Population Essay. Does mother earth have the capacity to sustain continued population growth
Population Growth Essay " Does mother earth have the capacity to sustain continued population growth" That is the question I am going to answer in the following essay. We will be looking at two persons who gave there opinion about the principal of population growth and their solutions. One called, Robert Malthus, the other person called Ester Boserup. They both differ a lot of each other in opinion. Boserup was more optimistic about it, although on the other hand Malthus was very sceptic and pessimistic. I will include their arguments and their way of looking at population growth later on, combined with my own view. Several facts are concurring about population growth. When the world would collapse of its own infirmity, it will be due different factors. One of them will be due global warming. This is also one of the arguments of Malthus which influences his credo1. Population growth is a very important issue for geographers now a day. These geographers are certainly divided into 2 groups. One group focuses more on the Malthusian-way of thinking and the other support Ester Boserups her ideas, which are more optimistic. Worries about population growth are not new. About 200 years ago, Malthus published a essay called; The Principal of Population Growth. His main arguments in this essay were about the geometrically grow of population, while the resources available to
Population Essay
"The new threat to the planet is not too many people but too few." Was once written by Michael Mayer. He claimed that the global population will rise to a peak and then sharply decrease. As we know at the moment it seems like there are already too many people on the world, leading to starvation, scarce natural resources, poverty, war and global competition for jobs. And it seems like the amount of people are continually increasing, but will it really last and will it be a problem? In Japan in fact the population is already starting to decrease, where the total fertility rate is only 1.2. That means that a woman in Japan will have an average of 1.2 kids in her life. One of the problems in Japan is that it is difficult to live there as an immigrant. This is due to the hard language and very few Japanese people speak English well. So it's not really attractive to migrate to Japan. And the women see kids the result for Japan is what's called an 'ageing population', where there will be older people, than younger people in the future. The picture beneath shows the current populations pyramid of Japan. As you can see, the life expectancy in Japan is high, as there are quite some people in their 85's-89's. What we can conclude from this pyramid is by the trend in it. [Source: http://www.nurse.or.jp/jna/english/nursing/images/pyramid.jpg] The number of kids in the groups of 0-15
Population in Brazil
Sasha Zouev Geography IB, 5/09/05 IB Case Study: Brazil Population, Distribution, Density Introduction: As one of the most commonly studied populous LEDC's in the world, Brazil certainly has very interesting features and patterns regarding its population and distribution. First of all, Brazil is the largest and most inhabited country in South America, and fifth in the world. Its 8,500,000 square kilometer land area borders countries such as Colombia, Venezuela and Bolivia. The aim of this case study is to examine, section by section, the different factors that affect Brazilian population growth and distribution by looking at areas such as geographical positioning, politics, history, and generate some sort of conclusion. Distribution: Brazil's population is mostly concentrated alongside the coast. Coastal states, with a sum area of about 35% of Brazil, in fact account for about 87% of the entire population. Brazil can often be divided into clear-cut social, geographical and economic regions (figure 1). Masking half of the country, the Northern area has the dense and tropical basin of the Amazon (largest rain forest and largest river in volume of water in the world). The northeast, which is the most economically handicapped region, relies heavily on agriculture as its main economic activity. The area that is the wealthiest, and contains half of Brazils total
Britain's aging population
Britain's aging population Countries with aging populations have higher death rates. This is the case in the UK as death rates are particularly high in some of the popular retirement resorts along the south coast e.g. Brighton and Dorset. Although such services as the NHS work well in Great Britain and good doctors and medicine are keeping the elderly healthy until a much older age, this means that as the retirement age remains at sixty and people are beginning to live for longer. This is increasing the ratio of the number of people of working age (15-60\4 years) to support each person of sixty and over. As figure 3A and figure 3B show the UK to have the highest ratio against other high ratioed countries such as France. The figures show a forecast for the years to come, increasing by twenty years each time. Nearly all the way through the UK is shown to be the highest; this is due to the baby boom of the fifties and sixties. The official years of the Baby Boom Generation (1946 through 1964) saw a marked increase in the number of births in the world. Here's how the birth rate rose and fell during the baby boom years in America: 940 - 2,559,000 births per year 946 - 3,311,000 births per year 955 - 4,097,000 births per year 957 - 4,300,000 births per year 964 - 4,027,000 births per year 974 - 3,160,000 births per year There have even been books made about the baby boom:
Population Case Study - Japan
Sasha Zouev Geography IB, 13/09/05 IB Case Study: Japan (MEDC) Population, Distribution, Density Introduction: Japan is a great example of an MEDC with a particular population pattern and distribution. The country, located on the western edge of the Pacific Ocean lies to the east of Asia and is made up of about 3,000 smaller islands. There are several large main islands including, from top to bottom, Hokkaido, Honshu (the biggest), Shikoku and Kyushu. Japan is also interestingly rated 10th in the world by population count and has an area of about 377,835 km². The aim of this case study is to examine, section by section, the different factors that affect Brazilian population growth and distribution by looking at areas such as geographical positioning, politics, history, and generate some sort of conclusion Distribution: Japan's population is mostly concentrated alongside the south and west coast (figure 1). Japan's population density is ranked 18th in the world, and has assisted in advertising very expensive land prices. From the years 1980 to 1987, prices of land in the six largest cities nearly doubled. This prevents many poorer families from ever purchasing or renting housing in the central cities. Because of this, daily transportation for many workers became a real lengthy hassle. For example some daily commuters had to travel up to four hours total to reach
Pro-Natalist China's population policy
Introduction: China has the largest world population, and with most of its cities densely populated. It has a policy which is most recognizable globally, as it is the most rigid compared to any other countries, this policy admits only one child per couple, and due to this fact it is named as "One Child Policy." s Background information on the Population: What was the problem? Due to the high fertility rate, numerous disasters such as pressure on resources (water, food, medical care, and housing) and a virus such as SARS will not spread as fast if the population in China declines. Causes of High Fertility rate: Before 1949, before the communists came into power, china was at stage 1 of demographic transition model, and had between 5-8 children per family. By the time, birth rate, death rate, infant mortality rate were all relatively high, and with a low life expectancy. This shows that the population was increasing at an extremely slow rate. Consequently, large families were encouraged, as the government followed a pro-natalistic population policy. 0 years later in 1960, there was a dramatic increase in population with approximately 100 million people more; this determined a change in demographic transition model from first to second stage. In addition, as a result, there were improvements made in some medical services. Due to the death of Mao in 1976, the government
Mauritius - Case Study Focusing On Population.
Mauritius - Case Study Focusing On Population Mauritius is a small island in the Indian Ocean just off the east coast of Africa. The island was discovered by the Portuguese in 1505 and subsequently colonised by a number of European countries (Britain, France & Holland) before gaining independence in 1968. The European colonies started what is the major economy in Mauritius today - sugar. After the abolition of slavery in Britain (when the island was under British rule) workers were brought from India, which created a wealth of ethnic groups. At the beginning of the 20th century the growth of population in Mauritius was relatively slow. Between 1940-1970 the population exploded and nearly doubled. The main reasons for this are cited as being a sudden drop in the death rate after the eradication of malaria, and an increase in general healthcare. Normally countries with a good economy will have a drop in birth rates after a drop in death rates, but not in Mauritius for various reasons. For example the main religions on the island - Hinduism, Islam and Catholicism - both opposed the use of contraception. Also the average marriage age was extremely low, as this is also a part of Hindu tradition and it also ensures a high fertility rate. In the 1970's the fertility rate was an amazing 6.2 children per woman and the population growth rate was estimated to be 3%, and the mean
The demographic transition model accounts for the rise and fall in population, the birth rate, death rate, population size and growth.
Population growth is ultimately decided by the amount of births and deaths, and the balance of the main inputs and outputs of population, inputs to the population being births and immigrants, outputs being the deaths and emigrants. The proportion to which is what really matters. The demographic transition model accounts for the rise and fall in population, the birth rate, death rate, population size and growth. Different cultures, society's and geographical places have different reasons for being either under or over populated. For example, the Philippines, a mainly catholic country, is very overpopulated, because of the religion of the vast majority of the country, they don't use contraception or family planning, and so families can end up having many more children than is the 'norm' for say England, where the average number of children per household is 2, whereas, in the Philippines the average number of children per house is 5, and so the population rises. However, in places like Canada, where the population is around 33,000,000 people, so why does Canada have a low population density? It's because Canada is such a large country, the whole population is distributed very sparsely and there are only 3.4 people in a km 2. Canada is in stage four of the DTM, this means that: * The birth rate is falling * The death rate is low * There is no population growth * And the
How far do physical factors affect global population distribution?
Global Population Distribution by Atif Khan 10S How far do physical factors affect global population distribution? Global Population Distribution is the spread of people across the world. It can be an even spread or an uneven spread, and it depends on physical and human factors. Human factors include transport, infrastructure, government and employment. Physical factors are climate, relief, water supplies, soil type and resources. Across the world's surface area, most people are living in only small sections of land. This is because not all land has an equal potential for life. Examples of countries with very large populations are India and China. 2 in 6 people across the globe are either Indian or Chinese! However, in a country such as Afghanistan this population density is much lower. We will first study the physical factors that affect population. We will begin with climate. Average Annual Temperatures are important factors of population distribution. If the weather is too hot or too cold, people won't be able to live there. However, if there are no extremes of climate like this, countries are more likely to do well. An example of this is Western Europe. However, extremes of climate are not the only type of climate to affect population distribution. If a country is cold, for example, people are usually more likely to spend money on housing to provide shelter, using up
Factors affecting rates of population change across the world.
Alex Calloway Factors affecting rates of population change across the world Throughout the world today, ones can see huge differences in rates of population change, from massive population growth rates to a gradual decline in population. There are some countries in the world today, where the rate of population change is extremely low and such a situation can occur for a number of reasons. When one reads of population growth or decline, it is impossible to avoid discussion of China's one child policy. However, this policy is an extreme violation of human rights and is limited to just one country and so should not form the basis of a discussion of population growth rates or as an example of a country with low growth rates. Instead, it seems apt to concentrate on those countries where government influence is not so draconian or tyrannical. Italy is one country with a negative rate of population change and does provide an example of many reasons why this situation can occur. Following the Second World War, Italy experienced a rapid process of industrialisation, geographically concentrated in the North, given Italy's current level of development and its late beginnings, it is simple to imagine how quickly the process occurred, as this graph, taken from www.thetimes.co.uk, shows. This development gave the citizens of Italy much improved health care provision, which in turn
