Grasslands

In general terms, a grassland ecosystem is characterized by huge open lands where the vegetation includes different types of grasses with very few trees. There are six main types: tropical grasslands, temperate grasslands, flooded grasslands, tundra grasslands, montane grasslands, and xeric grasslands. Tropical grasslands receive 50-130 cm of rainfall, while temperate grasslands receive 25-75 cm.

Key Characteristics of Grasslands

• Limited annual rainfall
• Dry climate
• Lack of nutrients in the soil
• Frequent droughts and uncertain precipitation
• Frequent forest fires due to semi-arid climate and flash lightning
• Poor vegetation dominated by grasses
• Home to a variety of animal species

Deserts

Most hot deserts occur in high air pressure areas where... Continue reading "Major Ecosystems and Environmental Concepts" »

The Rise of the Bourgeoisie and Industrial Change

What changes led to the industrial and bourgeois revolution?

The development of businesses increased the wealth of the bourgeoisie, surpassing the traditionally wealthy nobility and clergy whose wealth was based on land ownership. This shift in economic power led to increased social and political influence for the bourgeoisie, despite their unequal treatment as members of the Third Estate.

What were the two new production systems?

• Domestic System: Organized by merchants who supplied artisans with raw materials, collected finished products, and managed their sale.
• Manufacturing: Large workshops employing numerous artisans to produce weapons and luxury items like glass.

Population Growth and Agricultural

Economic Systems of the World

Subsistence System

• Based on the primary sector, families produce what they consume in small quantities. If necessary, they sell or exchange goods on the local market.
• Prevalent before the Industrial Revolution.
• Today, it is only found in less developed societies due to limited access to technology.

Communist System

• The state controls the economy, owning companies and deciding production (what and quantity), prices, distribution of profits, etc.
• Previously common, it is now used in Cuba, Laos, North Korea, Vietnam, and China.
• The Chinese system is a hybrid between communism and capitalism.

Capitalist System

• Means of production are privately owned (technology, companies, machinery, etc.). The motivation to make a profit drives

Disentailment (First Half 19th Century)

Historical Context

Beginning in 1836, the disentailment was driven by Juan Álvarez Mendizábal, Minister of Finance in the liberal government. This reform aimed to modernize the Spanish economy and reduce the power of the Church.

Objectives

• Debt Reduction: Obtain revenue to reduce the massive public debt.
• Agrarian Modernization: Modernize agriculture by transferring lands from dead hands to private owners for exploitation.
• Weakening Church Power: Reduce the economic and social power of the Catholic Church, which owned vast tracts of land.

Consequences

• Economic: Public debt was reduced and state resources increased, but land distribution favored the wealthy, worsening inequalities.
• Social: Many peasants and small

Today I come to talk about a very important topic, what is pollution. Today many of the products we consume and the industries that produce them generate pollution. We find air pollution in the air we breathe, in our food, in our clothes and cosmetics… Furthermore, plastic has literally flooded our lives. Pollution is not a long-term problem but it is currently affecting each one of us, for example air pollution that causes respiratory diseases, or deforestation that kills our fauna and vegetation.

The accumulated waste in our seas has become tons and tons. All of our beautiful cities, with our beautiful beaches, our incredible market stalls, could disappear. That is why we must reduce waste, nuclear energy, oil ... All this can be achieved... Continue reading "sswsss" »

Global Systems

Distinguish space from place and explain why these concepts matter to geographers
Space – The physical locations of events and phenomena. Where things can occur often represented on maps
Place – Space is organized into places often thought of as bounded settings in which social relations and identity are constituted.
- For environmental invasive projects, such as pipelines it is important to consider the place and what social relations are ongoing in that space.

Role of population, consumption (affluence) and technology as drivers of environmental change – including the consequences of prioritizing one over others

More people, more resources needed, therefore more pollutants
Consumption(Affluence) – Consumption per person

Panama

• Panama also has the world's second largest free trade zone, the COLON Free Trade Zone at the mouth of the Atlantic side of the canal.
• The trip through the Panama Canal from the Pacific Ocean to the Atlantic Ocean will take a little less than one DAY.

Haiti and Mexico

• Haiti is classified as a(n) LOW economy by the UN.
• Mexico is classified as a(n) UPPER MIDDLE economy by the UN.

Latin America and the Caribbean

• By 2050, the population of Latin America and the Caribbean is estimated to reach about 725 million.
• Humid subtropical climates are found in areas of Brazil and URUGUAY.
• Peru has large deposits of silver, tin, lead, and COPPER.
• Coffee and maize (corn), fruit trees, and vegetables are typical crops grown in Latin America's altitudinal life zone

Growth of International Trade

Increased due to the growth in industrial production, the improvement of transport systems, and construction of tunnels and canals. Dynamite enabled the construction of large tunnels through mountainous areas and also made it possible to build huge canals.

Industrial Development in Spain

It was slower than in the rest of Europe. Foreign companies invested capital in mining. The most industrialized areas continued to be Catalonia and the Basque Country. The expansion of the railway network helped the growth of the iron and steel industry.

Anti-Colonial Protest

In some colonies, indigenous people revolted against European exploitation and the disregard for their traditional cultural values. In colonizing countries, socialist... Continue reading "Growth of International Trade and Industrial Development in Spain" »
