Human Population Ecology : Resources Essay

946 words - 4 pages

In today's day and age, the world's human population is growing most rapidly reaching a striking 7.2 billion people and is expected to project to an astonishing 9.6 billion by 2050. According to the United Nations, population growth will spark in developing countries such as Africa, Afghanistan etc. However, questions and concerns are in the rise about whether or not the world will be able to sustain such a large amount of people. In years to come, there is expected to be a drastic decrease in basic essential resources such as food, water, and fuel in both developing and developed countries. When it comes to shortages in such resources overpopulation is definitely a main factor. Many problems and complications have already began to sprout and will undoubtedly worsen as they lead into the future.

Every person on the face of this planet knows that food is a very essential part of life. However, according to the Institute of Population Studies more than one billion people, go to bed hungry, not to mention the 25,000 people most of which are children, who die of malnutrition and hunger-related diseases. The issue of supplying the world's population with food is not an easy task especially when the population is growing. “The global food demand could double by 2050", says David Tilman, Reagents professor of Ecology in the University of Minnesota's College of Biological Sciences. In order to keep up with the demand, poor nations with their current practices will need agricultural land around 2.5 billion acres which is larger than the total area of the United States. Furthermore, evidence supported by the Food and Agriculture Organization of the United Nations, notes that food production must increase by 70% in order to feed the population by 2050, so the annual cereal production will need to increase by around 900 million tons, while the annual meat production needs to increase by 200 million tons to a startling 470 million tons.

Water is another resource that can be affected by overpopulation. According the Institute of Population Studies, around 1 billion people today do not have adequate water for drinking, agriculture or for sanitation. This is one of the major causes of death around the world. Population growth has threatened many people worldwide with severe water shortages if any access at all. This problem is a frustrating ongoing crisis. An example of this can be seen in Mexico. In the article, “Dry Taps in Mexico City: A Water Crisis Gets worse", by Ioan Grillo in the Times Newspaper addresses Mexico's water problem. In the main city, about five million people wake to dry taps. Often the streets in the neighborhoods reek of unflushed toilets, and children scoured the surrounding area for government trucks waiting to supply...
