The aim of this paper is to examine how increased world population through human beings change of life degrades the environment. Modernization of agriculture also threatens potentially valuable local crops. One of the ways that rivers, lakes and seas, get polluted is when sulfur oxides combine with moisture to form acid rain then these flows into the water sources.

The deterioration of environment can be a huge setback for tourism industry that rely on tourists for their daily livelihood. The sharp increase in worlds population demands that more land should be brought under Agricultural use or use intensified farming methods to increase food production this in turn causes harm to the environment either directly or indirectly.

Plants and creatures are evident parts of the environment, but it also includes the things on which they depend on, for example, streams, lakes, and soils. Globalization of population movements is needed like movement of capital and free trade in goods and services through WTO, for people to live and work wherever they like.

In India, life expectancy of males and females was only Pesticides can get into water via drift during pesticide spraying, by runoff from treated area, leaching through the soil.

A breakdown by region is as follows: Loss for Tourism Industry: Agriculture has changed dramatically, especially since the end of World War II.

The era of Agricultural revolution cleared fast lands to pave way for the green revolution. Where smog is produced abundantly, air quality deteriorates especially during hot weather, and it is during this period that asthma cases rise. Therefore, Global Footprint Network and its partner organizations have engaged with national governments and international agencies to test the results — reviews have been produced by France, Germany, the European Commission, Switzerland, Luxembourg, Japan and the United Arab Emirates.

In there were 83 cities with populations exceeding one million; but by this had risen to agglomerations of more than one million. Nations with high population growth are often not able to produce enough goods to meet their basic needs of their inhabitants. Until the s, seven out of ten children died before reaching reproductive age.

Environmental degradation

The country can achieve more sustainable land use if it combines planning and development with environmental management. Population can be defined in terms of a particular section, group, or type of people or animals living in an area or country.

In the medium variant, global fertility is projected to decline further to 2. Even many of the renewable resources like forests, grasslands etc.

Human overpopulation

Among the least developed countries, where life expectancy today is just under 50 years, it is expected to increase to 66 years by — It is the percentage of infants died out of those born in a year. Most of the centers in these regions do not have drains or even services to collect the garbage.

Population Growth: Causes, Characteristics and Explosion of Population Growth

Most the industries use environmentally unfriendly sources of energy like fossil fuels, coal, wood fuel and others that releases high levels of Oxides to the environment.

Air pollution pollutes the air that we breathe which causes health issues.

Demographic transition and Sub-replacement fertility The theory of demographic transition held that, after the standard of living and life expectancy increase, family sizes and birth rates decline.

Most of the other effects mentioned below are either consequent to the human population expansion or related to it. The environment and key natural resources in most African countries have been increasingly threatened by escalating and unsustainable pressures from fast-growing populations UNEP, The next 50 years will likely be the last period of rapid agricultural expansionbut the larger and wealthier population over this time will demand more agriculture.Fig 1 Human population growth till (2) Population policies which gears to reduce future growth represent logical responses to the environmental implications of population size (Stern et all ) although fertility diminution cannot be seen as sufficient response to contemporary human induced environmental change/5(19).

Population growth, though a source of development is commonly regarded as one of the most dreadful cause of environmental degradation. Population can be defined in terms of a particular section, group, or type of people or animals living in an area or country.

The human population on Earth is expanding rapidly which goes hand in hand with the degradation of the environment at large measures.

Humanity's appetite for needs is disarranging the environment's natural equilibrium. Production industries are venting smoke and discharging chemicals that are polluting water resources. Human population growth, refugees & environmental degradation 7 07 The global human population is now over billion, and.

Regardless of criticisms against the theory that population is a function of food availability, the human population is, on the global scale, undeniably increasing, as is the net quantity of human food produced — a pattern that has been true for roughly 10, years, since the human development of agriculture.

The linkages between human activity and environmental degradation are myriad but at the risk of some over-simplification one can usefully group the contributing factors in three categories: human population size, the per-capita rate of.
