Nowadays, pollution is one of the most talked about and important problems in the world. Some years ago, some people didn’t know about it completely. Nevertheless, today it is unquestionable. Pollution in cities, caused mostly by car emissions, is becoming bigger and bigger.



On the one hand, our lifestyle has changed. Some years ago life was very different. Our cities are full of pollution and it's very difficult to change this because... would you give up things like using a car? Most people don’t. In addition, our main energy source is oil. Petroleum is extremely polluting and the worst thing is that we use it every day. Because of all this, we know that it is very difficult to eliminate pollution in cities.



On the other hand, If no one initiates the change, it will never happen. There are many people who have already begun to change their habits to help the planet. They do simple things like not using the car so much and going walking to work. Besides, these actions may seem small but they help a lot. In addition, eliminating the use of cars or reducing it as much as possible is difficult but not impossible. In a city like Granada, it is even more probable because there are many types of public transport such as the tube or bus and you can use them instead of your car.



All in all, making a city like Granada a place without cars is very difficult, but we should try it. In my opinion, important people like the city hall should try to put measures to decrease  car traffic.
