By definition, without the layman embracing sustainability, it is only a feel-good exercise. 1 person is insignificant, 1 billion people can make a difference. Don’t get me wrong, it all starts with the individual, but there needs to be meaning for a lot of individuals to have impact. And again, without quantifing the outcomes, you will only have faith. While that works well with religion, it is an albatross for the green movement.
