7. 3 reasons why current immigration is different

First, a significant number of today’s immigrants have entered thecountry illegally, and thus their position is insecure.

Second, today’s immigrants are largely non-white. Race has formed a principal line of fragmentation within American society, and, as such, it threads its way insistently throughout the story of immigration. Race separated the experiences of voluntary immigrants in the distant past, for such minority immigrant peoples as the... Continue reading "Legal monism" »

Economic Crisis and Recovery in 17th Century Europe

Causes of the 17th Century Agricultural Crisis

In the 17th century, agriculture was the primary economic activity. However, it suffered a significant crisis due to several factors:

• Wars: Many areas were plundered, leading to a decrease in the rural workforce.
• Plagues and Epidemics: Frequent outbreaks significantly reduced the agricultural workforce.
• Urban Migration: Farmers migrated to cities to avoid taxes they could no longer afford to pay.
• Outdated Techniques: Agricultural productivity remained low due to obsolete technology.
• Bad Harvests: Adverse weather conditions led to years of poor crop yields.
• Subsistence Crisis: These factors resulted in lower productivity and a sharp increase in prices.

A greater biomass;

Higher levels of species diversity;

Better soil structure and greater water retention;

Lower pH;

Plant species will be taller and longer living;

Greater community complexity and stability/equilibrium;

Greater habitat diversity;

B Award [3-4 max] for human threats, [3-4 max] for natural threats

and [2-4 max] the consequences.

e.g. Great Barrier Reef off the coast of Queensland, Australia

Human threats:

• Tourism; coral is very fragile and easily damaged by divers’ fins, touching coral, or breaking bits off for souvenirs;
• Overfishing can disrupt the balance of species in the food chain;
• Inadvertent damage from anchors and pollution from boats;
• Run-off of fertilizers from sugar plantations on the coast;
• Sewage and pollution from coastal settlements

China: Population 1.3 billion growing rapidly - 1 child policy used in the past

Most population in middle/middle-high income. Therefore spend a lot on luxury goods - more than any other country. Manufacturing hub Fashion industry - open to overseas brands, willing to spend a lot (not price sensitive) GDP growing fast, huge economy, dynamic & successful TRADE - surpassed US as a trading nation, rely heavily on emerging markets such as Brazil for exports but these EM cannot compete with their huge success and dominance. E-commerce industry is huge - no Facebook Whatsapp or Google, they use their own, WeChat has 900 million users. Use phones for everything. “Belt Road Initiative” - extend trade routes & integrate the economy. Opportunities... Continue reading "China: Opportunities and Strategies for Doing Business" »

2. (a) Río Grande de Santiago: Geographical Characteristics

[4 marks]

Describe the geographical characteristics of the Río Grande de Santiago downstream from La Presa.

1. (b) Human Activity and Water Flow Through Systems

[2+2+2 marks]

Explain three ways in which human activity can reduce the time taken for water to pass through the system.

Causes of Deforestation

• Procuring land for cultivation
• Building houses and factories
• Making furniture, using wood as fuel
• Natural causes such as forest fires and droughts

Effects of Deforestation

• Increase in atmospheric temperature due to increased carbon dioxide concentration, leading to global warming
• Severe droughts and floods
• Changes in soil nature, water holding capacity, and soil erosion, leading to desertification
• Destruction of wildlife habitat, making survival difficult

Types of Forests in India

Reserved Forests

These forests are earmarked only for the production of timber. Grazing of animals and cultivation of crops are not allowed in these forests. About 54% of forests are grouped under reserved forests.

Protected Forests

These forests are protected from further depletion. The right of grazing and cultivation is allowed with certain restrictions. About 29% of forests come under protected forests.

Unclassed Forests

There are no restrictions in these forests. These forests belong to the government and private individuals. About 16% of forests are unclassed forests.

News about global warming and its devastating impact on endangered animal habitats is widespread. Many organizations are working tirelessly to protect these species. Animals like orangutans and polar bears are particularly vulnerable.

While many people are disconnected from wildlife, living in urban environments, it's crucial to recognize that human actions often contribute to the endangerment of these animals. Increasing pollution threatens all species, and we have a responsibility to protect them. We must take action, such as reducing deforestation and educating future generations, to safeguard our planet.

Zoos, while offering a glimpse into the lives of these animals, often highlight the limitations of their captive environments. Creating... Continue reading "Protecting Endangered Species: A Call to Action" »

Demographic Regimes

Old Demographic Regime: Characterized by high birth and mortality rates (often catastrophic due to epidemics, famines, and wars), resulting in limited natural growth. This was typical of pre-industrial societies before the 19th century.

Demographic Transition Regime: Initially features high birth rates but lower mortality rates due to improved food availability, hygiene, and health, leading to increased natural growth. Towards the end of the transition, birth rates decline, and growth slows. This regime was present in Europe after the Industrial Revolution. The population pyramid was progressive, indicating a large base of young people and a small elderly population.

Modern Demographic Regime: Mortality and birth rates stabilize... Continue reading "Demographic Regimes and Population Density" »
