WHICH IS THE SIMILARITY BETWEEN TRANSPORTS AND THE SCHOOL?

Imagine a world without cars. Suddenly, it might seem that  a few great upsides associated with cars (the fast transport, the easier transport for people, etc) would vanish. But it would cease to consume the oil and it would reduce the pollution in all of the world (including the school).

We think it's better if we only come to school by foot because if we remove all the cars that go to school, it will reduce a lot of pollution, and we will have a better school.

If it is not possible to come to school by foot because it is a long trip, we think it is better to use electric cars.
