If someone goes on a hill or a high place and has a look at what is going on, down on the vast area, he will see a lot of curved lines that are like snakes, creeping in each other and there are some tiny objects that are moving like thousands of insects. Living in modern cities needs more traveling during the day because people go to different work places.
This is a good reason for having a liable transportation system that is able to transfer every body from one place to another one. Some people think that governments should pay attention to this matter and spend more money to build more roads and highways. They prefer fast cars and a good route to ride their vehicles because they have to work or shop and there is not enough time for all of them. I believe, governments should have a general view about transportation and it means that there are some other issues that must be considered at the same time.
If we spend more money on public transportation system, a lot of people can use it and they don't have to buy a car to pollute the environment and also we would not have so many car accidents that suffer a lot of families and are a waste of money, and time.
These days, every one is aware of air pollution and a great deal of damage to the environment that are caused by fuels. If the number of private vehicles increases, we can not breathe well. There are different diseases in children who live in polluted cities. Nature is changing and some areas in the world have had "acid rain" that destroyed a lot of trees in forests. Have you thought what would happen to our planet...
