A lot of families own or use a car. But there are times where it isn't really necessary to use it. For example if you have to go to the store just down the street, you really don't need to drive there. If you really don't want to walk short distances, riding a bike is also a better alternative for driving. Try to encourage others to use less pollution by walking, running, or biking places. This doesn't meant that you should never use your car but if you and your friends are all going to the same place then you should work out a carpool arrangement to decrease the amount of transportation pollution in the air.

I totally agree with you Christina, use less energy using items such as cars and switch to just bicycling or walking.  Good Job!

Christina what do you think could be an alternative to flying, and driving very long distances?

I agree more people should use bikes instead of cars.

This is so true Christina. When I am going to the same place as a friend we try to car pool.

I agree if you and your friends are going to the same place carpool.

Gracie, examples where you would have to carpool would be sports, and to and from school.

William, the only alternative to flying would be to just limit the amount of flights you take for unnecessary trips.

I agree, bikes is a good way to move in the city but some cities don´t have roads to bikes.

I am agree wih you. We don't really need to dive everywhere, we can go walking instead of driving , or we can use bikes too.

I agree with you, I think that car is a need because if you are late or you don't have much time this is faster than walking or riding a bike, but it' very polluting too.                                                                        if you have to do short distaces, walk or ride a bike is confortable, healthy and you don't have a big foodprint.
