As Sierra Club President, Werbach attempted to capitalize on his youthfulness while continuing the political activism of the organization. The membership has grown to 600,000 and the average member age has fallen from forty-seven to thirty-seven. Werbach has also worked to recruit a new generation of activists by spreading the Sierra Club's message via popular music and the Internet.
Werbach is often considered one of the most influential people of his generation. Vice President Al Gore remarked, "Adam Werbach is proving what many of us have believed all along. Young people do care, they are involved, and they are already making a difference." When Werbach is asked if his age disadvantages him, he replies, "Yes, I'm much too old for this job. I was a far better activist when I was eighteen."
Adam Werbach is the final speaker in the Athenaeum series Global Environmental Issues sponsored by the Roberts Environmental Center.
