This makes me think of a solution to climate change. I.E. if 3.5% of the world population starts living their life in a deliberately sustainable manner, we reach a tipping point and the rest of the world will be more accepting of legislation and changes to their lifestyle. I know within my circle of acquaintances we are at 3.5%, but maybe around 2%, but growing. I do make an attempt, but I could do more to live sustainably. Articles like this make a strong argument for joining the cause.
