For example, it is the second largest per capita importer of protein in the world, and it imports 63 percent of its cereals, including 100 percent of its corn and rice. As noted earlier, the services of capital and labor do not explain economic growth in its entirety. While total food calorie production increases more under population growth than under income or technical change, the per-capita values decrease below the values of all other impacts. Besides, students are not supposed to get creative here Read more>> Encouraging that trend hardly seems wise. Moreover, it is often assumed that population size and per capita impact are independent variables, when in fact they are not. As the population increases, the demand for food can only grow bigger. The world is growing at an amazing rate. For instance, it is easy to mistake changes in the composition of resource demand or environmental impact for absolute per capita increases, and thus to underestimate the role of the population multiplier. The most important way to combat a steady rise in the population is education and empowerment. The MAHB Blog is a venture of the Millennium Alliance for Humanity and the Biosphere. The angles from which you can approach this problem are almost endless. By Antonia Čirjak on May 3 2020 in World Facts. Five hundred people may be able to live around a lake and dump their raw sewage into the lake, and the natural systems of the lake will be able to break down the sewage and keep the lake from undergoing rapid ecological change. Nor is there any reason to believe that modern medicine has made widespread plague impossible (21). The third individual partial impact relates to the effect of population growth on food demand. It is abundantly clear that the entire context in which we view the world resource pool and the relationships between developed and underdeveloped countries must be changed, if we are to have any hope of achieving a stable and prosperous existence for all human beings. The first is that man’s pre-1940 environmental impact was innocuous and, without changes for the worse in technology, would have remained innocuous even at a much larger population size. Not mentioned here are the effects of global warming, which will surely worsen due to the increased carbon footprint. Contraception is when you intentionally want to stop pregnancy. First, population growth and the aggravation of distribution problems are correlated—part of the increase will surely be absorbed in urban areas that can least afford the growth. A great deal of complexity is subsumed in this simple relation, however. Up to ‘income optimizing level’, the growth of population increases per capita income but beyond that it necessarily lowers the same. Population growth causes a disproportionate negative impact on the environment. Sulfur dioxide from the city paralyzes the cleaning mechanisms of the lungs, thus increasing the residence time of potential carcinogens in the agricultural chemicals. With this alone comes a massive risk of a higher number of people living on either bad nutrition habits or dying from hunger. Thus, in spite of planning, India has failed to achieve a satisfactory growth rate. But population increased at the rate of 2.2%. If we keep on doing that, it will slam down hard on biodiversity of Earth, as many species will disappear, because we left them without a home. Increase in population affects the economic, environmental and social development of the world. Far deadlier viruses, which easily could be scourges without precedent in the population at large, have on more than one occasion been confined to research workers largely by good luck [for example, the Marburg virus incident of 1967 (22) and the Lassa fever incident of 1970 (21, 23)]. Their income, as a consequence, is reduced and their capacity to save is diminished which, in turn, adversely affects capital formation. The “simplest assumption” is not valid, however, and this is the second flaw in Coale’s example (and in his thesis). Investigation of synergistic effects is one of the most neglected areas of environmental evaluation. In so arguing, he appears to make two unfounded assumptions. Whatever attempts may be made to solve distribution-related problems, they will be undermined if population growth continues, for two reasons. A certain preoccupation with density as a useful measure of overpopulation is apparent in the article by Coale (1). Man’s contemporary arsenal of synthetic technological bludgeons indisputably magnifies the potential for disaster, but these were evolved in some measure to cope with population pressures, not independently of them. Some negative effects of population growth are insecurity, crime, unemployment, underdevelopment, inequitable sharing of resources, and increased pollution of the environment. One of the factors responsible for environment degradation is population growth or population density. Moreover, many aspects of our technological fixes, such as synthetic organic pesticides and inorganic nitrogen fertilizers, have created vast environmental problems which seem certain to erode global productivity and ecosystem stability (26). As per latest data, population is already crossed 7.6 billion in the world. The Asian influenza epidemic of 1968 killed relatively few people only because the virus happened to be nonfatal to people in otherwise good health, not because of public health measures. Thus potentially attractive theoretical approaches—such as desalting seawater for agriculture, new irrigation systems, high-protein diet supplements—prove inadequate in practice. All these activities increase our per capita use of energy and our per capita impact on the environment. Population of the World is increasing day by day and it is becoming a huge concern for the world. The latter also increases per capita energy use, since the amount of energy invested per unit yield increases as less desirable land is cultivated. They are apathetic or even hostile toward efforts to avert further environmental and sociological deterioration, because they have no reason. Population growth is a factor that affects our ecosystem, in the broadest sense of this term. The stress on our environment is massive, and has been increasing as the population on Earth has grown larger. However, this is not a problem that we seek to answer in the future, as the issues we mention here are, if not already present, then undoubtedly imminent. Below a certain level of pollution trees will survive in smog. The countries suffering with heavy population explosion consider it as a threat to their economy and well-being. The hazard posed by the prevalence of these conditions in the world today is compounded by man’s unprecedented mobility: potential carriers of diseases of every description move routinely and in substantial numbers from continent to continent in a matter of hours. Currently, the Earth’s population is growing by 60,000 people every eight hours -- that’s two children born every second somewhere around the globe. In terms of the problem of feeding the world, for example, technological fixes suffer from limitations in scale, lead time, and cost (24). Therefore this paper will discuss these two theories for population growth and their effect on the resources and environment of the earth. Unless we can find another Earth where we can move half of our 7 billion population, it’s very obvious that we are using up our finite supply of resources. Precisely because population is the most difficult and slowest to yield among the components of environmental deterioration, we must start on it at once. This is a great way to contribute to the problems of uncontrolled population growth. As per latest data, population is already crossed 7.6 billion in the world. Source: MPHOnline.org As one example, consider the oversimplified but instructive situation in which each person in the population has links with every other person—roads, telephone lines, and so forth. As one example of diminishing returns, consider the problem of providing nonrenewable resources such as minerals and fossil fuels to a growing population, even at fixed levels of per capita consumption, As the richest supplies of these resources and those nearest to centers of use are consumed, we are obliged to use lower-grade ores, drill deeper, and extend our supply networks. For most technologies, the United States is already more than populous enough to achieve such economies and is doing so. The effects of overpopulation are quite severe. The 4 percent figure now amounts to about $30 billion per year. Also, when it comes to socio-economic factors, the more the population grows, there is always the chance that there will be fewer opportunities to get a job and how that will reflect on the possible rise of inflation and the increase of government debts. In this context, population control is obviously not a panacea—it is necessary but not alone sufficient to see us through the crisis. 1. Once a stock is depleted it may not recover—it may be nonrenewable. This is a blog in the MAHB ‘Let’s Talk About Population’ Blog Series. It cannot be stated too forcefully that the developed countries (or, more accurately, the overdeveloped countries) are the principal culprits in the consumption and dispersion of the world’s nonrenewable resources (12) as well as in appropriating much more than their share of the world’s protein. Complacency concerning this component of man’s predicament is unjustified and counterproductive. Questions should be directed to firstname.lastname@example.org. Here economies of scale do not apply at all, and diminishing returns are the rule. And our distaste for lung diseases apparently induced by sulfur dioxide inclines us to accept the hazards of radioactive waste disposal, fuel reprocessing, routine low-level emissions of radiation, and an apparently small but finite risk of catastrophic accidents associated with nuclear fission power plants. This problem, in turn, is illustrative of the situation in regard to many other resources, where similarly rapacious and shortsighted behavior by the developed nations is compromising the aspirations of the bulk of humanity to a decent existence. Population growth increases food demand and therefore the demand for agricultural land. Such savings, if available at all, would apply in the case of our sewage example to a change in the amount of effluent to be handled at an installation of a given type. Indeed, population control, the redirection of technology, the transition from open to closed resource cycles, the equitable distribution of opportunity and the ingredients of prosperity must all be accomplished if there is to be a future worth having. We are not suggesting here that electric cars, or nuclear power plants, or substitutes for phosphates are inherently bad. All too many people think in terms of national parks and trout streams when they say “environment.” For this reason many of the suppressed people of our nation consider ecology to be just one more “racist shuck” (18). Birth control and family planning is the first step that needs to be taken to ensure a gradual decline in the growth rate of the population. The correction of ghetto conditions in Detroit is neither more nor less important than saving the Great Lakes—both are imperative. Increase in population affects the economic, environmental and social development of the world. Like many of the difficulties we face, these problems will not be cured simply by stopping population growth; direct and well-conceived assaults on the problems themselves will also be required. From a very common-sense standpoint, the world we have is fixed in its size, and the Earth is not getting bigger. However, interestingly there are also few european countries that are worried about the decline in their population. One of the factors responsible for environment degradation is population growth or population density. First, a closer examination of very rapid increases in many kinds of consumption shows that these changes reflect a shift among alternatives within a larger (and much more slowly growing) category. We will not deal in detail with the best example of the global nature and interconnections of population resource and environmental problems—namely, the problems involved in feeding a world in which 10 to 20 million people starve to death annually (9), and in which the population is growing by some 70 million people per year. It produces energy equivalent to some 20 million metric tons of coal and consumes the equivalent of over 47 million metric tons (14). We call this notion “the Netherlands fallacy.” The Netherlands actually requires large chunks of the earth’s resources and vast areas of land not within its borders to maintain itself. China’s a little better, but still skewed in the wrong direction with 20 percent of the world's population that is responsible for 33 percent of its greenhouse emissions. What are ethical, viable strategies to decrease population? Thus the 760 percent increase in electricity consumption from 1940 to 1969 (4) occurred in large part because the electrical component of the energy budget was (and is) increasing much faster than the budget itself. It has been discovered that no matter how well conceived public efforts might be to restore and maintain Nigeria cities and communities as good places in which to live and find work, the ultimate outcome of city growth and its pattern of development … The former requires disproportionate energy use in obtaining and distributing water, fertilizer, and pesticides. Population growth, on the other hand, forces us into quantitative and qualitative changes in how we handle each unit volume of effluent—what fraction and what kinds of material we remove. It’s going to take some time before our efforts to correct our mistakes will have an effect. They are accounted for in our example by citing figures for the largest treatment plants of each type. It is to be emphasized that the possible existence of “economies of scale” does not invalidate these arguments. When those happen, the plants we use, or the animals that live in the forests are all in danger. Recent laboratory studies on human beings support the anecdotal evidence that crowding may increase aggressiveness in human males (20). 1. The need for food, space and raw materials has resulted in destruction of habitats and pollution. Here the loss of free-flowing rivers and other economic, esthetic, and ecological costs of massive water-movement projects represent increased per capita diseconomies directly stimulated by population growth. To ignore population today because the problem is a tough one is to commit ourselves to even gloomier prospects 20 years hence, when most of the “easy” means to reduce per capita impact on the environment will have been exhausted. You can view samples of our professional work here. They are too little, too late, and too expensive, or they have sociological costs which hobble their effectiveness (25). In many cases, the remedy for such deficiencies—for example, the provision of water and power to the wastelands of central Nevada—would be extraordinarily expensive in dollars, energy, and resources and would probably create environmental havoc. Although large parts of the land on Earth are still uninhabited and ''unused'', there is a reason for it - the conditions do not meet up to (human) standards. Moving people to more “habitable” areas, such as the central valley of California or, indeed, most suburbs, exacerbates another serious problem— the paving-over of prime farmland. Historically, human population control has been implemented with the goal of limiting the rate of population growth. Deforestation can happen on an even larger scale, and then we talk about desertification. For example, F increases with per capita consumption if technology is held constant, but may decrease in some cases if more benign technologies are introduced in the provision of a constant level of consumption. Population control refers to the practice of artificially altering the rate of growth of a human population. But overpopulation is seldom discussed as a public health issue. II. Similar considerations reveal the imprudence of citing, say, aluminum consumption to show that population growth is an “unimportant” factor in resource use. Consider municipal sewage, for example. Population density is a poor measure of population pressure, and redistributing population would be a dangerous pseudosolution to the population problem. Indeed, the Food and Agriculture Organization of the United Nations has reported that in 1969 the world suffered its first absolute decline in fisheries yield since 1950. Moreover, it is worth noting that, of the four environmental threats viewed by the prestigious Williamstown study (15) as globally significant, three are associated with pre-1940 technologies which have simply increased in scale [heavy metals, oil in the seas, and carbon dioxide and particulates in the atmosphere, the latter probably due in considerable part to agriculture (30)]. More than half of the worlds population is living in cities and this is increasing at rate of 1.5 percent. As a final example of the need to view “environment” broadly, note that human beings live in an epidemiological environment which deteriorates with crowding and malnutrition—both of which increase with population growth. All maps, graphics, flags, photos and original descriptions © 2020 worldatlas.com, Countries With the Highest Population Growth, Biggest Asteroid Impacts In Earth's History. Developing nations like India and some African countries tend to consume much less energy but add to the population crisis. Population growth is a factor that affects our ecosystem, in the broadest sense of this term. It is not only the question of available resources and its consumption, but it is also a concern about providing a quality life to the current and future generations. 1st Jan 1970 Environmental Sciences Reference this Disclaimer: This work has been submitted by a university student. Copyright © 2020 Millennium Alliance for Humanity and Biosphere. Similarly, as the richest fisheries stocks are depleted, the yield per unit effort drops, and more and more energy per capita is required to maintain the supply (5). Even if we manage to produce more food and resources people use and consume throughout their life, we will need to make more changes to the environment, which is already profoundly disturbed by the methods we use to find and spend materials we need for production. The relationship between population growth and economic development has been a recurrent theme in economic analysis since at least 1798 when Thomas Malthus famously argued that population growth would depress living standards in the long run. Factors affecting population growth The population growth is determined mainly by birth rate, death rate, and migration patterns (immigration and emigration). This is already so serious in California that, if current trends continue, about 50 percent of the best acreage in the nation’s leading agricultural state will be destroyed by the year 2020 (16). In Main Results: Population Growth and the SCC, we use a range of recent population projections, together with the DICE model, to show that population growth has a large effect on climate policy and the SCC. Actually, since the carrying capacity of the Australian continent is far below that of the United States, one would expect distribution problems—of which Sydney’s smog is one symptom—to be encountered at a much lower total population there. In an agricultural or technological society, each human individual has a negative impact on his environment. In addition, of course, many of the most serious environmental problems are essentially independent of the way in which population is distributed. Both of which we are running out of. Consider, for example, the recent article by Coale (1), in which he disparages the role of U.S. population growth in environmental problems by noting that since 1940 “population has increased by 50 percent, but per capita use of electricity has been multiplied several times.” This argument contains both the fallacies to which we have just referred. The population increased from 3 billion to 7 billion in a fairly short time, and this fact had immense effects on the world we live in. Second, population growth puts a disproportionate drain on the very financial resources needed to ’combat its symptoms. Again, under the simplest assumption, population growth accounts for 45 percent of the increase. Technologies, income and resource levels are held at year 2000 values. to believe they will share the fruits of success (19). Overpopulation is the existence of more people than the available … The second assumption is that the advent of the new technologies was independent of the attempt to meet human needs and desires in a growing population. Effects of Population Growth on our Environment! To review the sources, please download the article here. This is not an example of the work produced by our Essay Writing Service. The way we think about the complex system that exists on planet Earth, where everything is connected and seeks harmony, needs to be changed. In relation to theorem 2 we must emphasize that, even if population growth were halted, the present population of the world could easily destroy civilization as we know it. PDF | On Mar 20, 2016, Bhanu Phani Krishna and others published Effect of Population Growth on Economic Development in India | Find, read and cite all the research you need on ResearchGate Historically, this has been made possible by limiting the birth rate, usually by government mandate. Examples include corrections when the rapid growth may actually supply a population that wouldn't have existed to contribute otherwise. There is a wide choice of weapons—from unstable plant monocultures and agricultural hazes to DDT, mercury, and thermonuclear bombs. The global population has grown from 1 billion in 1800 to 7.8 billion in 2020. These links involve energy and materials in their construction and use. If there are more people, more fossil fuels will be burned into the atmosphere, which will then spiral back down on Earth, causing more pollution with the acid type of rains.
