Human Population Growth And Its Effect Environmental Sciences Essay. These negative effects lead to subsequent problems such as clashes and fighting for dwindling resources, poor sanitation, and drug abuse. Generation of Waste: Due to his destructive activities, man […] Some of these are viral. Population growth causes a disproportionate negative impact on the environment. Historically, this has been made possible by limiting the birth rate, usually by government mandate. We are not suggesting here that electric cars, or nuclear power plants, or substitutes for phosphates are inherently bad. 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). The world is growing at an amazing rate. 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. The most important way to combat a steady rise in the population is education and empowerment. This proves only that their economists are as shortsighted as ours. What are ethical, viable strategies to decrease population? A lot of the species are already gone because of all the negative side-effects that come from population increase that inevitably increases resource demand. 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. The 4 percent figure now amounts to about $30 billion per year. One of the factors responsible for environment degradation is population growth or population density. 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. Up to ‘income optimizing level’, the growth of population increases per capita income but beyond that it necessarily lowers the same. Increase in population affects the economic, environmental and social development of the world. The “simplest assumption” is not valid, however, and this is the second flaw in Coale’s example (and in his thesis). Both of which we are running out of. Download as PDF. 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. Besides, students are not supposed to get creative here Read more>> 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. Human population growth is a concern for the whole world as it has a toll on the environment.. The global population has grown from 1 billion in 1800 to 7.8 billion in 2020. This is a great way to contribute to the problems of uncontrolled population growth. 1. Population growth is a factor that affects our ecosystem, in the broadest sense of this term. But overpopulation is seldom discussed as a public health issue. Consider municipal sewage, for example. In this wealth of material, several questionable assertions have been appearing with increasing frequency. It’s going to take some time before our efforts to correct our mistakes will have an effect. Investigation of synergistic effects is one of the most neglected areas of environmental evaluation. 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. Moreover, it is often assumed that population size and per capita impact are independent variables, when in fact they are not. 1126 Words 5 Pages. Demand for forest products from non-agricultural sectors (industries, mining etc., including through export channels). 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. 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. 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. In addition, of course, many of the most serious environmental problems are essentially independent of the way in which population is distributed. The former requires disproportionate energy use in obtaining and distributing water, fertilizer, and pesticides. Theorem 5 states that theoretical solutions to our problems are often not operational, and sometimes are not solutions. 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 … As per latest data, population is already crossed 7.6 billion in the world. Due to uncontrolled human spending of the resources, some areas on Earth turn into deserts. Problems of population size and growth, resource utilization and depletion, and environmental deterioration must be considered jointly and on a global basis. 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. Thus, in spite of plan­ning, India has failed to achieve a satisfactory growth rate. Other factors may cause much steeper positive slopes in the per capita impact function, F(P). Thus potentially attractive theoretical approaches—such as desalting seawater for agriculture, new irrigation systems, high-protein diet supplements—prove inadequate in practice. 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. The same argument can be applied to the question of resources: how much can we actually produce, and how many people will starve? (Will we justify the rape of Canada’s rivers to “colonize” more of our western deserts?). 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. 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 this context, population control is obviously not a panacea—it is necessary but not alone sufficient to see us through the crisis. Technologies, income and resource levels are held at year 2000 values. As you can see, the impact of global population growth is far-reaching, as it affects everyone and everything on this planet. With sustained growth and rapid growth though there is a risk of overpopulation. Theorem 3 deals with a problem related to the inequitable utilization of world resources. Areas that are uninhabited or sparsely populated today are presumably that way because they are deficient in some of the requisite factors. As noted earlier, the services of capital and labor do not explain economic growth in its entirety. Essay on Population Growth and Its Effects – Essay 2 (300 Words) Introduction. More: Global Climate Change Facts Some negative effects of population growth are insecurity, crime, unemployment, underdevelopment, inequitable sharing of resources, and increased pollution of the environment. 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. 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. Just how many of us are there and how is our rising population affecting human health? 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). 1.1 Background to the Study. Questions should be directed to joan@mahbonline.org. In the last 50 years, the number of people on this planet has more than doubled. 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. Future population growth can only result to further degradation of our environment. 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. About 40% of worldwide pregnancies are … Pitfalls abound in the interpretation of manifest increases in the total impact I. The angles from which you can approach this problem are almost endless. It seems likely that part of this decline is attributable to pollution originating in terrestrial agriculture. The need for food, space and raw materials has resulted in destruction of habitats and pollution. One phenomenon is the threshold effect. The joint effect may be much more than the sum of the individual effects. 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. What will we do if we continue to grow at exponential rates? Rapid growth of population directly effects per capita income in an economy. Ageing populations are another element to the multi-faceted implications of demographic population change, and pose challenges of their own. In the period from the 1950s to the 1980s, concerns about global population growth and its effects on poverty, environmental degradation, and political stability led to efforts to reduce population growth rates. In particular, population density plays the most important role in shaping the socio-economic environment. 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. 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. (We shall see in connection with theorem 5 that there are limits to the improvements one should anticipate from such “technological fixes.’’). 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. Its effects are felt on the natural environment also. Questions should be directed to. 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. 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. 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. 2515 words (10 pages) Essay. 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. Failure in any of these areas will surely sabotage the entire enterprise. 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. Five hundred and five people may overload the system and result in a “polluted” or eutrophic lake. 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. Some observers argue that the poor countries are today economically dependent on our use of their resources, and indeed that economists in these countries complain that world demand for their raw materials is too low (1). To review the sources, please download the article here. More and more problems occur every year and their cause lies in the mankind itself. Factors affecting population growth The population growth is determined mainly by birth rate, death rate, and migration patterns (immigration and emigration). Copyright © 2020 Millennium Alliance for Humanity and Biosphere. to believe they will share the fruits of success (19). 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. 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. 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 Most of the environmental damage being seen in the last fifty-odd years is because of the growing number of pe… Effects of Population Growth on our Environment! Slums, cockroaches, and rats are ecological problems, too. Problems of population size and growth, resource utilization and depletion, and environmental deterioration must be considered jointly and on a global basis. What Are The Impacts Of Bottom Trawling On The Environment? Learn More About PopEd. Effect # 1. They are apathetic or even hostile toward efforts to avert further environmental and sociological deterioration, because they have no reason. But population increased at the rate of 2.2%. Here economies of scale do not apply at all, and diminishing returns are the rule. 2. 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 most essential resources, we and all the other species we depend on, are food and water. The ecological problems created by high-yield agriculture are awesome (3, 10) and are bound to have a negative feedback on food production. Due to rapid population growth, disease-carrying organisms can diffuse and spread faster in overpopulated areas. 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)]. The way we think about the complex system that exists on planet Earth, where everything is connected and seeks harmony, needs to be changed. 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!). is a venture of the Millennium Alliance for Humanity and the Biosphere. 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). Naturally, we do not dispute that smog and most other familiar urban ills are serious problems, or that they are related to population distribution. 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. Having a big population can lead to new viral diseases because the unhygienic practices of mankind will have ripple effects. Typically, attempts are made both to overproduce on land already farmed and to extend agriculture to marginal land. 1. Low per capita income For a balanced per capita income, the economic and population growth must go hand in hand. Not only is there a connection between population size and per capita damage to the environment, but the cost of maintaining environmental quality at a given level escalates disproportionately as population size increases.
