If I could change the world

If I could change the world , I´d like to solve the problems about violence, pollution, poverty, prejudice. These are big problems so I would have to start with simple actions to solve them. For example, doing voluntary work, being honest, helping to protect nature, making donations. Besides, I´d ask for my friends and family to help me.
In my everyday life, I don´t fight or pollute and I´m generous but I have to do more, everybody has.
