Outline the causes and effects of one movement of labour from one region to another.
Charis Ow Mr Ben Hough Global Interactions - HL extension Economic interactions and flows Outline the causes and effects of one movement of labour from one region to another. Unemployment has been a serious issue occurring in many regions such as South Asia, where population is growing rapidly and its undeveloped economies -further elevating unemployment rates. Over the years, individuals struggle to look for suitable occupations up to the extent of migrating overseas due to many reasons. There are many causes of the movement of labour from one region to another -one of them is the low wages from their origin which pushes them to look for a better one as it does not pay well enough for them to support their families. For example, LEDCs such as India and Bangladesh would opt for a better lifestyle as they commonly perceive that working overseas would help them to live a more improved lifestyle. In addition to that, labour workers might find that there are better paid wages in other regions such as South East Asia and the Americas so that they could support their family -providing better food and necessities. Besides that, rapid economic development in these MEDCs attracts labour workers to migrate overseas as they believe the economy is more stable and there will be fewer fluctuations of inflation rates so that they would have less risky and long-term jobs.

examine the causes and effects of biodiversity loss in tropical rainforests Biodiversity refers to the variety and quantity of all forms of life on Earth such as plants, animals and micro-organisms. It is estimated that there are up to 30 million different living species on Earth and more than 50 percent of these species live in the tropical rainforests. (rain-tree, N/A) Tropical rainforests play and important role in the world's natural environment as well as human society, as they not only provide a safe home for numerous plants and animals and help stabilize the world's climate and nature, but also also are a great source for medicines and foods. However numerous lives in tropical rainforests are at risk due to human deforestation. Deforestation in tropical rainforests as the major cause of the tragic loss of biodiversity, mainly happens due to globalization and cattle ranching, hydroelectric power, migration and logging. As a consequence, the ecosystem is disrupted, soil is eroded, carbon dioxide levels are increased and the nutrient cycle is affected. Globalization and cattle ranching is one of the major causes of loss of biodiversity due to deforestation in tropical rainforests. Meanwhile, industrial countries continue to develop and the demand for cattle is rapidly increasing. Over the past 25 years, rainforests have been cleared from an area the size of the entire
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
To what extent could Keralas approach in controlling population group be applied to other parts of the world such as China, Nigeria or others?
To what extent could Kerala's approach in controlling population group be applied to other parts of the world such as China, Nigeria or others? Family planning refers to attempts to limit family size. Family planning methods include contraceptives such as the pill as well as drastic methods such as forced sterilization, abortion and infanticide. Kerala had spectacular success in limiting fertility without any strong regulation like China or even any financial support, incentives like other parts of India. Improving of the quality of people living in rural areas was considered to be a que of economic development. India was one of the first countries to attempt an aggressive family program as far back as the 1950's, but the results of such a policy have been mixed over the last six decades. While the population growth in India has slowed in certain provinces, it remains largely outpaced by continuing exponential population growth. The success of government-backed promotion of birth control has had limited by a number of factors, but the most important of these has been, according to the World Health Organization, which is largely supportive of family-planning programs: high level of illiteracy, poor access to information, poverty, and gender-based disparities serve as significant barriers to family planning. These include social stereotypes, lack of male involvement in family
Malthus got it right-we are doomed?
Malthus got it right-we are doomed? How far do you agree with this statement when discussing the population-resource relationship in the 21st century? In 1789 the Reverend Thomas Robert Malthus produced his 'Essay on the Principle of Population', which were based on two principles: first one being that the food supply would increase arithmetically over time, and the second one being that population would grow geometrically/exponentially. There would be a finite optimum population size (carrying capacity) in relation to food supply. So if the population would reach beyond this carrying capacity, it would lead to a decline in the standard of living - it would lead to war, famine and diseases. Nowadays, his prediction luckily is not the case. Since the 'Green Revolution' started in 1945, there has been an enormous increase in food supply provided by agricultural markets. The green revolution has enabled food production to keep pace with the increasing global population growth. The Green Revolution has provided some great benefits: "From 1950 to 1984, as the Green Revolution transformed agriculture around the world, grain production increased by over 250%"1 and "The world population has grown by about four billion since the beginning of the Green Revolution and most believe that, without the Revolution, there would be greater famine and malnutrition than the UN presently
Earthquakes: the Same Effects, but Differing Responses
Earthquakes: the Same Effects, but Differing Responses Earthquakes are the result of energy release within the earth's crust, as well as an immense natural hazard greatly affecting people - despite whether it is a more or less economically developed country. However, the way in which responses occur may differ between these regions. Underlying friction is the initial cause of earthquakes. As tectonic plates begin to shift, they are resistant and still held together by friction - whether with another plate, or the mantle. However, the force to shift the plate continues despite the friction against this force, until the force overpowers the friction and the plate moves; causing many impacts. Some include shaking and ground rupture; resulting in more or less damage to infrastructure, landslides and avalanches; which can occur if slopes are produced from the earthquake; and fires, if the earthquake causes damage to electrical power or gas lines. Other impacts include those caused by water - such as a tsunami; if the earthquake has caused sudden or abrupt movement of large masses of water, and floods; which occur from an overflow of water onto land. Lastly, humans can be impacted as earthquakes can cause injury and loss of life. Responses to earthquakes are affected by economic factors and types of technology available. Some immediate responses include rescue and medical teams
Impact of Polish migration to the UK
IMPACTS OF POLISH MIGRATION TO UK Migration has economic, social and political effects on both countries involved, i.e. the home and the host country. Some of these effects are symmetric in the sense that the positive effects for one country are mirrored one-to-one by negative effects on the other. Other impacts of emigration may be beneficial for both countries. It is difficult to find a specific feature of migration that has a negative impact at the same time on both countries, as in this case it would probably did not happen. It is difficult to give accurate figures about the total Polish-origin community in UK. It is estimated that currently it is composed of circa one million, including both those who are settled permanently and those who migrate only a temporary basis. But only around half a million are officially residents registered. Due mainly to personal and family reasons, the majority of the migrants are on a temporary basis. There may be also a difficult distinction between temporary and permanent migration, in general: is a polish emigrant to UK who intends to work in UK until his retirement age, permanent or temporary emigrant? The Polish migration to UK has its origins in the First and Second World War and the disastrous, bloody invasions suffered by Poland from Germany and the Soviet Union, respectively during the XX Century.

Pro-natalist Australia
Pro-natalist, Australia Background Information Australia is considered the most sparely populated continent in terms of the population density, 2.6 persons per km2. Like most of the developed countries are having problems with the issues of population, Australia is not exceptional. In fact, there has been the substantial fall in fertility rates since 1960s. Australia's total fertility rate has declined from 3.5 in 1961 to 1.73 in 2001, and in 2007 was 1.93 babies per woman with two child families the most common type. Also, there are concerns of the ageing of the Australian population, implying that there are fewer babies being born compared with a number of elderly population increased by life expectancy. Australia's population is ageing and the evidence for this demographic change is undeniable. The result of falling fertility, increasing life expectancy and the effect of the baby boomer generation moving through older age groups, has contributed to an increase in the number and proportion of people aged over 65 years. These trends are anticipated to continue and numbers of people aged over 65 years and proportions of people over 85 years are growing while proportion of the population aged between 15 and 64 years (labor force age) are falling. The main cause of the falling fertility rates is the increased empowerment of women. In Australia, greater numbers of females
China One Child Policy
Case Study China One Child Policy History China has the world's largest population, and it's cities are the most densely populated ones. It's policy is one of the most recognized policy, since is the most rigid of any country. The policy admites only one child per couple, and because of this it is called the "One Child Policy". Before 1949, before the communists had the power, China was at stage 1 of demographic transition model, and families had betwen 5 and 8 children. Also there was a high death rate, and a low life expectation. Infant mortality rate was also high, and so with death rate and birth rate, which means that the population was increasing at a very slowly rate. In these days, large families where encouraged, since the government followed a pro-natalistic population policy. Ten years later in 1960, the population increased dramatically to 100million people more, which determined China in the second stage of the demographic transition model. As a result improvements where made in medical services. In 1976, whith the death of Mao, the government decided to advocate voluntary population control to reduce the birth rate. China began to advice about limiting family sizes and to distribute information about the need to control the population growth. Finally in 1980, the One Child Policy was introduced, which provided benefits for couples which had only one
China's One Child Policy
Sasha Zouev Geography 09/11/05 China's One Child Policy China is the 3rd biggest country in the world in terms of land area. However in terms of population, China is by far the leading nation with a population of roughly 1,306,313,000 people (2005 est). Brief History of China's Population 1905 - 1978 China was founded in 1949 at a time when the country had a population of about 540 million. Within three decades the population was above 800 million. This record population boost from the 1950s to the 1970s fashioned a strong population momentum that is motivating China's population expansion in spite of already low levels of fertility. It is hypothesized that China's population will grow to some 1.48 billion. Nonetheless, all of this growth will take place during the next 25 years. In its most recent medium variant projection, the UN Population Division estimates that China's population will rise by 260 million between 1995 and 2025. This certainly causes a major crisis for China's food supply: within only three decades the nation will have to feed an additional 260 million people (equivalent to the total population of the USA). At the bottom of the Chinese population pyramid (see fig. 1) one can again see large associates that were born between 1985 and 1990. They are almost as large as the birth cohorts during the "baby boom" years. However, these large number of
