"In perhaps his most influential civil rights era song, Bob Dylan asked senators and congressmen to 'please heed the call.' Of course, help from those in power makes it easier to address any major societal issue. But Dylan went on to warn these leaders: 'Don't stand in the doorway, don't block up the hall.' His sage advice to allow other contributions is now as relevant as ever. We must prevent catastrophic climate change, our societal challenge akin to those Dylan was 'singing' about and King was meeting. We can do it, but only with new thinking, thinking that is currently shackled by the status-quo."
