The article discusses how natural resources in Catalonia have been overused, leading to ecological problems. The researchers looked at mining, agriculture, tourism, and other activities impacting the environment. They found that the land and sea are being used seven times more than what is sustainable. Forests and urban areas are expanding, while agricultural land is decreasing. Air quality has improved slightly, but water ecosystems are still struggling. Biodiversity is at risk, and current environmental policies are not enough. The researchers suggest revising laws, promoting research, and educating the public to create a more sustainable future.
