Water is becoming increasingly valuable at a rapid pace. As climate change pushes global temperatures higher, water—essential for sustaining life—is turning into a vital natural asset that humanity must cherish and protect. Our hope lies in the places where nature still offers its gifts in full splendor.
One such place is the Guarani Aquifer, a vast underground natural reservoir of water. It is one of the most significant sources of freshwater on the planet and is currently considered the third-largest reserve in the world, holding approximately 40,000 cubic kilometers of water. Experts estimate that it could supply the entire global population for up to 200 years.
The Guarani Aquifer lies beneath the surface of several countries—Argentina, Brazil, Paraguay, and Uruguay—which are fortunate to share this resource.
Together, these four nations benefit from an area of approximately 1,200,000 square kilometers, distributed as follows:
- 225,424 sq km in Argentina.
- 840,246 sq km in Brazil.
- 72,540 sq km in Paraguay.
- 58,545 sq km in Uruguay.
In Uruguay, the Guarani Aquifer feeds the thermal waters of all the country’s hot spring resorts. These waters, with temperatures ranging from 35 to 42 degrees Celsius, originate from underground layers formed approximately 140 million years ago. Rich in minerals beneficial to health, they are believed to have healing properties, particularly for bone and skin conditions.
This vast underground lake not only enhances the natural beauty of the region but also boosts its appeal to visitors. However, growing concerns are emerging as the aquifer faces increasing overexploitation. The countries that benefit from it are now focusing on its environmental protection.
Let’s hope that collective awareness prevails, ensuring its preservation, shielded from pollution and unchecked economic interests.
