Now that michelle obama is back from spain, anyone know how much of a carbon footprint she left?

since they believe in global warming and carbon taxes, should the obmas go plant a few dozen trees personally and pay some sorta carbon tax to al gore? like that short helicopter flight barrack took the other day. didn't he tell the guys from detroit to drive down to DC and beg? now hes taking a helicopter to go a few blocks, he told us to watch our spending how long ago?
