I wish I would have been able to enter, but I will still answer the question.

Like what @alchemage said i believe that it really comes down to education, but at the same time, they need the inspiration that empowers them to take action, inspiration comes from within, but is usually activated by an external experience that one sees which shows them that they could do the same thing and it sparks the focus to create the vision. I have learned recently that what you focus on becomes your reality, so if you want someone to make a difference, you need to get them to focus on their own ability to make a change through things that inspire them. For me that was permaculture!!!!!
