Sustainable Cities

Today, more than half of humanity lives in cities, and this figure is expected to rise to 6 billion by 2050. This requires a rethink of urban planning and management, as rapid urbanization puts unprecedented pressure on the environment and public health. Sustainable cities must be environmentally, economically, socially, and politically healthy, both for the current population and for future generations. These cities are based on four pillars of sustainability:

• Environmental: concerns the ecological footprint, resource consumption, and pollution.
• Economic: concerns job opportunities and attracting investment.
• Social: focuses on quality of life, public health, and social integration.
• Institutional: includes democratic participation

True or False Statements

1. The challenges for sustainable development are intergenerational equity, assigning duties, and interconnection. True
2. Chemistry helps ecology by creating future models to predict the consequences of environmental issues. True
3. Biology is the science that studies the interactions between living things and their environment. True
4. A population is the living and nonliving things sharing the same space and time. False. A population refers to a group of individuals of the same species living in the same area, not living and nonliving things. The correct term is ecosystem.
5. Life may not be able to exist without the heterotrophs due to that are the base that drives the entire ecosystem. False. Life may not be able to exist without

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

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

Technological Progress and Innovation

Technological progress was the very heartbeat of the Industrial Revolution. It was not a single invention that changed everything, but rather a continuous process of innovation. Macro-inventions, such as the steam engine or mechanical spinning machines, opened entirely new possibilities. These groundbreaking innovations were then followed by micro-inventions—smaller, cumulative improvements that refined and expanded their use.

In the textile industry, a series of pivotal inventions revolutionized the production of cotton, making Britain the dominant textile exporter by the 19th century. Key advancements included:

• The flying shuttle (John Kay, 1733)
• The spinning jenny (James Hargreaves, 1764)
• The water frame

Dams: Benefits and Drawbacks

Dams are massive structures built across rivers to control water flow. While they offer benefits like hydropower generation, flood control, irrigation, and water supply for human consumption and industry, they also have significant environmental and social drawbacks.

Benefits of Dams

• Renewable energy generation
• Reduced flood risk
• Water security for agriculture and urban areas

Drawbacks of Dams

• Ecological Impact: Alteration of river ecosystems, disruption of fish migration (e.g., salmon), loss of biodiversity, changes in water temperature and sediment flow.
• Displacement: Relocation of communities, often indigenous populations, leading to social and cultural disruption.
• Sedimentation: Dams trap sediment, reducing reservoir

Globalization's Impact on Economic Inequality

Globalization has created economic inequality between states. One way to analyze this imbalance is to consider each region's participation in the international division of labor. This categorizes countries based on their involvement in the manufacturing process.

Raw Materials

These countries are often the most underprivileged because raw materials have a low market value.

They often lack the industrial infrastructure to exploit these materials effectively. Major oil-producing countries are an exception due to the high cost of petroleum.

Manufactured Goods

Because goods production creates infrastructure and such products are worth more on the market, these countries become more developed. However, production... Continue reading "Globalization's Impact: Economic Shifts, Benefits, and Challenges" »

Key Milestones in Sustainable Development

The Club of Rome (1968)

• Created by scientists, economists, businessmen, and civil servants concerned about the way modern societies were developing their economies.
• "The Limits to Growth" (1972, MIT, Massachusetts Institute of Technology): This projection for the next 100 years makes clear that our economic model is not sustainable, primarily due to resource depletion and pollution.

First Earth Summit (1972)

As the UN wanted to address environmental problems, they created the Brundtland Commission, which published "Our Common Future" (1987). This report defined "sustainable development" as development that "meets the needs of the present without compromising the ability of future generations to meet their...

Early Workers' Movements and Social Change

First Movements Against Working-Class Exploitation

• Luddites (1811): Destruction of machines as a form of protest.
• Workers' Associations (Early 19th Century): Provided aid in cases of unemployment and illness; demanded better working conditions.
• Trade Associations (1834): Demanded the right to unionize, higher wages, shorter workdays, and child labor legislation.
