Rapid population growth in a country like India is threatening the environment through expansion and intensification of agriculture, uncontrolled growth of urbanization and industrialization, and destruction of natural habitats.

The effect of population growth on environmental quality

The current population of the Earth is almost 7. While a lot of positive steps are being taken to better ensure the sustainability of humans on our planet, the problem of having too many people has made lasting solutions more challenging to find. The term overpopulation is used to describe a situation in which the world or area has a population so large that the people there are suffering as a result. In other words, the population exceeds the region or planet's carrying capacity--the number of people, other living organisms, or crops that can be supported without environmental degradation. Their suffering may include a shortage of food, limited access to healthcare and other public services, overcrowding, and high unemployment.

The value placed upon large families especially among under-privileged rural populations in less developed countries who benefit least from the process of development , the assurance of security for the elderly, the ability of women to control reproduction, and the status and rights of women within families and within societies are significant cultural factors affecting family size and the demand for family planning services. Even with a demand for family planning services, the adequate availability of and access to family planning and other reproductive health services are essential in facilitating slowing of the population growth rate. Also, access to education and the ability of women to determine their own economic security influence their reproductive decisions.

Population Growth and Environmental Degradation : The Case of Bangladesh

One of the most compelling reasons for studying environmental science and management is the fact that, in the view of many leading authorities, we are now experiencing an environmental crisis; indeed, many authors have claimed that the present environmental crisis is unprecedented in its magnitude, pace and severity Park Awareness of this environmental crisis has grown since the s, partly as a result of the prominence given to major so-called 'environmental' disasters such as the Sahelian droughts of the s and s and the nuclear accident at Chernobyl in Consequently, a wide range of environmental problems has emerged; those problems include anthropogenic climate change 'global warming' , the depletion of stratospheric ozone the 'ozone hole' , the acidification of surface waters 'acid rain' , the destruction of tropical forests, the depletion and extinction of species, and the precipitous decline of biodiversity. Yet, while all of these problems have physical environmental manifestations, their causes - and their potential solutions - are invariably bound up with human attitudes, beliefs, values, needs, desires, expectations, and behaviours. Thus the symptoms of the environmental crisis cannot be regarded purely as physical problems requiring solutions by environmental 'specialists'; instead, they are intrinsically human problems and they are intimately related to the question of what it means to be human. At this point, a very brief overview of the environmental crisis may be helpful. It is important to emphasise that a wide range of views about the nature and severity of the current environmental crisis exists, and some of the issues are highly controversial.

This paper summarizes research on the effect of population growth on environmental quality. Land transformations induced by the spatial expansion of agriculture are probably the major route by which population growth has affected features of the natural environment. These transformations are not automatic and their extent is influenced by social institutions. Intensification of agricultural land use is an alternative response with its own set of environmental implications. These are especially salient in the case of expanded irrigation. Nevertheless, population policy may play a useful role in strategies to reduce industrial pollution.

While the causes are complex, one significant contributor to the problem is population growth. Understanding the relationship between population growth and environmental issues may be the first step toward identifying real solutions. Population growth is the increase in the number of people living in a particular area. Since populations can grow exponentially, resource depletion can occur rapidly, leading to specific environmental concerns such as global warming, deforestation and decreasing biodiversity. Populations in developed countries trend toward using substantially more resources, while populations in developing countries feel the impacts of environmental problems more quickly. The concept of population growth is tricky because populations can grow exponentially — similar to the way a bank or credit card company compounds interest. If you plot this equation, you see a curve arching upward over time as the population increases exponentially, assuming no change in the rate.


The ecological consequences were soil erosion, degradation of vegetation, and water supply contamination and decline. Eventually, famines will occur and lead to.


What Are Environmental Problems Due to Population Growth?

This paper examines possible relationships between demographic processes and the environment in rural areas in developing countries. Evidence is reviewed on increasing degradation in the forms of deforestation of highland forests as well as lowland forests , soil erosion and soil desiccation. The conceptual framework considers changes in demographics as well as economic behaviour being induced by population growth and increasing pressures upon the land, but the focus here is on economic changes in the form of land extensification—often involving internal migration—and land intenstification. Despite data problems, the expected relationships are observed: countries with higher rural population growth tend to have larger increases in the arable land area and associated deforestation, but the intensification effects appear stronger.

There are many environmental issues in India. Air pollution , water pollution , garbage domestically prohibited goods and pollution of the natural environment are all challenges for India. Nature is also causing some drastic effects on India. The situation was worse between through

Unit 1 The Earth System and its Components

Это культовая фигура, икона в мире хакеров. Если Танкадо говорит, что алгоритм не поддается взлому, значит, так оно и. - Но ведь для обычных пользователей они все не поддаются взлому. - Верно… - Стратмор задумался.

Они сказали - агентство. АНБ. - Никогда о таком не слышал. Беккер заглянул в справочник Управления общей бухгалтерской отчетности США, но не нашел в нем ничего похожего. Заинтригованный, он позвонил одному из своих партнеров по теннису, бывшему политологу, перешедшему на службу в Библиотеку конгресса. Слова приятеля его очень удивили. Дело в том, что АНБ не только существовало, но и считалось одной из самых влиятельных правительственных организаций в США и во всем мире.

 Уверен, ты догадаешься сама, - сказал Стратмор.  - Он не очень любит Агентство национальной безопасности. - Какая редкость! - саркастически парировала Сьюзан. - Он участвовал в разработке ТРАНСТЕКСТА. Он нарушил правила.

 Пока. Есть вести от Дэвида. Стратмор покачал головой. - Я попросил его не звонить мне, пока он не найдет кольцо. - Почему? - удивилась Сьюзан.
