It’s not easy to get involved in large scale when we didn’t have the knowledge and decision-making position to act on a large scale, but this doesn’t mean you can’t have impact on solutions.
Why get involved if our influence is so weak? Like everything, when there is doubt that it can be resolved, we must take the bull by the horns and act. Even if your actions are very small scales, they have an impact on your immediate environment and perhaps you will influence someone else to do the same thing as you.
