A discussion on the fast population growth and global environment transformation

Urbanization and its implications for food and farming

Here we review the most prominent theories in the field of population and environment. Globally, in almost every country, humans are also becoming more urbanised. An average middle-class American consumes 3.

However, they have fewer of them.

Population and Environment

Globally, agricultural production has managed to meet the demands from a rapid growth in the proportion of the workforce not producing food and rapid changes in food demands towards more energy- and greenhouse gas emission-intensive food. This is an understandable fear, and a quick look at the circumstantial evidence certainly shows that as our population has increased, the health of our environment has decreased.

Clearly, efforts to understand the relationship between demographic and environmental change are part of a venerable tradition. In the case of CO2 emissions and footprints, the per capita impacts of high-income countries are currently 6 to 10 times higher than those in low-income countries.

Nonflammable, nonexplosive, noncorrosive, and nontoxic, the various forms of Freon gas seemed the perfect technical solution to a host of environmental and safety problems.

Students will examine threats to global security, such as international trade in weapons e. Although often depicted as being in opposition to Malthusianism, Malthus himself acknowledged that agricultural output increases with increasing population density just not fast enoughand Boserup acknowledged that there are situations under which intensification might not take place They will also examine the extent to which these efforts were successful.

Abstract The interactions between human population dynamics and the environment have often been viewed mechanistically. The IPAT equation is not perfect, but it does help to demonstrate that population is not the only or necessarily the most important factor relating to environmental damage.

A number of theories—often subscribed to by demographers—state that population is one of a number of variables that affect the environment and that rapid population growth simply exacerbates other conditions such as bad governance, civil conflict, wars, polluting technologies, or distortionary policies.

Freon soon came to dominate the market for refrigeration and opened up new retail markets because of its diminished capital requirements. To put this in perspective, if the rest of world lived like we do in Australia, we would need the equivalent of 3. Population pressures, industrialization, and urbanization have increased demands for limited natural resources and food resources, often straining the environment.

Globalization and the Changing Environment

Air conditioning had been used in specialized industrial applications ever since Willis H. By the first quarter of the twentieth century, the delivery of perishable foods throughout the United States—and international food shipments as well—had come to depend on mechanical refrigeration.

Toxicity and the need for large expensive compressors kept mechanical refrigeration from making headway with retail customers, who represented an immense potential demand.

We humans have spread across every continent and created huge changes to landscapes, ecosystems, atmosphere—everything. Globally, fertility is assumed to decline to 2. Chlorine compounds derived mostly from chlorinated fluorocarbon gases CFCsmass-produced by industrial societies for a variety of purposes, reacted in the stratospheric clouds over Antarctica during the cold, dark, winter months to produce forms of chlorine that rapidly deplete stratospheric ozone when the first rays of the Antarctic spring sunlight arrive Solomon, We need to step back and re-examine what is important and actively find ways to reduce the amount of resources we consume.

If so, might other groups challenge that inequality, including through the use of violence. They will also examine the extent to which these efforts were successful.

Political ecology also frequently informs the population-environment literature National Academy of Sciences published The Growth of World Population 7a report that reflected scientific concern about the consequences of global population growth, which was then reaching its peak annual rate of two percent.

For example, since conditions in the Middle East have seen population transfer also known as unplanned migration result in several million refugees fleeing countries including Syria, Iraq and Afghanistan.

Opponents question whether accepting these incentives is really is a choice, or whether the recipient has been coerced into it through community pressure or financial desperation.

The population has doubled over the last 25 years, to about 40 million people, and rapid population growth is set to continue. The conventional definition for urbanization used in this paper entails a shift in settlement patterns from dispersed to more dense settlement.

Thus for the high population to be relevant,the population is supposed to be having the purchasing power to buy the good and elleandrblog.com the purchasing power is visible then the population can form a good market for the goods and services which will encourage investment hence job.

A crisp dichotomy between the global North and the global South is becoming outmoded by the growth of a global consumer class, which has increased by hundreds of millions of people in the past two decades and will grow by billions in the decades ahead (56, 57).
