I just heard of my mother yesterday while she was watching TV that "do your best to take your children away from this city and let them breathe the clean air; that's the least you can do to keep them alive". Wondering about what she had just told me I found out that she was absolutely right. Pollution and traffic have made the residents of big cities vulnerable to so many problems. Perhaps I could save my family from the monsters, but would it be the best solution to cope with the mentioned problems. I would undoubtedly say "NO". First and most importantly, respective authorities should improve the quality of the petrol we use. Certainly most people know that when the petrol used in cars is of low quality it would not be burned completely and car engines would release lots of poisonous gases into the atmosphere. It may even be concluded that-although not sure whether it is scientifically proven- it is not the amount of petrol used which leads to more pollution but whether it is burned efficiently or not. Not to mention that there are some elements such as lead which can be removed from the petrol to make it less hazardous; unleaded fuel I mean. The second remedy is to keep all factories and industries even the smaller ones away from cities. Apparently a significant part of the pollution is the result of the activity of some factories constructed too close to the cities. Whatever is emitted from these factories goes directly into the cities. Although the activity of these factories is essential for the economy, the problem they create by making the air less clean is not something to be neglected. Therefore, they have to be constructed farther afield.
Still another measure which can be taken is to reconstruct and redesign some streets and highways. This
