I saw a news article about green cars which caught my interest.

Initially, I thought green cars were simply cars painted green. After extensive research, I discovered they are actually eco-friendly vehicles.

Green cars contribute to a cleaner environment by not polluting the air, thus helping to keep the earth clean.

In the future, I believe that everyone will be driving a green car as people become more aware of the dangers of air pollution.

Green cars have the potential to keep our planet clean. Whereas in the past we polluted the air, now we are working towards a cleaner earth.
