The government should be concerned about rapid population growth because it could lead to things like, food shortage, unemployment numbers increasing, the homeless numbers increasing, even an increase in disease
The government should help the citizens start their lives as in providing basic education through taxes and helping those who have hit hard times and need a little assistance, however with a bigger population and an increasing one as well the money supply to do such things is going to wear thin and make taxes go up or they stop doing such services
With too big of a population our carbon footprint could break down the O zone layer rapidly and cause the suns rays to be able to reach us and possibly cause cancer, we take up more room meaning less room for nature and we eat more so less animals and could cause extinction of certain animals climate will continue to increase
The government can put in rules about how much land can be used or how it is used keep companies from tearing down forests and make them government nations parks to reserve nature, get the people using more renewable resources instead of nonrenewable
The government should not be in citizens family related issues as in how many children they should have, when they should have them... etc however I do believe that before having children parents should be educated about the pregnancy process all that is to come ...etc BUT this all could be done through a DOCTOR who is the parents physician and not by government
