A opta minune a lumii? Proiectul uriaș ascuns sub Sahara, lung de 4.000 de kilometri

In the Sahara Desert, Libya has developed the Great Man-Made River, a vast infrastructure project designed to transport ancient underground freshwater to coastal cities. This system, initiated in 1984, consists of approximately 4,000 kilometers of underground pipes, drawing from deep aquifers, particularly the Nubian sandstone aquifer. The water, known as fossil water, has been trapped for thousands of years, dating back to a wetter climate in the region. The project has significantly impacted agriculture and water supply in Libya, allowing for the cultivation of crops in arid areas. However, the resource is non-renewable at a human timescale, with estimates suggesting it could last between 60 to 100 years at current extraction rates. The infrastructure has also suffered damage due to the Libyan civil war, raising concerns about its sustainability.
