Geo. human and ecosystem.
Paulina Czerwinska I H. "Human activities always cause permanent changes to ecosystems." Discuss with reference to examples. Opinion essay. Ecosystem consist of the animals, plants and the environmental conditions of an area. Is a community of living and non-living things that work together. If ecosystems were completely disrupted, then life would change drastically for the humans and animals in the world. Some people might not think that it is worth it to try to save the different ecosystems. However, it is very important. Nowadays, almost none of us, realize that human activity really cause significant damage to ecosystems. I agree that our activities cause permanent changes to ecosystems and I will try to cite some examples, supporting my thesis. To begin with humans often need to burn fuels or produce certain chemicals to sustain a variety of activities in society. Burning fuels and manufacturing chemicals also can produce pollutants, including wastes like trash or hazardous chemicals and atmospheric pollutants like sulfur dioxide or nitrogen oxides. Pollutants can kill or harm organisms in ecosystems, gradually causing the ecosystem to deteriorate. Secondly, we sometimes hunt and poach animals for food, sport or their supposed medicinal properties. They are constantly being hunted for their furs and skin. Many have become endangered because of this. People do not

Extreme Environment Report - Cumbria. The aim is to investigate a cold and high attitude environment in high mountains in non tropical latitudes.
EXTREME ENVIRONMENT REPORT - Cold and High attitude 1.0 Introduction .1 Hypothesis and aim: .1.1 The aim is to investigate a cold and high attitude environment in high mountains in non - tropical latitudes. .2 Back Ground information: 1.2.1. These environments are relatively accessible and tend to be viewed as inhospitable to human habitation. Despite this, they provide numerous opportunities for settlement and economic activities. This report examines the essential landscape characteristics of mountains that experienced glaciations during the ice age. It will also investigate the natural processed operating in this area, and the way in which people have responded to the opportunities they offer and the challenges they pose for management and sustainability. .3 Location: 1.3.1 The Lake District National Park is the mountainous region located in the north - west of England (54°35'N, 03°20' E), in Cumbria, just south of Scotland. It's the largest National Park in England and Wales, and the second largest in the United Kingdom. It covers approximately 2,290 km/ 800 square miles. The landscape offers attraction like the highest mountain of England (Scaffel Pike, 978 m). There are 88 water basins throughout the District, 19 are the main lakes, the largest and most central of these is Windermere. The most important cities are located in the eastern part of the region;

Grade 12 Globalization Fieldwork Study 2008 - Basel Philip Mannas word count: Table of Contents Introduction Aims of Investigation Location map of Switzerland (in the world) Location Map of Switzerland (in Europe) Detailed Map of Basel/site locations definitions of globalization Hypothesis Methodology I Methodology II Analysis of results Evaluations and conclusions Bibliography Appendices A - Random Aisle sampling results B - Price - distance results, Spearman's Correlation Coefficient C - Car Survey raw data D - Random aisle Food Survey raw data E -Land Use Maps F - Regional Map of Switzerland Introduction Basel's location in the heart of Europe, with its land-locked status suggests that it is a country that has evolved around contact and interaction with its neighbors. It is the third largest city in Switzerland and lies at the Rhine which was the initial element for its economic growth and development1. As a result, Switzerland is a country that embraces the need for international co-operation, and acts as good example of a country that interacts with globalization.

With reference to specific examples, examine the advantages of migrations
With reference to specific examples, examine the advantages of migrations Migration can be defined as a movement and in human terms usually refers to a permanent or semi permanent change of home. In spatial aspects there are two main types of migrations: internal and external migration where internal migration is the movement within a country whilst external migration is the movement across national boundaries and across countries. On the other hand, in temporal aspects there are many types of migrations: permanent, semi-permanent, seasonal, daily, forced and voluntary migration among which the last two are the most prominent. Voluntary migration can be defined as the free movement of migrants looking for an improved quality of life and personal freedom (jobs, improved housing e.t.c) whilst forced migration is when people have to leave their country because they are forced away from it for reasons beyond their control (wars, famines, e.t.c) In this essay I will attempt to examine the advantages and disadvantages of voluntary and forced migration (internal and external) concerning both the host and origin nations with references to the Philippines, United Kingdom, China, India, New Orleans and Darfur. The Philippines is the world's 12th most populous country in the world with a population of 92 million people of which 11 million live abroad (around 11% of the population).
Effectiveness of strategies designed to reduce disparities
Evaluate the effectiveness of strategies designed to reduce disparities Disparities can be referred to differences, bias and unequal in gender, jobs, wealth, or contrast between rich and poor. Scales of disparities can be classified into regional, national or global. In recent years, inequalities in wealth and economic growth have increased both between and within countries - from one area to another and among different groups of people. However, various ways to reduce disparities are introduced in different countries, consisting of government investment on social development, foreign investment that mainly focuses on economic integration, different kinds of aid, structural adjustment policies and easier access to markets. Papua New Guinea is an example to demonstrate how government aid and foreign investment have reduced disparities. It is the eastern half of the island of New Guinea, which situated to the north of Australia. Before European colonization, most people earned a living by small-scale subsistence farming. However, when machinery was developed in 1850s, the indigenous technology for producing the oil was made redundant and eventually led to village producers working on plantations established by the Europeans. After the World War II, Australian aid led to the growth of an extremely large government sector of employment, stimulating a rapid increase in the rate
Changes in Tourism
Geography Essay- Factors Affecting Tourism Describe the changes in the growth in tourism in recent decades. Explain the factors responsible for this. In the 1950s, there were 25.5 million of international tourist arrivals and mostly were Europeans, which were 16.8 million arrivals. However, in the 1990s, international tourist arrivals increased to 455.9 millions. The significant changes were 280.6 million arrivals were from middle-east and 57.7 million arrivals were from Asia-pacific. First of all, transportation is one of the major factors seriously affecting each country's tourism because countries without high efficiency of transportation, it would lower tourists preferences to visit a specific country. For instance, development of the High-speed rail industry in Europe attracts more tourists from Europe continent of even internationally because High-speed trains were also quite fast, which can travel more than 250km/h in average. And travelling by trains was relatively cheaper compared to travel by planes because roundtrip tickets from London to Paris in Euro star cost $1575.6 HKD. However, air roundtrip tickets from London to Paris cost $2484 HKD in British Airways. Secondly, development of infrastructure- both roads and airports in More Economic Developed Countries (MEDCs) and Less Economic Developed Countries (LEDCs) were improving, which allowed more large sizes of
Enviromental Quality
To what extent do you agree that the global physical environment is showing healthy signs of improvement, following better international co-operation and use of cleaner technology? With an ever increasing population, quickly industrializing BRIC (Brazil, Russia, India, and China) Economies and growing Global Superpowers, world energy demands are increasing exponentially. To meet the demand for this more energy is needed to be supplied, historically normally fossil fuels such as Oil, Gas, and Coal power stations would have been the solution but now, due the seen effects of climate change and the potential problems we would face, cleaner 'green' technology is being utilized. In most MEDC's, the green energy industry is one of the fastest growing sectors of the economy (in terms of investment), and progress is being made as has been seen with the construction of; massive wind farms (London Array), Solar Plants (California), Hydroelectric Dams (3 Gorges Dam) and even the switch back to Nuclear power (although this does have its own problems on the global physical environment in terms of pollution of Nuclear waste). Whilst this change is positive and is improving the global physical environment, there are still huge industries not wanting to conform to cleaner technology due to the increased costs. Examples of this are commonly the massive multinational cooperation's who exploit

Standard Level Outline the contrasting attitudes of the Malthusians and neo-Malthusians to the current food supply situation. Malthusians: • population increase • outstrip resources because food suply increase arithmetically Neo-Malthusians: • limited resources keep population growth in check and reduce economic growth To what extent is it realistic to recognise "three agricultural worlds"? Therefore that no major changes for a country occur, the three agricultural world are very stable. Still it contains some inaccuracy as it is the majority what is looked at. When considering the poor have-nots, not all people in this country are unable to produce enough food for themself. There might still be some people who might have very sufficined land for production. Discuss the advantages and disadvantages of the Green Revolution. Advantages Disadvantages Increase of crop yields => reduce LEDCs Fertiliser is costy => price production increases Shorter growing season => more crop yields produced Middle and higher income farmers benefut nire => increase rural to urban migration Farmers income increases => purchase of machinery, better seeds, fertilisers and pesides Mechanisation has increased rural employment Local infrastructure upgraded => stronger market approach Some HYUs have an inferior taste Employment in input in industries Problem of salinisation has
Case study on Aral Sea
Aral Sea Introduction Aral Sea is located in the Central Asian Republics of Uzbekistan and Kazakhstan, with the southern section located in the Autonomous Republic of Karapakalstan. Aral Sea is a large inland sea that has no outlets. The Sea is connected to two rivers that supply the sea with water. These two rivers consist of water that is from glaciers. One river is called Amu Darya and the other Syr Darya. Amu Darya is 2,580 km long and flows northwest from the sources in the snow-capped Pamirs. The waters from this river are used for irrigation in Turkmenistan and Uzbekistan. Syr Darya is 2,220 km long and it is also used extensively for irrigation. It is formed in the Fergana Valley by the confluence of the Naryn and Kara Darya rivers. When combining the two rivers we see that it is quite large with a combined annual flow of 111 cubic km, this is higher than the river Nile which is only 90 cubic km. The fresh water from these two rivers held the Aral's water and salt levels in perfect balance. Even though much of the water in the river is lost to evaporation, transpiration and seepage as the river flow across the desert. There is still enough water in the river to maintain the Aral Sea normal surface area. But more recently due to human intervention not enough water is entering the sea. This is because locals tried using the rivers as an economy advantage and started
