Cars

Although cars are an important part of everyday life for a lot of people, they also cause a lot of pollution and release a lot of greenhouse gases. You can save a lot of energy by using buses or trains and by cycling or walking whenever you can. If you have to use a car, try to make sure it is full. Four people in two cars is twice as bad for the environment as four people in one car. If you know people who need to get to the same place as you, why not give them a lift?
