Sand is, after water, the most sought after natural resource. It is an essential component in the manufacture of electronic devices and glass, and it is also used in bulk in construction. Rapid population growth and the mass development of cities have turned this material into a scarce commodity and a very lucrative business has emerged in trading sand. The theft of sand is a real threat to the environment.
Human activity and global warming are accelerating the extinction of species. As progress continues towards the necessary transition to a decarbonised and environmentally responsible economy, protecting the planet’s biodiversity and its natural ecosystems is more important than ever, especially in so-called megadiverse countries. These are territories that concentrate an extraordinary richness of species and a high degree of endemism – meaning species that exist nowhere else in the world. However, it is important to draw a distinction: a country may host many species and be highly diverse without reaching “megadiverse” status if it does not also meet this high level of biological uniqueness.

Wind energy is produced by transforming the movement of air currents into electrical energy. To harness the wind produced on land, enormous wind farms are built capable of extracting maximum power from this clean, renewable resource. Let us explain how it works.
