1)Big city has got many cars. It is bad for pulution and people.СCars make truffic flumes (its dangerous smoke for environment). And engines of cars make a lot of noise. My family have a car. Its a Jeep. We use it everyday, unfortunately(
2)In our planet live many people. In some contries people lack food. My family dont by too much food, because we know if we dont eat this food, it will spoil.
We waste a very small part of it.
