In it, he hits the nail on the head when he admits the law is merely symbolic. But what's more important is how the backlash has highlighted the unwillingness of many Londoner's to fully grasp the situation we're in.
"... if we're so hostile to making such a simple change in our lives, how on earth are we ever going to make the myriad other changes -- everything from how we consume energy to where we buy our produce and dispose our waste -- that are so desperately needed to repair the environment?
If we can't do something as simple and logical as shutting off our vehicle shortly after it stops moving, if we're so selfish, spoiled, unthinking, uncaring and inconsiderate that we resist making even the most minor changes to our precious lifestyle, then our chances of saving the planet from global warming are pretty much doomed.
And so, of course, are we."
Change is never easy, but it's got to start somewhere. Hopefully the debate this bylaw has created will underscore the need for Londoner's to start taking some baby-steps.
