Is the train the best choice for our enviroment?

The Global warming has been destroyed by all the humas in this entire world. We use resources that we actually don't need which increase carbon dioxide and other substances. Transportation is one of the reason of this problem, compared tov cars, plane, etc, trains release less carbon dioxide.

As we know plane can handle and carry many things and alot of people, but it release more carbon dixoide than the other means of transportation too. When the planes are up in the sky the amount of carbon dioxide increases. Cars are also the problem and many countries are still using the old cars which make more trouble to the enviroment. A research from a Swedish organisation shows that carbon dioxide releasing from news cars is equal to the old cars which were produce in the 17th century. Take a look at a train that releases only 7% of carbon dioxide per person in Sweden. You can see that even the trains release some carbon dioxide but it's still a good choice for our enviroment.

These problems can affect and transform life on the earth. At the same time there are a lot of researching that tries to help earth getting back to where it was.
