WPO Home Search Join our ListServ Contact Us Population Attitudes About World Population Growth An overwhelming majority correctly perceives the world's population as growing and believes that world population growth is a significant problem. However, this majority is divided as to how pressing this problem is-both as a general matter and in terms of security and environmental concerns. In a September 1998 Belden and Russonello poll, 83% described population as growing while only 16% said it was stable (13%) or shrinking (3%). (Only 1% said they did not know-unusually low for a poll question that quizzes respondents on their knowledge. These responses were almost exactly the same to the same question in a 1994 poll.) [ ] The median estimate of world population was fairly accurate, but the median estimate of the rate of population growth was exaggerated. [ An overwhelming majority views overpopulation as a significant problem, but this majority is divided as to how pressing this problem is. This pattern came up in several polls. In June 2002, the Chicago Council on Foreign Relations found only 12% who thought "world population growth" was "not an important threat at all" "to the vital interest of the US in the next ten years." An overwhelming 86% saw it as a threat, but were divided between 44% who thought it "critical" and 42% who thought it "important but not critical." [ ]Similarly, 88% said in an October 1999 Gallup poll that "population growth internationally" was or would be a problem, while only 11% said they "don't expect it to become a problem." However the 88% was divided between those who said it was "a major problem now" (47%) and those who characterized it as "not a problem now, but likely to become a problem for the future" (41%). [

The spectacular quickening in population growth dates, only from the middle of the seventeenth century (Fig.22). Yet. Although data are unreliable, it seems that the annual rate of increase doubled between1650 and 1850, doubled again by the 1920s,.and has since doubled again. By 1970 it was 2.0 per cent per annum the total population has more than doubled during this century. and during the 1950s alone it rose by onb4ifth or nearly 500 millions - about the estimated total population in the mid seventeenth century The annual increase now exceeds 70 million person’s the increase rate persists at its present level, the world population will be multiplied six fold within 100 years, but if there is a continued rise in the annual rate of increase there may be several billion more people.

25. Human Population Growth Human Population Growth The Rate of Natural Increase Birth rate (b) − death rate (d) = rate of natural increase (r). birth rate expressed as number of births per 1000 per year http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/P/Populations.html

Index to this page The Rate of Natural Increase ( r The Demographic Transition The Story of Sri Lanka ... Looking Ahead Human Population Growth The Rate of Natural Increase ( r Birth rate ( b d ) = rate of natural increase ( r birth rate expressed as number of births per 1000 per year (currently 14 in the U.S.); death rate expressed as the number of deaths per 1000 per year (currently 8 in the U.S.); So the rate of natural increase is 6 per thousand (0.006 or 0.6%). Although the value of r is affected by both birth rate and death rate, the recent history of the human population has been affected more by declines in death rates than by increases in birth rates. The graph shows birth and death rates in Mexico since 1930. The introduction of public health measures, such as better nutrition greater access to medical care improved sanitation more widespread immunization has produced a rapid decline in death rates, but until recently there was no corresponding decline in birth rates. In 2007, r is 1.7%. (Data from the Population Reference Bureau.) This situation, resulting in a rapid rate of population growth, is characteristic of many of the poorer regions of the world.

Photograph: Getty Not everyone agrees the world is overpopulated but there is agreement that there are real issues with an expanding population , of which food supplies are just the most obvious. Data from the World Resources Institute (WRI) suggests that global population will increase by 34% by 2050 - an extra 2.3 billion people. To consider that the entire global population was 2.5 billion in 1950 gives an idea of the challenges which lie ahead. It's intuitive that more people require more resources and use more energy, but when you consider many countries are still developing, it explains why the relationship between the two isn't linear. For example, China's population rose by 15% between 1990 and 2005, yet

They include Belarus, Bulgaria, Germany, Japan, Poland, Russia, South Korea and Ukraine. - Slower population growth in many developed countries has led to a higher proportion of older people. In these economies, 22 percent of the population is already aged over 60, a proportion projected to reach 33 percent in 2050. This has raised concerns about economic sustainability and the future of pensions.

32. THE IMPACT OF POPULATION GROWTH ON FOOD SUPPLIES AND ENVIRONMENT Pimentel, Food, Overpopulation, Human Overpopulation, Science, Ecology, Economics, Environment, and Politics. http://www.dieoff.org/page57.htm

Home http://jayhanson.us/america.htm IMPACT OF POPULATION GROWTH ON FOOD SUPPLIES AND ENVIRONMENT by David Pimentel, Xuewen Huang, Ana Cordova, and Marcia Pimentel Presented at AAAS Annual Meeting, Baltimore, MD, 9 February 1996 Submitted for publication to Population and Development Review , New York, NY, USA As the world population continues to grow geometrically, great pressure is being placed on arable land, water, energy, and biological resources to provide an adequate supply of food while maintaining the integrity of our ecosystem. According to the World Bank and the United Nations, from 1 to 2 billion humans are now malnourished, indicating a combination of insufficient food, low incomes, and inadequate distribution of food. This is the largest number of hungry humans ever recorded in history. In China about 80 million are now malnourished and hungry. Based on current rates of increase, the world population is projected to double from roughly 6 billion to more than 12 billion in less than 50 years (Pimentel et al., 1994). As the world population expands, the food problem will become increasingly severe, conceivably with the numbers of malnourished reaching 3 billion. Based on their evaluations of available natural resources, scientists of the Royal Society and the U.S. National Academy of Sciences have issued a joint statement reinforcing the concern about the growing imbalance between the world's population and the resources that support human lives (RS and NAS, 1992).

33. World Population Growth From R.L.McConnell Daniel C. Abel, Environmental Issues. Measuring, Analyzing and Evaluating http://www.wou.edu/las/physci/ch371/lecture/popgrowth/howlong.htm

World Population Growth. Population growth is basic to any environmental issue. Humans exert a profound physical impact on their immediate, regional and global environment. Space considerations We take up space that was once forest, wetland, prairie or mountainside. While the space taken up by each individual varies. For example, it can be minimal such as in the cities of India or considerable such as in the late 1990 American single-family home which averages 2100 ft (0.05 acres or 0.02 hectares). Food considerations We need to eat so land is required for agriculture. Much of that land is irrigated and fertilized with industrially produced fertilizers. Meat production produces animal wastes that can result in water pollution via runoff. Transportation Roads cover permeable land with impervious paving and generate polluted runoff. They impact animals by dividing animals habitats which may accelerate species loss. Roads also provide human access to wilderness and forestland resulting in alterations of these areas. Waste Production People in developed countries produce huge amounts of sewage as well as commercial, residential and industrial wastes. In the U.S. alone each individual produces about 725 Kg of municipal waste each year (exclusive of mining and other industrial waste.)
