As we know get around the world is easier than before because nowadays we use cars, airplanes, buses, trains, etc. It goes fast and we arrive just in hours to places far away.

But, if we compare the actual transportation than before, we can notice a very big differences.
First,  people used to move walking, riding horses or donkies, carriage, etc. And the faster one was train wich was  the unique that makes pollution. In a contrast, nowadays the pollution is a big problem because of cars and airplanes which damage the enviroment.  Coupled with this, the traffic is a waste of time, energy and indeed we make more dush a diference than before, it didn't exist, so people had more time to do their things on time; not to mention that,  there used to be the sense of socialisim when people used to talk to others, have fun and make new friends while the person in traveling on his/her journey.

Is interesting to know that at the present time there are people who want to help in the global warming issure; although it may be difficult, because we need people learning what is the best way to travel without making much pollution. 

Then, after all the points  we can compare, is good if we travel how people used to do years back. It will become easier when more people give an opportunity  to live in this way using trains, bicycle, or both for travel, or at least try to avoid the much use of plains and particular car. In the same manner, we are helping to save the world.
