Few would dispute the fact that cars have a huge role in our lives. If it wasn´t for them we wouldn´t have the living conditions we have now. However, we have to be aware of how they affect the environment and also, of how to use them in the better way for the enviroment.

The time is one of the most important things in the world. It is something that we can´t get it back. And cars have made that we have more time for our personal moments, as we need less time to arrive in the places that we want to. Also, over the period they have improved a lot, getting more and more comforts and security too.

Nevertheless, we must remember how pollutants they are. We should think first for what we want to use it for and if there are alternatives less pollutants. One way to do it, is trying to go more than one person in the car when all of you are going to the same place. This way, instead of using, for example, five cars, you are using only one. Other option is to compare how much time do you spend going to your arrival using other kind of transport instead of your car. However, I think that the different ways to try to be respectful towards the environment are a personal reflection and if we are not mature enough, then, law should be act.

In conlusion, it is indubitable that cars have made our lives easier but we have to take care on how we use them.
