61. Math In Daily Life -- Population Growth If birth and death rates stayed the same across the years in all parts of the world, population growth could be figured with a fairly simple formula much like http://www.learner.org/exhibits/dailymath/population.html

I n the last few centuries, the number of people living on Earth has increased many times over. By the year 2000, there will be 10 times more people on Earth than there were 300 years ago. How can population grow so fast? Think of a family tree. At the top are 2 parents, and beneath them the children they had. Listed beneath those children are the children they had, and so on and so on, down through each generation. As long as the family members continue to reproduce, the family tree continues to increase in size, getting larger with each passing generation. This same basic idea applies to the world's population. Exponential growth Population grows in the same way that money grows when it's left to compound interest in a bank. With money, growth comes through accumulating interest upon interest. The interest payments you accumulate eventually earn interest, increasing your money. With population growth, new members of the population eventually produce other new members of the population. The population increases exponentially as time passes. WORLD POPULATION Year Population A crucial difference between money and population is that money can increase without limits while population can't. Any population of living creatures is constrained by the availability of food, water, land, or other important resources. Once those resources are depleted, a population won't continue to grow exponentially. It will plateau, or even decline, as a result of disease or malnutrition. Unlike calculating interest, calculating population growth is an imprecise business.

Number of adherents of world religions: According to David Barrett et al, editors of the " World Christian Encyclopedia : A comparative survey of churches and religions - AD 30 to 2200 ," there are 19 major world religions which are subdivided into a total of 270 large religious groups, and many smaller ones. 34,000 separate Christian groups have been identified in the world. " Over half of them are independent churches that are not interested in linking with the big denominations. " Most people in the world follow one of the religions listed in the table below. Included is the name of the religion, the approximate date of its origin, its main sacred or ethical texts (if any) and its estimated numerical strength (both in absolute numbers and as a percentage of the world's population.) These data are based on census or public opinion data. Thus, a person is considered to be of a particular religion if they say that they are of that faith.

63. Overpopulation -- NOW A SCIENTIFIC CONSENSUS and the US National Academy of Sciences that resulted in a joint statement, population growth, Resource Consumption, and a Sustainable world, issued in http://dieoff.org/page75.htm

Home "Science Summit" on World Population: A Joint Statement by 58 of the World's Scientific Academies The growing world population The world is in the midst of an unprecedented expansion of human numbers. It took hundreds of thousands of years for our species to reach a population level of 10 million, only 10,000 years ago. This number grew to 100 million people about 2,000 years ago and to 2.5 billion by 1950. Within less than the span of a single lifetime, it has more than doubled to 5.5 billion in 1993. This accelerated population growth resulted from rapidly lowered death rates (particularly infant and child mortality rates), combined with sustained high birth rates. Success in reducing death rates is attributable to several factors: increases in food production and distribution, improvements in public health (water and sanitation) and in medical technology (vaccines and antibiotics), along with gains in education and standards of living within many developing nations. Over the last 30 years, many regions of the world have also dramatically reduced birth rates. Some have already achieved family sizes small enough, if maintained, to result eventually in a halt to population growth. These successes have led to a slowing of the world's rate of population increase. The shift from high to low death and birth rates has been called the "demographic transition."

64. THE IMPACT OF POPULATION GROWTH ON FOOD SUPPLIES AND ENVIRONMENT supplies for future generations unless the growth in the high standard of living, the optimum population should be than 2 billion for the world (Pimentel et al http://dieoff.org/page57.htm

Home 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).

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 15 in the U.S.); death rate expressed as the number of deaths per 1000 per year (currently 9 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 2003, r is 2.4%. (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.

70. The Population Institute - Increasing Awareness Of The Last year the world lost 26 billion tons of topsoil. This devastation was a result of three phenomena, each related to rapid population growth urbanization http://www.populationinstitute.org/teampublish/71_234_621.cfm

The Issue > Overview Overpopulation When future historians chronicle the progress of civilization during the 20th century, they will be struck by two demographic phenomena. They cannot fail to observe the unprecedented growth of human population during that era, and, in particular, the rampant increase of human numbers in the world’s poorest countries. Secondly, they will focus on the movement of people from rural to urban areas. This internal migration began during the industrial revolution, but gained its most significant momentum over the past 50 years. It took all of recorded history until 1830 for world population to reach one billion; by 1930 we were at two billion; by 1960, three billion; 1975, four billion; 1986, five billion; and in 1999 we crossed the six billion mark. Encouraging demographic progress has been achieved in the last 20 years. Fertility rates have declined worldwide – even in some countries and regions where the upward spiral of population growth appeared all but impossible to reverse. Advances in medical technology have led to remarkable extensions of human life in most of the world, as well as substantial improvements in reducing child and maternal mortality and morbidity. There can be no question that the world is paying a costly environmental and ecological price for this prodigious proliferation of human growth. Our forests are declining, our topsoil is eroding, our deserts are expanding, our climate is undergoing radical change. We are looking at resource shortages – including severe scarcity of water and food in many developing regions.

72. The Environmental Literacy Council - World Population In 2300 this page presents asnapshot of world population and recent population growth trends, and explains basic demographic concepts such as exponential growth. http://www.enviroliteracy.org/subcategory.php/248.html

Home About ELC Site Map Contact Us ... Food World Population in 2300 The United Nations Population Division (UNDP) released its first projection of population trends to the year 2300. According to its medium scenario, the UNDP predicts global population will increase from approximately six billion persons in 2000 to nine billion over the next 75 years. Global population will then decline to about eight billion by 2175 and then increase again to nine billion by the year 2300. Because population grows at exponential rates, small increases of decreases in the growth rate would result in significant differences in long term population trends. For example, in its low growth scenario, UNDP projects that global population could decline to 2 billion in 2300; under its high growth scenario, as many as 36 billion people could populate the globe. All of these projects have a considerable degree of uncertainty; they are based on current population trends, but the world could be a very different kind of place three centuries from now. After all, three centuries ago, the Industrial Revolution was many decades away, and it was another century and a half before Louis Pasteur published the germ theory, which led to a revolution in health and the increase in longevity that has led to the current increase in global population. The UNDP's projections are based on its revised predictions for global population trends over the next five decades. During the past fifty years, there was an unprecedented increase in global population as mortality rates declined almost worldwide. This rapid increase in population raised concerns that population growth in many developing countries would outstrip the countries' ability to feed their population. That concern, however, has been reduced because of another unprecedented trend: Developing countries are experiencing a transition from high to low fertility rates much faster than occurred in Western nations in the late 19th and early 20th centuries. Total fertility rates are declining almost worldwide. The concern in many developed nations is that total fertility rates have dropped so low that populations will begin to

Home Population Implosion, Graying of the Population, Population Reduction, and Negative Population Growth Graying of the population Population Reduction The world's population 'boom' is not a result of an increase in birth rates, but rather a decrease in death rates. Today more infants and children are surviving into adulthood, while adults are living longer. Since the earth's resources are finite, population must stop growing somehow. Fortunately, birth rates are declining, because no one wants to increase death rates. However, population momentum (the 'boom' of young people who are beginning their child-bearing years), and the agonizing slowness with which birth rates are coming down, means the population is still increasing. In the meantime, modern medicine is allowing people to live even longer - causing quite a dilemna: will humankind reach a point where having children is to be discouraged, even to the point of one child or no children families? What will the world be like with fewer and fewer children and more and more elderly people? Some people do not realize that the earth's resources are finite. Or they believe that God or technology will take care of it. They propose a giant pyramid scheme to continue to produce young people who would take care of the old people - leaving the question of who is going to take care of the young people when they get old?

World population hits 6 billion A baby born in Sarajevo revives the population debate By Julia Sommerfeld MSNBC The world's six billionth person was born Tuesday, according to the United Nations. NBC correspondent Dawna Friesen reports. Fatima Nevic kisses her son, who was symbolically welcomed as Earth's sixth billionth person Tuesday. For one thing, it means that the population of the world has doubled in less than four decades. Similarly, it means that a tenth of all the people who have ever lived are now alive. Yet it also shows how quickly the rate of population growth has slowed since the alarms about the consequences of overpopulation began sounding in the 1960s. Since 1992, the United Nations has had to push back its 6 billion estimate by almost two years. Will technology save us from overpopulation? U.N. demographers project 2.9 billion people will be added to the planet in the next half-century, fewer than the 3.6 billion added during the past 50 years. But, in contrast to 50 years ago, when populations were growing everywhere, growth is now primarily occurring in developing countries. The United Nations Population Fund and environmental groups like the Worldwatch Institute Zero Population Growth and Population Action International are concerned about what a growing population means for the environment and for the quality of life in developing countries.

In the 1970s the world will undergo famines; hundreds of millions of people are going to starve to death in spite of any crash programs embarked upon now. So predicted Stanford professor Paul Erhlich in his widely influential 1968 book The Population Bomb . It sold more than three million copies but its many predictions of global catastrophe never came true. Most famines in the 70s and 80s were in African countries saddled with Marxist governments or political turmoil. Has Erhlich admitted these errors? No, in 1989 he wrote The Population Explosion . Without comment on his past mistakes he merely moves them into the future again, like those who predict the end of the world. Erhlich wrote, The Population Bomb tried to alert people to the connection of population growth to such events...but society has turned a deaf ear. Meanwhile, a largely prospective disaster has turned into the real thing.... There still may be time to limit the scope of the impending catastrophe, but not much time.

Last year on October 12th 1999, the human population of Earth reached 6 billion. In my lifetime the population has doubled from 3 billion in 1959 to the 6,034,213,000 today. This doubling of population which occured over the last 40 years will never come close to happening again. The exponential growth of human population peaked in 1987. That year 87.01 million more people were added to the Earth. Since 1987, the population has declined on average by 2.1 million less people added per year. In this year of 2000 the population will increase by 60.1 million people. If we maintain this 13 year average of 2.1 million less people added per year, we will peak in population reaching zero population growth in 2029 with 6.90 billion people.
