Tropical Rainforest Case Study
Sasha Zouev IB, 16/11/05 Tropical Rainforest Case Study, Amazonia Introduction Tropical rainforest, temperate coniferous and deciduous woodland forests are the three main categories of forest type. Tropical rainforests are considered a much richer species that the other two, and temperate vegetation is one that grows fastest. The rainforest ecosystem is very weak and easily unbalanced, making this type of forest more "permanently destroyed" than the other two. The importance of tropical rainforests lies within the fact that they are the earth's richest source of life as they play a vital part in the earth's natural cycles of soil, water and air through the process of photosynthesis. In this case study we will be looking closely at the tropical rainforest in the Amazonia region of South America. Where is this Rainforest? The term, Amazon rainforest, is used to basically talk about the moist and broadleaved region of what is known as the Amazon Basin, which is around 7 million km squared and covers areas of mainly Brazil, Colombia, Peru and many more South American countries. This rainforest accounts for around 50% of the world's remaining rainforests. Amazonian rainforests contain the biggest and most species-rich tract of tropical rainforest that there is to be found. It is the world's greatest natural resource - the most powerful and bio-actively diverse
Examine the causes and the effects of biodiversity loss in the Tropical Rainforests
Examine the causes and the effects of biodiversity loss in the TRF Biodiversity can be defined as the variety of all forms of life on earth (plants, animals and micro-organisms). The tropics are the richest areas for biodiversity as tropical rain forests contain over 50% of the worlds species in just 7% of the worlds land. They account for 80% of the world's insects and 90% of its primates. Even though biodiversity benefits us humans in countless ways we tend to be oblivious to this fact and instead, the biodiversity on earth is gradually diminishing. There are many reasons for the loss of biodiversity and the most prominent include Globalization & Cattle Ranching, Hydroelectric Power (HEP), Migration and Logging. Similar to how there are numerous causes for the loss of biodiversity, these causes also have many drastic effects. As mentioned in the introductory paragraph, globalization and cattle ranching is one of the major causes for the loss of biodiversity. Globalization can be defined as the world coming together for trading purposes. This contributes to the loss of biodiversity as globalization is directly linked with deforestation. For instances, huge global corporations like McDonalds own countless amounts of cattle which are often located in deforested areas. In addition to this, much forest land in the Brazilian Amazon is also deforested in order to enable the
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
How far do Trotsky(TM)s own misjudgments account for his failure in the power struggle which followed Lenin(TM)s death?
"How far do Trotsky's own misjudgments account for his failure in the power struggle which followed Lenin's death?" Following Lenin's death in 1924, a power vacuum appeared for the leadership of the Communist Party in Russia. A collective leadership was proclaimed, however competition for individual authority between Trotsky, Stalin, Kamenev, Zinoviev, Bukharin, Rykov and Tomsky led to a fierce struggle for power, ending in Stalin's triumph and the beginning of his tenure as the leader of the Communist Party. The strongest contenders in the power struggle were Stalin and Trotsky, however a number of unfortunate decisions and lack of support on Trotsky's part, coupled with Stalin's tactics and power base, led to Trotsky's defeat and exile. It was the latter of the two factors that contributed more to Trotsky's ultimate failure, due to the fact that Stalin's initial position was stronger, and his opportunism allowed him to take advantage of Trotsky's misjudgments, thereby allowing him to take power. However, it is worth noting that the term 'misjudgments' is relative to the historian, since a number of Trotsky's unsuccessful decisions were deliberately made to avoid certain outcomes, therefore cannot accurately be termed 'misjudgments'. Trotsky, although he had a limited power base made up of mostly radicals and students, was in a position of adequate leverage immediately
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
Symbols employed in "The American Beauty" and their effects
Implications of the Roses in "American Beauty" The rose has long been used as an archetype in literature and films. This flower is the manifestation of absolute beauty for artist in different genres and cultures but also symbolizes love and romance presented in the most primitive way of human nature. In the film "American Beauty", the symbol of rose is weaved in throughout the movie and is used not only to manifest the aspects of beauty but also reveals each unique character and their role in society. The rose is first seen in the beginning of the film with the accompaniment of Lester's narration about his life and family relations. Alan Ball employs the roses in the beginning scene as a symbol for power and success which she tries to pursuit in her career and family. We see Carolyn taking care of the roses in the garden and with the absence of Lester while she is socializing with the neighbors; the audience realizes that she is the dominant figure in the family. The fact that the neighbor is praising the beauty of the roses indicates that Carolyn is the iconic figure in the Burnham family and that she is recognized as an important and successful person in society. The success Carolyn has in her life, portrayed by the beauty of the roses, further highlights Lester's lack of masculinity in both society and family, establishing the two contrasting characters right at the
Comparison of emma and charls in madame bovary
Madame Bovary Similarities and differences of Emma and Charles In the first part of the novel, Madame Bovary, written by Gustave Flaubert, there are two main characters introduced to us; Emma Rouault and Charles Bovary. These two characters marry and become the "Bovary's". They both have interesting characteristics that lead to being opposing characters. In part one, we come across several descriptions of appearance, personality, education, background, and attitudes; that help us analyze these. The novel starts off with an introduction of what type of person Charles was during his childhood at school and what his classmates thought of him. Since a very young age, Charles had always been a very educated and respectful person towards others but always showed to be very insecure. He was described as "[...] country lad [...] taller than any of us (pg15)". Therefore you can see that his class mates didn't really accept him because he was different as for his physical appearance, character and style of dressing. The narrator talks to the reader as a school mate which sat in his class and observed him very carefully, he is also described as a forgettable child which shows that his presence didn't remain in people's minds. During his school years, Charles tried his best to attain the best results he could as he had never received a primary education- They "[...] postponed sending

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
Enzyme Coursework. Investigation to find the effect of substrate concentration on the rate of an enzyme controlled reaction
Investigation to find the effect of substrate concentration on the rate of an enzyme controlled reaction Design Aspect 1: Defining the problem and selecting variables Investigation title: is the rate of an enzyme controlled reaction affected by substrate concentration? Background information Enzymes are often referred to as "biological catalysts", since they increase the rate of reactions in living organisms. Enzymes are also substrate specific, which means that only a specific substrate can fit into its active site (which is where the catalysing effect occurs) and as such, there are different enzymes which deal with different reactions (for example, protease breaks down proteins into amino acids) - this is the basis for the 'lock and key' theory. The stages of an enzyme controlled reaction are: ) Enzyme + substrate The enzyme and substrate are in solution together 2) Enzyme substrate complex A substrate has moved into the active site 3) Enzyme product complex The reaction has taken place, but the products haven't been released from the active site 4) Enzyme + product The enzyme and product are now in solution together (after the product was released from the active site) The rate of an enzyme controlled reaction are mainly affected by: temperature, substrate concentration, enzyme concentration and pH. By increasing the substrate concentration, there is a higher
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
