Biodiversity, Climate, and Environmental Threats
The Wealth of Life: Biodiversity
We depend entirely on plants, animals, fungi, and microorganisms. They feed us, provide us with medicines and other goods that enhance the quality of our life and promise a productive and viable future. However, a quarter of all species on Earth may be lost in the next three decades.
Every year, we lose 1.5 to 2 percent of the remaining tropical rainforests due to slash-and-burn practices. 24 billion tons of topsoil are lost annually, and with over 90 million people

Alternating Current (AC)
Alternating current (AC) involves a cyclical voltage that repeatedly changes over time, starting at zero, reaching a maximum, decreasing back to zero, then going negative before returning to zero. AC power is generated

The Peninsular Plateau
The Peninsular Plateau is a high plain located between 600-800 meters. Formed in the Paleozoic Era by erosion of the ancient Hesperian Massif (which emerged during the Hercynian orogeny), the plateau was later deformed in the Tertiary Period during the Alpine orogeny. This resulted in three distinct units:
- Former Paleozoic Base: Located in the western peninsula, this

1.3. Rural Settlement and Habitat
The rural settlement and habitat in Spain have experienced significant changes. Rural municipalities are defined as those with fewer than 10,000 inhabitants, with semi-urban areas having 2,000 to 10,000 inhabitants and strictly rural areas having fewer than 2,000. However, this criterion is not definitive, as some rural settlements in southern Spain have larger populations.
The origin of rural settlements is influenced by physical factors like topography and water
