse to acknowledge.    The climate of the earth has been changing for millions of years and those changes are far beyond our control.    By all means improve our lifestyle, but don't screw it up on the other hand by introducing silly controls which have realistically no impact on the World's climate.
