1) How is population change modeled and explained?

2) Why and how do governments promote population change?

3) What are the effects of population change on resources and the environment?

1.  Population change is modeled and explained in a model that shows natural growth or anexponential growth model. This comes along with the changes in population size and agedistribution within the population

2.  Governments may promote population change in many ways. One way is to limit the number of children citizens can have. An example of this was China’s One-Child Policy, a law where the Han Chinese (primarily living in urban areas) cannot have more than one child. This drastically affected China’s population as now there is a huge male and elderly population. Another way is to push for the usage of contraception. In Iran, contraceptives have been used more and have been endorsed by the government to limit an unbalanced population.

3. One environmental effect of human population growth is the problem of global warming. Some people are scared  that global warming will lead to rising sea levels and extreme weather conditions in the future. another is deforestation,  in order to support the growing population, forests are being destroyed at an alarming rate.
