Have you spoken to people in your life/work about this. Words are cheap and most people will agree but they still continue to buy from Amazon, they still shop from food places that import foods, they still buy the newest cars.

But you are right that social change isn't impossible and more and more people are becoming aware that they must make personal change.

I disagree that politicians are incapable of doing good, I'm not in america so things are different not to say they're all good but there are MPs that try like my local, she's helping me in setting up community gardens.
