Air Pollution

Our world is at risk especially because of global warming, and one of these causes is pollution.
Factories and cars are the most polluting of all. They send a huge amount of carbon monoxide, methane and carbon dioxide to the atmosphere, which is very harmful to the environment.
The ideal solution to solve this problem is the reduction of personal transports (cars, motorcycles) and the adoption of public ones (bus, train, subway), the use of bicycles and even to opt for using “eco-friendly” fuel.
Everyone can do things to help the planet Earth, and two of these thing, that I think we are apt to do is to pollute less, to opt for using public transports and most important of all, and which doesn’t cost a thing is to spread the word to make the other people act like we do, thus helping save the environment!
