I thought this chapter was very interesting. Since earth’s population is growing to the number of 6 billion, food and resource demands are also increasing. How are we going to feed all of these people? Resource depletion and environmental degradation are currently undergoing demands as well for this growing population. The sections in this chapter include discussions about: Society’s Four Transitional Stages, Evidence for Negative Population Growth, Future Food/Supply Demand Balance, Protecting the Environment, and The Challenges Ahead.
Society’s Four Transitional Stages:The United Nations’ low/medium population projection suggests that food supply growth will continue to outpace food demand supply growth will continue to outpace food demand growth, resulting in continuing decline in real prices for farmers. (McKinney, 57). This section discussed the four transitions of societies based on
demographics,
economics,
agricultural productivity, and technological advancements (
technology). There are many different sides to each argument. If income growth and population growth slow down, food demands decrease as well.
Evidence for Negative Population Growth:This section was difficult for me to understand since it deals with various countries' statistics. The United Nations' medium population projection of 2.1 children after 2040 is widely used as a demographic forecast, but it unrealistically assumes that this rate will be the same in both developed and developing countries. (McKinney, 56). We cannot base our future statistics on predictions based on past and present population rates. There are many variables that change such as population growth/decline that are not always predictable.
Future Food/Supply Demand Balance:If population and income continue to grow at the same rate as they grow from 1995 to 2000, the demand for food will sharply outgrow future food supply. (McKinney, 57). This is a very scary thing to think about. Some differences have been made. Many statistics show that birthrates are decreasing causing more available resources. What about the families that aren't decreasing family size? Do they know that our resources are limited?
Protecting the Environment:This section describes the consequences of population growth. I thought that it was mind blowing that population growth leads to land clearing leads to streams being polluted and lower quality air. Education may promote the awareness of the environment possibly changing the behaviors of people. Forests are continually being cut down for the resources it provides. Something that a lot of people don't realize is that this affects the species living within the environment as well.
The Challenges Ahead:I interpreted this section to be based on balance. If you balance population, the resources provided, and the food supply, it will work more efficiently. If one of the aspects such as population, the whole equation falls to pieces. Other things to keep in mind are trading, food businesses, and agriculture. The book explains that agricultural trade in a mature society remains high to supply the diversity of food products demanded by high-income consumers.
Christen's Views:I thought this section was a little difficult to understand, but realize that we are about to face challenges is we don't readjust our behaviors. I think that with some education on the topic, people will have a better understanding of everyday choices that are overlooked. When planning families, people may consider these facts and readjust their decisions.
