Tracy Crawford from the Green Bay in the U.S is a Conservationist and normally drives around in a Prius, which she gets around 50mpg but that is still not good enough for the environmentalist.

She has now given herself a challenge to go without petrol for a whole year. She is now selling her hybrid Prius and is intent on doing this, but she knows that it will be hard.
