population growth and its effects

Theoretical solutions to our problems are often not operational and sometimes are not solutions. The growth of the human population has impacted the planet and affected biodiversity. 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. Questions should be directed to [email protected] Population control refers to the practice of artificially altering the rate of growth of a human population. In many cases the choice is not obvious, and in all cases there will be some environmental impact. A Population Boom Could Lead To More Malignant Diseases. John P. Holdren, Paul R. Ehrlich | October 22, 2019 | Leave a Comment The net result has been modest 2.1% in­crease in per capita income. Resources, such as water, are in very short supply, and people cluster where resources are available. One of the commonest errors made by the uninitiated is to assume that population density (people per square mile) is the critical measure of overpopulation or underpopulation. 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). But overpopulation is seldom discussed as a public health issue. Population size influences per capita impact in ways other than diminishing returns. 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. 2515 words (10 pages) Essay. The correction of ghetto conditions in Detroit is neither more nor less important than saving the Great Lakes—both are imperative. For instance, Wattenberg states that the United States is not very crowded by “international standards” because Holland has 18 times the population density (13). Population growth, even rapid population growth, can be a positive thing. Both of which we are running out of. 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. However, interestingly there are also few european countries that are worried about the decline in their population. 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. By Antonia Čirjak on May 3 2020 in World Facts. 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 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. 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. Other factors may cause much steeper positive slopes in the per capita impact function, F(P). When a population of students grows rapidly, it can lead to teacher shortages, lack of funding and overcrowded schools. 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. Typically, attempts are made both to overproduce on land already farmed and to extend agriculture to marginal land. A Population Boom Could Lead To More Malignant Diseases Having a big population can lead to new viral diseases because the unhygienic practices of mankind will have ripple effects. The world is growing at an amazing rate. The effects of overpopulation are quite severe. The Earth can only produce a limited amount of water and food, which is falling short of the current needs. 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. Due to rapid population growth, disease-carrying organisms can diffuse and spread faster in overpopulated areas. II. In connection with the five theorems elaborated here, we have dealt at length with the notion that population growth in industrial nations such as the United States is a minor factor, safely ignored. This means per capita effectiveness of pollution control in this sector must double (that is, effluent per person must be halved). In particular, population density plays the most important role in shaping the socio-economic environment. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. 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. He is responsible for some of the simplification (and resulting destabilization) of ecological systems which results from the practice of agriculture (3). The theory was simple: given that there is a fixed quantity of land, population growth will eventually reduce the amount of resources that each individual can consume, ultimately … 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 population boom that has overwhelmed the system results from improvement in medical care at both ends of the life spectrum—according to World Bank data, infant mortality has fallen from 113 per 1,000 births in 1980 to 17.9 per 1,000 in 2012, and life expectancy has grown from 48 … 1. 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. In addition, of course, many of the most serious environmental problems are essentially independent of the way in which population is distributed. It is to be emphasized that the possible existence of “economies of scale” does not invalidate these arguments. Essay on Population Growth and Its Effects – Essay 2 (300 Words) Introduction. These negative effects lead to subsequent problems such as clashes and fighting for dwindling resources, poor sanitation, and drug abuse. It seems likely that part of this decline is attributable to pollution originating in terrestrial agriculture. 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. 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. Source: MPHOnline.org We argue rather that they, too, pose environmental costs which must be weighed against those they eliminate. 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 About 40% of worldwide pregnancies are … 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. In short, he has failed to recognize that per capita consumption of energy and resources, and the associated per capita impact on the environment, are themselves functions of the population size. As per latest data, population is already crossed 7.6 billion in the world. Problems of population size and growth, resource utilization and depletion, and environmental deterioration must be considered jointly and on a global basis. Population growth is a factor that affects our ecosystem, in the broadest sense of this term. The consequences of such an event are severe and major. 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 countries, where population growth rate exceeds economic growth, the per capita income lowers. Such measures may occasionally include the redistribution of population, but the considerable difficulties and costs of this approach should not be underestimated. Whatever attempts may be made to solve distribution-related problems, they will be undermined if population growth continues, for two reasons. Those same forests are already undergoing extreme deforestation, but the stress would be even higher if we would need more wood for all the different products it is used in. Of course, whether F (P) is an increasing or decreasing function of P depends in part on whether diminishing returns or economies of scale are dominant in the activities of importance. Its effects are felt on the natural environment also. 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 way we think about the complex system that exists on planet Earth, where everything is connected and seeks harmony, needs to be changed. 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. In terms of the problem of feeding the world, for example, technological fixes suffer from limitations in scale, lead time, and cost (24). The interlocking crises in population, resources, and environment have been the focus of countless papers, dozens of prestigious symposia, and a growing avalanche of books. 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. Moreover, it is often assumed that population size and per capita impact are independent variables, when in fact they are not. 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. INTRODUCTION. Second, population growth puts a disproportionate drain on the very financial resources needed to ’combat its symptoms. 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). 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. Most of the environmental damage being seen in the last fifty-odd years is because of the growing number of pe… 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. The first of these is the depletion of resources. The third individual partial impact relates to the effect of population growth on food demand. The most essential resources, we and all the other species we depend on, are food and water. 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. To review the sources, please download the article here. It seems safe to conclude that the faster we grow the less likely it is that we will find the funds either to alter population distribution patterns or to deal more comprehensively and realistically with our problems. Because of this consumption, and because of the enormous negative impact on the global environment accompanying it, the population growth in these countries must be regarded as the most serious in the world today. Pitfalls abound in the interpretation of manifest increases in the total impact I. The cost of removing 80 to 90 percent of the biochemical and chemical oxygen demand, 90 percent of the suspended solids, and 60 percent of the resistant organic material by means of secondary treatment is about 8 cents per 1000 gallons (3785 liters) in a large plant (7). 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. 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. The residual per capita impact, after all the best choices have been made, must then be multiplied by the population engaging in the activity. This study explores the effects of population growth on economic development in Rwanda over the period of 1974–2013. 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)].
