How can individuals improve their urban environment?

The message is that we need to take care of our city: we need to reduce damage, like driving our personal cars less, helping each other, thinking of our communities and neighbors. We can do a lot together, and we can save the world by taking care of our city and each other.

It's easy to walk 20 minutes instead of driving or taking a cab. So there are many ways to save our cities: we need to think about how to reduce emissions and avoid all the damage caused by our cars. It's by thinking about all this that we can help our cities.
