If people migrate to cities, they become more overcrowded and so always more people will take cars to go to work and as a result traffic congestions will rise sharply.
A good idea would be to increase the number of public buses in the first hours of the day.
By doing this many people will prefer to use public transportation to go to work and traffic congestions will decrease.
People spend too much time watching TV.
For example some studies demonstrate that children spend around 5 to 6 hours a day watching tv programs.
Consequently they don't have enough time to do their homeworks and to socialize whit their friends.
If parents will be more restrictive about use of TV and organize to their children alternative activities then this problem could be easily overcome.
This will lead to minor use of tv from children and that will also strenghten the bounds with their parent.
The development of tourism often create resentment among local people because tourists do not respect their traditions and their culture.
For example some south american tribù don't want that tourists take picture of them because of religion beliefs.
The obvious answer is to explain tourists this cultural belief and to control more strictly that they rispect this rule.
Furthermore this measure could garantee a better coexistence between tourists and local tribù.
