Understanding Global Population Dynamics

High Population

Megacities: Urban Hubs and Global Influence

A megacity is an urban settlement characterized by a very high population density and large size. These cities also play a crucial role in the international political and economic landscape.

Key Characteristics of Megacities

• High population density
• Often located in coastal areas, facilitating trade
• Heavy influence on culture
• Fluid transportation between areas

Challenges Faced by Megacities

Traffic Congestion and Infrastructure

Employment Opportunities

Global Economy

International business is transforming the world as never before. The decades following the establishment of the General Agreement on Tariffs and Trade (GATT) in 1947 witnessed unprecedented growth in international trade and investment. Companies focused more and more on the mass production of products and services to meet insatiable world demand. Since the 1980s, emerging markets provided new impetus to worldwide economic interconnectedness. These fast-growth developing economies—some two dozen countries including Brazil, India, China, and Poland—are experiencing substantial market liberalization, privatization, and industrialization, which are fueling global economic transformation. These emerging markets, located on every... Continue reading "The Impact of International Business on the Global Economy" »

Industrialization in the Basque Country

Bizkaia's Industrial Development

1. Beginning of Industrialization: Second half of the 19^th century.
2. Location: Barakaldo and Sestao, on the left bank of the Nerbioi Estuary, and in Bilbao itself.
3. Primary Industries: Iron and steel.
4. Other Industries: Shipbuilding, hydroelectrics, paper mills, textiles, fish canning.
5. Industry Size: Large-sized companies.
6. Advantages: Proximity to a port, high-quality local iron ore, and the existence of a traditional merchant class.
7. Investment Sources: Local and foreign investment (British, Belgian, French).
8. Financial Groups: Commercial banks (e.g., Banco de Bilbao), business corporations, the Bilbao Stock Exchange.
9. Worker Origins: Immigrants from different provinces of Spain.
10. Important

Interspecific Relationships in Communities

Interspecific relationships within communities include:

• Predation: One organism kills and feeds on another.
• Competition: Organisms compete for the same resources (can be interspecific or intraspecific).
• Parasitism: One organism benefits at the expense of another.
• Social Parasitism: One species uses another for its own purposes (e.g., mosquito eggs).
• Commensalism: One organism benefits from another's actions without affecting it (e.g., beetles or vultures benefiting from excrement).
• Mutualism: Two organisms live in harmony (e.g., clownfish and anemones).
• Inquilinism: One organism finds protection from another (e.g., coral).
• Symbiosis: Two species live together to survive (e.g., bees and flowers).

IMPERIALISM

The Causes of Imperialism

During the late 19th and early 20th centuries, increased production forced Great Britain and Germany to seek new markets outside Europe. This economic pressure, along with other factors, fueled the Age of Imperialism.

• Prestige and Power: European countries viewed colonies as symbols of international prestige and sought to control strategic locations for security and mobility in case of conflict.
• Economic Expansion: Population growth and industrialization in Europe led to unemployment, prompting emigration to colonies for work. Colonies also provided sources of raw materials and markets for manufactured goods.
• Scientific Exploration: Scientific advancements spurred geographic expeditions to uncharted territories

Coastal Management Strategies

Building a Sea Wall

A sea wall is a wall built on the edge of the coastline to protect against erosion and flooding. For example, waves in Porthleven are managed using a sea wall.

Advantages

• Protects the base of cliffs, land, and buildings against erosion.
• Can prevent coastal flooding in some areas.

Disadvantages

• Expensive to build.
• Curved sea walls reflect wave energy back to the sea, maintaining wave power and potentially increasing erosion over time.
• High maintenance costs.

Building Groynes

Groynes are wooden barriers built at right angles to the beach, such as the Hopton Sea Wall in Norfolk.

Advantages

• Prevent the movement of beach material along the coast by longshore drift.
• Allow the buildup of a beach, which acts as a
