Our subway uses a pulley-system to pull the vehicle to reduce the amount of air pollution. |

One of the problems in our present-day world is air pollution. This can be caused by vehicles that burn gas and release substances called Pollyciclic Aromatic Hydrocarbons otherwise known as (PAH's). PAH's can aid in the breakdown of the Ozone layer or even cause death to humans. |
One solution to this problem is to stop burning and wasting fossil fuels. If we do, the amount of pollution will decrease. Another solution often used by communities is to declare Ozone Action Days. People can ride bikes to their school if it's close enough or even just carpool. |
