Humanity has been around for a very long time, but it’s only in a few centuries that we have grown to significant numbers and transformed our world in unprecedented ways (Brooke). It is likely that the world’s population will double by the year 2050. The increasingly large number of people who have become apart of the world population has created the problem of overpopulation. Human overpopulation is an unfavorable condition where the number of humans that depend on resources is significantly larger than the number of resources available to them (Population Connection). This situation can be seen in less developed countries due to the limited supplies available to them (Shah). Along with population growth come changes in our surroundings. This issue of human overpopulation is affecting the environment in many ways; it creates degradation in the environment, resources limitation, and a high cost of living.The history of human overpopulation leads back to A.D. 1, where the world population was at about 300 million and had continued to grow at a moderate rate. But after the start of the Industrial Revolution in the 18th century, living standards rose, and widespread famines were reduced in some regions. Population growth accelerated, from about 760 million in 1750 to 1 billion around 1800. World population growth accelerated again after World War II when the population of less developed countries began to grow (“Human Population: Population”). After millions of years of prolonged growth, the human population finally increased dramatically; a billion people were added between 1960 and 1975; another billion were added between 1975 and 1987. Human population entered the 20th century with 1.6 billion people and left the century with 6.1 billion (United Nations).For the last 50 years, world population increased more rapidly than ever before and will continue to grow in the future. In 1950, the world had 2.5 billion people, and in 2005, the world had 6.5 billion people. By 2050, this number could rise to more than 9 billion people (“Human Population: Population”). This rapid increase in the number of people is a major problem to the public. If the world population continued to grow at the current rate, the earth would not be able to sustain its people, and the number of people will decrease. Shortage of resources will become an issue in that there are not enough resources for distribution to everyone. The standard of living will also change due to the high cost of living. In less developed countries, many are dying because they didn’t have the fundamental resources such as water, food, and healthcare (Shah). It is no doubt that the planet is becoming overpopulated and the impact it’s making is something that the public needs to recognize.While many environmental activists acknowledge the issue, the rest of the public thinks that they will be able to overcome this crisis, as they were able to survive similar environmental events in the past. However, they did not realize that what occurs cannot go back to how it was before. Most people tend to focus on short-term goals rather than giving their full attention to environmental protection for long-term goals (Shah). For that reason, the planet is running out of resources, and with every child born, the environment suffers. It is necessary for people to understand that actions need to be taken to prepare for the impact that humans are soon to experience.Section I: Causes of Human OverpopulationIn the 1910s, the total number of people in the world was around 1 billion. A century later, in 2015, the global population count reached 7.3 billion. The number of people on this earth is growing at a fast pace. According to the United Nations, the world population could reach 9.7 billion by 2050 and over 11 billion by 2100 (Cumming). Almost all growth will take place in less developed regions, where today’s 5.3 billion people are expected to increase to 7.8 billion in 2050 (“Human Population: Future”). So why is there such a massive increase in population? How is this human population explosion possible? What is leading to this population growth?The causes of human overpopulation are complicated and influenced by many factors. The factors that have influenced overpopulation are interconnected, such as poverty and the lack of healthcare. The main factors affecting the growth of the population include the decline in death rate, migration, and poverty.Section II: Decline in Death RateThe reduced in mortality rate is one of the leading causes of human overpopulation. The population growth has increased as people are living longer. It is necessary to keep the overall birth rate and death rate in balance. If the number of children born each year does not equal the number of adults that die, then the population will not be stabilized. Human population multiplied during the Industrial Revolution, not because the birth rate increased, but because the death rate began to decline (“Human Population: Future”). In 1900, the annual mortality rate was one in 42 people. In 1998, the rate had dropped to one in 125 people. That’s a total decline of 67 percent (Francis).Medical advancement was perhaps the most significant reason why the balance has been permanently disturbed. With more discoveries in medical science, many of the once incurable conditions have cures today. Illnesses that had claimed thousands of lives till now were cured because of the invention of vaccines. The advances have eliminated dangerous viruses such as polio, smallpox, and measles (Renewable Resources Coalition). The improvement in fertility treatments has made it possible for more people to have children. It has become possible for couples who were unable to conceive to undergo fertility treatment methods and have their own babies. A regulated prenatal care has improved the chances of survival for both the mother and the baby during pregnancy. Furthermore, pregnancies are safer today due to modern techniques (Shah). As a result, the number of deaths is on the decline. While this can be beneficial in many ways, it also means that people are living longer than ever before. This change in the cycle of life and death has led to a huge population on earth, which will result in the problem of overpopulation.
