Helping the environment isn't just for grown-ups. We can all help and there are loads of easy ways that we can do our bit.

We all know that cars are bad for the environment. So walking is a much better idea - it's good for the planet and good for you. If you're too young to walk to school by yourself find out if your school has a 'walking bus' scheme.

A walking bus is where lots of children walk to school together, stopping and picking-up other children along the way. Walking buses are run by trained adults who walk at the front and the back making sure everyone is safe. Usually anyone on the walking bus will wear bright or reflective clothing to make sure they can be seen.

If your school hasn't got a walking bus yet - suggest one. Have a look at this website about schools in Hertfordshire who have walking buses for some ideas.
