Can films save the world

I do believe films can change the world, but saving it is another story. In films we see that people can be motivated and give people ideas to help save the world but so few really choose to make the commitment to save it.

This is why I think that film can change to world by bringing up pressing matters and major world problems. Although with film people take a film in a different way and with the different perspective's can help in many different ways so I agree with this but don't at the same time.
