Demographic transition is the process in which a nation transitions from being a less industrialized society, with high birth and death rates, to an industrialized nation, with lower birth and death rates. Many countries have already been through this transition including the United States, England, and Canada.
The demographic transition to an industrialized society is detrimental for the environment because industrialized societies tend to use up nonrenewable resources and give off pollution. Industrialized nations have the largest ecological and carbon footprint relative to developing or nonindustrialized countries. Fortunately, there are some benefits to the process of demographic transition, including lower birth and death rates. Essentially, people in industrialized countries have fewer children and this in turn helps control the overall population size.
