Very often when something breaks, we prefer to buy a new one instead of try to repair it. In some cases it is cheaper to buy a new smartphone or a new computer than to repair it and in addition we can get a new model. But do we really need to always have the last model with hundred of new features that at the end we do not really use or it is only a matter of fashion? The same applies also to cars, why do people love to change the car after only 2 or 3 years when we all know that a car can last 10 years without any problem? In my opinion, I think that when it is possible, we should try to extend the life of objects that we use in our life (like smartphones, computers, cars, clothes, shoes, etc) in order to reduce the pollution in the world. With a little effort we can help make the world cleaner.
