But is Al Gore still the right person to serve as the foremost face and voice of this movement? Some say he hasn't sustained his momentum or succeeded in bringing about big changes that are needed. Beattie wrote in an e-mail, "Trust seems to me to be one of the most fundamental issues here in people trying to change their everyday habits at some personal cost, for a greener and more sustainable future. A leader who cannot really be trusted, because of his own lifestyle, would be, in my view, a bit of an obstacle."
