how to reduce the city present population?

our modern city is too crowded， and to solve the problem， three proposals are put forward. most people believe that we should fist practise the policy “late marriage” and “one couple， one child” in order to reduce the birth rate. secondly， the city government must have a tight control over rural people entering cities to engage themselves in trade or do various physical jobs so as to lessen the pressure on the city caused by the increased population. finally more and more people suggest that living blocks with shopping centers， schools， hospitals as well as cinemas and theatres round them or even satellite towns should be built in city suburbs or the countryside round the cities. in this way city citizens will be encouraged to move there to live and work. if these three proposals are well carried out， the city population will be greatly reduced.
