Environmental Challenges: Pollution, Climate Change, and Biodiversity Loss
Greenhouse Effect and Global Warming
The greenhouse effect is a natural phenomenon where the atmosphere absorbs some of the Earth’s energy, preventing it from escaping back into space. Human activities, primarily the release of greenhouse gases like CO2, intensify this effect, leading to global warming.
Consequences of Global Warming
- Melting polar ice caps and rising sea levels
- Loss of biodiversity due to temperature changes that many animals cannot adapt to.

The Spanish Ancien Régime
The Ancien Régime in Spain, a product of feudalism’s decline, persisted until the Portuguese Liberal Revolution of 1789, coinciding with the French Revolution. Politically, under Hapsburg and Bourbon rule, the system fluctuated between authoritarianism and absolute monarchy. Governed from Madrid, the political-administrative structure, influenced by the Nueva Planta decrees, lacked a unified Spanish state. Different kingdoms coexisted under the king’s rule.

Influencing Factors
Physical Factors
Physical factors, though less impactful than in the past due to technological advancements, still play a role in shaping rural areas. These include:
- Relief: Abundant high altitudes and steep slopes hinder mechanization and contribute to erosion.
- Climate: Low and unpredictable rainfall (thunderstorms, hail), extreme temperatures (intense heat and cold), and varying degrees of aridity characterize much of the area.
- Soils: Predominantly poor quality

Tourism in Spain
1. Factors in Spanish Tourism Development
The word “tourist” emerged in Britain during the late 18th century, referring to individuals who embarked on journeys for cultural enrichment or leisure.

Demographic, Economic, and Environmental Issues
The Spanish countryside faces numerous challenges, including:
- Demographic decline: An aging and shrinking rural population with limited skills.
- Economic stagnation: Over-reliance on agricultural activities and limited diversification.
- Environmental degradation: Deforestation, soil erosion, overfishing, and water pollution.
The agricultural sector’s contribution to GDP has decreased to 3%, and its share of foreign
