Population Growth and Pollution
Over the last many years, there has been a massive depletion the earth’s resources and this problem has been closely associated with the increase of human population. For several thousand years, people lived harmoniously with their environment. The sizes of population were small and the tools meant for supporting life were relatively simple. The energy required for working was directly provided by the concerned worker and the various animals around him. However, since the middle of the seventeenth century, there was a drastic rise in the number of human population. Problems associated with overcrowding are multiplied as a large group of people are added to the population of the world every year.
This booming population usually concentrated on the urban parts of the world. Currently, many cities have several thousands of inhabitants. The developing and less developed nations like Latin America, Africa, and Asia are dotted with several thousands of these cities that are overpopulated. This is primarily because a lathe number of people leave their rural lands to get proper food, shelter, and employment. In fact, there are also several farmers who have been compelled to leave the land because of the increasing problems of famine and drought.
However, as people start congregating in the cities and towns, there is an alarming rise in the level of environmental pollution. These adverse effects were first observed in the Middle Ages when people used to throw most of their garbage in the canals and the streets. Eventually, this problem took a bigger shape and soon started affecting a large chunk of the population.
While discussing population growth and pollution, we should note that there are several factories and transportation units that primarily rely on fuel. Several billion tons of oil and coal are consumed throughout the length and breadth of the world. As the fuels burn they lead to the formation of smoke and other partially visible bi-products in the air. Even though the rain and the wind can often wash this smoke emitted from the automobiles, factories and power plants- the cumulative effect that it comes down to, poses a great threat both for the environment and the humans.
In several places, the smoke emitted from the cars and the factories naturally combine to form smog and fog. For many centuries, London in England has been subjected to this immense danger from the smog. This is a potential cause of death, particularly for elderly individuals and other people who suffer from severe respiratory issues. This air pollution resulted from the consistent use of heating fuels. The problem has now expanded, and it is not merely confined to London.
Several big and small cities across the globe experience this rising threat from air pollution. As the smoke is emitted from the factories and automobiles that make people’s life easier and help them to sustain- it can be said that overpopulation is one of the central causes of this issue. As more and more people flock to the cities, there is a growing demand for jobs. To meet this demand, factories and industries hire people. As a result, the environment is subjected to the threats of pollution.
Most of the scientists are under the conviction that almost all cities with a population level more than 50,000 have a significant degree of air pollution. By burning garbage in an open dump, or pushing off garbage anywhere down the roads, more and more people lead to increasing pollution. To meet the increasing demand of jobs, the factories employ people, and it is these very factories that eventually emit deadly gasses from electric power plants and other noxious gasses like sulfur dioxide. The factories at the industrial boilers also send in massive amounts of smoke into the air. Again, the procedure of generating steel and plastic, plays a vital role in increasing the amount of smoke. This smoke often contains metal dust or other microscopic elements that are made of deadly chemicals.
Overpopulation not only affects the air but also affects the quality of water. As more and more resources are depleted, the lives of several thousands of humans are at great risk. Therefore, proper measures should be adopted to control the highly increasing population rates.
Countries, Cities, and Individuals fight back against pollution in several ways. Pollution is deeply involved with Politics. Just look at this article in the NY times . Individuals in the United States have access to the legal system to fight pollution whatever the form. Some states allow a citizen to sue as a “private attorney general” and bring cases tthatcan benefit many people. Other people bring cases again specific types of individual pollution such as benzene exposure causing cancer. Countries tend to become more involved with Treaties or other agreements. Here is a list of historical pollution related treaties,
