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. John Platt has aptly described man’s present predicament as “a storm of crisis problems” (31). This is not to say that important gains have not been made through the application of technology to agriculture in the poor countries, or that further technological advances are not worth seeking. Population of the World is increasing day by day and it is becoming a huge concern for the world. About 40% of worldwide pregnancies are … The effect of growing population will be an increased demand for resources and space. If there are too many people, even the most wisely managed technology will not keep the environment from being overstressed. Technologies, income and resource levels are held at year 2000 values. In this wealth of material, several questionable assertions have been appearing with increasing frequency. Having a big population can lead to new viral diseases because the unhygienic practices of mankind will have ripple effects. Population Control And Its Effect On The Growth Of A Human Population. 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. (Evidently, it cannot be emphasized enough that carrying capacity includes the availability of a wide variety of resources in addition to space itself, and that population pressure is measured relative to the carrying capacity. Actually, man’s record as a simplifier of ecosystems and plunderer of resources can be traced from his probable role in the extinction of many Pleistocene mammals (29), through the destruction of the soils of Mesopotamia by salination and erosion, to the deforestation of Europe in the Middle Ages and the American dustbowls of the 1930’s, to cite only some highlights. The angles from which you can approach this problem are almost endless. 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. If population size were reduced and per capita consumption remained the same (or increased), we would still quickly run out of vital, high-grade resources or generate conflicts over diminishing supplies. In terms of the problem of feeding the world, for example, technological fixes suffer from limitations in scale, lead time, and cost (24). Up to ‘income optimizing level’, the growth of population increases per capita income but beyond that it necessarily lowers the same. Population density is a poor measure of population pressure, and redistributing population would be a dangerous pseudosolution to the population problem. While the effects of population growth on per capita economic growth may be quite variable, productivity growth is unequivocally related to the “economic component” of growth that Piketty points to as the source of improvements in the standard of living. 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. The growth of the human population has impacted the planet and affected biodiversity. 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. Increase in population affects the economic, environmental and social development of the world. Essay on Population Growth and Its Effects – Essay 2 (300 Words) Introduction. Complacency concerning this component of man’s predicament is unjustified and counterproductive. It is time to admit that there are no monolithic solutions to the problems we face. 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. Our discussion centers around five theorems which we believe are demonstrably true and which provide a framework for realistic analysis: We now examine these theorems in some detail. The effects of population growth are varied and vast. Population Growth and Income Growth: During 1950-51 and 1999-00, India’s national in­come (at 1993-94 prices) increased by 4.4% per annum. Deforestation can happen on an even larger scale, and then we talk about desertification. A second source of the fisheries decline is, of course, overexploitation of fisheries by the developed countries. As you can see, the impact of global population growth is far-reaching, as it affects everyone and everything on this planet. Demand for forest products from non-agricultural sectors (industries, mining etc., including through export channels). 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. Similar considerations reveal the imprudence of citing, say, aluminum consumption to show that population growth is an “unimportant” factor in resource use. 1126 Words 5 Pages. Large fires every year, massive earthquakes, tsunamis, and hurricanes grow stronger each year. Copyright © 2020 Millennium Alliance for Humanity and Biosphere. Those who so argue often add that, anyway, population control would be the slowest to take effect of all possible attacks on our various problems, since the inertia in attitudes and in the age structure of the population is so considerable. They are too little, too late, and too expensive, or they have sociological costs which hobble their effectiveness (25). 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. In addition, population growth increases predominantly urban land areas (United Nations, 2004). 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. In populous, industrial nations such as the United States, most economies of scale are already being exploited; we are on the diminishing returns part of most of the important curves. 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. Population growth increases food demand and therefore the demand for agricultural land. Population growth is a factor that affects our ecosystem, in the broadest sense of this term. Examples include corrections when the rapid growth may actually supply a population that wouldn't have existed to contribute otherwise. 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. But it must be stressed that even the most enlightened technology cannot relieve the necessity of grappling forthrightly and promptly with population growth [as Norman Borlaug aptly observed on being notified of his Nobel Prize for development of the new wheats (27)]. Some of these are viral. 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. 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. The total energy use, a more important figure than its electrical component in terms of resources and the environment, increased much less dramatically—140 percent from 1940 to 1969. Not mentioned here are the effects of global warming, which will surely worsen due to the increased carbon footprint. Due to uncontrolled human spending of the resources, some areas on Earth turn into deserts. It also imports all of its cotton, 77 percent of its wool, and all of its iron ore, antimony, bauxite, chromium, copper, gold, lead, magnesite, manganese, mercury, molybdenum, nickel, silver, tin, tungsten, vanadium, zinc, phosphate rock (fertilizer), potash (fertilizer), asbestos, and diamonds. But, at some point, when a small increment in population produces a small increment in smog, living trees become dead trees. This dramatic example of diminishing returns in pollution control could be repeated for stack gases, automobile exhausts, and so forth. It produces energy equivalent to some 20 million metric tons of coal and consumes the equivalent of over 47 million metric tons (14). 1st Jan 1970 Environmental Sciences Reference this Disclaimer: This work has been submitted by a university student. The world population is growing at an alarming rate. The need for food, space and raw materials has resulted in destruction of habitats and pollution. While people are moving from place to place more and more, the world is undergoing the largest wave of urban growth in history. Encouraging that trend hardly seems wise. The desperate and repressive measures for population control which might be contemplated then are reason in themselves to proceed with foresight, alacrity, and compassion today. He is responsible for some of the simplification (and resulting destabilization) of ecological systems which results from the practice of agriculture (3). For instance, Wattenberg states that the United States is not very crowded by “international standards” because Holland has 18 times the population density (13). All these activities increase our per capita use of energy and our per capita impact on the environment. John P. Holdren, Paul R. Ehrlich | October 22, 2019 | Leave a Comment To conclude that this means population control should be assigned low priority strikes us as curious logic. 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. Due to rapid population growth, disease-carrying organisms can diffuse and spread faster in overpopulated areas. 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). Experts believe if we continue to grow at this pace, we’ll need … 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. The total negative impact of such a society on the environment can be expressed, in the simplest terms, by the relation, where P is the population, and F is a function which measures the per capita impact. Of course, diminishing returns and threshold effects may be still more serious: we may easily have an eightfold increase in control costs for a doubling of population. When a population of students grows rapidly, it can lead to teacher shortages, lack of funding and overcrowded schools. In particular, population density plays the most important role in shaping the socio-economic environment. For example, our first generation of smog-control devices increased emissions of oxides of nitrogen while reducing those of hydrocarbons and carbon monoxide. The impacts of a growing population need to be brought to the attention of all. 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. Therefore this paper will discuss these two theories for population growth and their effect on the resources and environment of the earth. (Electricity comprised 12 percent of the U.S. energy consumption in 1940 versus 22 percent today.) 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. Rapid growth of population directly effects per capita income in an economy. By Antonia Čirjak on May 3 2020 in World Facts. 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)]. II. Population growth is placing stress on the natural environment, creating scarcity, and leading to problems such as deforestation and global warming. Theorem 5 states that theoretical solutions to our problems are often not operational, and sometimes are not solutions. Perhaps the most serious of these is the notion that the size and growth rate of the U.S. population are only minor contributors to this country’s adverse impact on local and global environments (1, 2). Our previous equation is more accurately written. This is a blog in the MAHB ‘Let’s Talk About Population’ Blog Series. 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. The first of these is the depletion of resources. Government officials who focus on growth may find that they suffer the consequences of poor planning. 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. Once a stock is depleted it may not recover—it may be nonrenewable. 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. The world is growing at an amazing rate. 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). 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. Problems of population size and growth, resource utilization and depletion, and environmental deterioration must be considered jointly and on a global basis. Human population growth is a concern for the whole world as it has a toll on the environment.. This is a great way to contribute to the problems of uncontrolled population growth. Precisely because population is the most difficult and slowest to yield among the components of environmental deterioration, we must start on it at once. If we think about just a simple hypothesis, one that would be hard to argue against, it would say that the relationship between population growth and the quality of life on the planet is forever linked. Among the most definite and devastating effects of overpopulation i… One phenomenon is the threshold effect. Other factors may cause much steeper positive slopes in the per capita impact function, F(P). “Environment” must be broadly construed to include such things as the physical environment of urban ghettos, the human behavioral environment, and the epidemiological environment. Whatever attempts may be made to solve distribution-related problems, they will be undermined if population growth continues, for two reasons. Its effects are felt on the natural environment also. His argument would be more persuasive if problems of population distribution were the only ones with environmental consequences, and if population distribution were unrelated to resource distribution and population size. The residual per capita impact, after all the best choices have been made, must then be multiplied by the population engaging in the activity. One of the factors responsible for environment degradation is population growth or population density. Theorem 3 deals with a problem related to the inequitable utilization of world resources. 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. Population growth is the increase in the number of individuals in a population.Global human population growth amounts to around 83 million annually, or 1.1% 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. 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. This article was originally published in Science on March 26, 1971. This proves only that their economists are as shortsighted as ours. Conflict within the United States blocks progress toward solving our problems; conflict among nations can easily “solve” them once and for all. People live where they do not because of a perverse intention to add to the problems of their society but for reasons of economic necessity, convenience, and desire for agreeable surroundings. Contraception is when you intentionally want to stop pregnancy. 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 … Economist Joseph Spengler has estimated that 4 percent of national income goes to support our 1 percent per year rate of population growth in the United States (17). Questions should be directed to. 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. 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. Due to rapid population growth, disease-carrying organisms can diffuse and spread faster in overpopulated areas. Population growth causes a disproportionate negative impact on the environment. We must pay careful attention to sources of conflict both within the United States and between nations. This study explores the effects of population growth on economic development in Rwanda over the period of 1974–2013. Just how many of us are there and how is our rising population affecting human health? Diminishing returns are also operative in increasing food production to meet the needs of growing populations. One would expect water, soils, or the ability of the environment to absorb wastes to be the limiting resource in far more instances than land area.). 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. POPULATION GROWTH EFFECTS ON TRANSPORTATION FACILITIES IN WARRI METROPOLIS CHAPTER ONE. 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. Failure in any of these areas will surely sabotage the entire enterprise. Everything comes back together to bite back on the hand that has no control over what it does. Such arguments leave little ground for the assumption, popularized by Barry Commoner (2, 8) and others, that a 1 percent rate of population growth spawns only 1 percent effects. Increased diversity and human capital are among the positive effects of population growth. 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. This, in turn, … Developing nations like India and some African countries tend to consume much less energy but add to the population crisis. The Earth can only produce a limited amount of water and food, which is falling short of the current needs. We may be able to afford the technology to mine lower grade deposits when we have squandered the world’s rich ores, but the underdeveloped countries, as their needs grow and their means remain meager, will not be able to do so. Problems of population size and growth, resource utilization and depletion, and environmental deterioration must be considered jointly and on a global basis. Five hundred and five people may overload the system and result in a “polluted” or eutrophic lake. Population Education provides K-12 teachers with innovative, hands-on lesson plans and professional development to teach about human population growth and its effects on the environment and human well-being. Areas that are uninhabited or sparsely populated today are presumably that way because they are deficient in some of the requisite factors. The cost ranges from two to four times as much as for secondary treatment (17 cents per 1000 gallons for carbon absorption; 34 cents per 1000 gallons for disinfection to yield a potable supply). Low per capita income For a balanced per capita income, the economic and population growth must go hand in hand. The environment, culture, politics, food supply, and demand, the undermined ability of some of the natural resources to replenish - everything is affected by the growth of population. 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. Theoretical solutions to our problems are often not operational and sometimes are not solutions. It provides the reader with real and credible information about the current state of overpopulation, its tendencies and projections into the future. What will we do if we continue to grow at exponential rates? Pitfalls abound in the interpretation of manifest increases in the total impact I. This rapid urbanization coupled with population growth is changing the landscape of human settlement, posing significant risks on living conditions, the environment, and development. Recent laboratory studies on human beings support the anecdotal evidence that crowding may increase aggressiveness in human males (20). Racism, economic exploitation, and war will not be eliminated by population control (of course, they are unlikely to be eliminated without it). Similarly, electric automobiles would simply shift part of the environmental burden of personal transportation from the vicinity of highways to the vicinity of power plants. MAHB ‘Let’s Talk About Population’ Blog Series. The MAHB Blog is a venture of the Millennium Alliance for Humanity and the Biosphere. Essay on Population Growth and Its Effects – Essay 2 (300 Words) Introduction. Not only do such measures tend to be slow, costly, and insufficient in scale, but in addition they most often shift our impact rather than remove it. Effect # 1. Ageing populations are another element to the multi-faceted implications of demographic population change, and pose challenges of their own. displaying the fact that impact can increase faster than linearly with population. (Will we justify the rape of Canada’s rivers to “colonize” more of our western deserts?). He also participates in the utilization of renewable and nonrenewable resources. 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. 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. Acid rains are called acid because of the sulfur dioxide that first goes into the atmosphere, and then rains back down on Earth. These results underscore long-standing suspicions that population growth, translated through the inevitable uneven distribution into physical crowding, will tend to make the solution of all of our problems more difficult. The population growth enhances the limited natural resources use such as coal and petroleum, which degrades the environment in the form of air, soil, and water pollution. Its effects are felt on the natural environment also. Since rationally acting agents use the economically most suitable resource first, additional agricultural land is likely to be less profitable. A certain preoccupation with density as a useful measure of overpopulation is apparent in the article by Coale (1). The net result has been modest 2.1% in­crease in per capita income. We argue rather that they, too, pose environmental costs which must be weighed against those they eliminate. In a typical situation, this would yield doubled per capita costs, or quadrupled total costs (and probably energy consumption) in this sector for a doubling of population. 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 same argument can be applied to the question of resources: how much can we actually produce, and how many people will starve? For most technologies, the United States is already more than populous enough to achieve such economies and is doing so. Overpopulation is the existence of more people than the available … This is not an example of the work produced by our Essay Writing Service. Population growth is less important a factor here: income growth and the technological factor play a much greater role in this case than in the preceding one. These links involve energy and materials in their construction and use. However, interestingly there are also few european countries that are worried about the decline in their population. We propose to deal with this and several related misconceptions here, before persistent and unrebutted repetition entrenches them in the public mind—if not the scientific literature. Nor is there any reason to believe that modern medicine has made widespread plague impossible (21). We are not suggesting here that electric cars, or nuclear power plants, or substitutes for phosphates are inherently bad. 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. Similarly, the problems of resource depletion and ecosystem simplification by agriculture depend on how many people there are and their patterns of consumption, but not in any major way on how they are distributed. Population of the World is increasing day by day and it is becoming a huge concern for the world. Now consider a situation in which the limited capacity of the environment to absorb abuse requires that we hold man’s impact in some sector constant as population doubles. Population growth, even rapid population growth, can be a positive thing. Besides, students are not supposed to get creative here Read more>> Under the simplest assumption (that is, that a given increase in population size accounts for an exactly proportional increase in consumption), this would mean that 38 percent of the increase in energy use during this period is explained by population growth (the actual population increase from 1940 to 1969 was 53 percent). In the last 50 years, the number of people on this planet has more than doubled. This is referred to as overpopulation. More: Global Climate Change Facts Biodiversity and the quality of our own lives depend on it. Thus a fairer measure is combined consumption of aluminum and steel, which has risen only 117 percent since 1940. This effect occurs in part because costs increase very rapidly as one tries to reduce contaminants per unit volume of effluent to lower and lower levels (diminishing returns again!). Download as PDF. Questions should be directed to joan@mahbonline.org. 2515 words (10 pages) Essay. By current estimates, we will be a population of 10 billion by the year 2050. Who and what feels the impact of population growth? It is now becoming more widely comprehended that the United States alone accounts for perhaps 30 percent of the nonrenewable resources consumed in the world each year (for example, 37 percent of the energy, 25 percent of the steel, 28 percent of the tin, and 33 percent of the synthetic rubber) (11).
