Humans and the Environment Professors Bakus and Kiefer November 8, 2007 Population Control is Necessary in Protecting the Global Environment With the rate of the human population growing exponentially, there is no doubt that the increasing number of people on earth affects the environment. Unfortunately, few steps are being taken now to control population growth in many developing nations., where the growth rate is highest. Although the rate of population growth is slowing, more precaution must be exercised if we wish to preserve the natural resources that we are quickly depleting (Miller 10). Population control is necessary in protecting the global environment because the growing population depletes the earth of resources such as water, plant and animal habitats, and fossil fuels, as well as pollutes the environment. Although there are other factors that influence the health of the environment, they are all produced by humans or for human consumption. The growing population has increasing food and water needs. These human necessities cause destruction of natural habitats as well as change the composition of the land in many areas, affecting the native plant and animal communities that live there. Also, pollution caused by farming causes problems for nearby aquatic communities. Another major problem is growing cities, which disproportionately use resources and pollute the environment.

Background: Population growth rates and current environmental problems The world’s population is growing exponentially. Most of this growth can be attributed to the developing nations. However, due to the industrial revolution and the more recent technological revolution, urban growth is also very problematic. About 81 million people were added to the world’s population in the year 2006 (Miller 10). Along with this astounding rate of population growth must come economic and agricultural production to support these people. The need to support the growing population contributes to many of the environmental problems that are currently threatening the earth. Supporting the world population adds pollution to the environment and depletes natural and non-renewable resources. The pollution caused by cities and automobiles depletes the ozone layer, which means permanent damage to the earth’s atmosphere. Pollution of water sources and land is also a prevalent problem, which is sometimes caused by poor waste management and the large amounts of non-renewable resources that simply get thrown away. Deforestation of land is another environmental problem, which is caused by the need to make room for more farmland for food, or in order to use the lumber of trees to build for people. These environmental problems are widely recognized and accepted as major threats to the earth and its natural resources, most of which take too much time to replenish. Humans are simply depleting the earth of its major resources and destroying habitats too fast for nature to react or replace them.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
