The Lhalu Wetland National Nature Reserve, known as the "Lungs of Lhasa," has undergone an incredible transformation. Through 30 years of conservation efforts and an investment of 8.5 billion yuan (around $1.2 billion), the wetland's vegetation coverage has increased from 60 percent to over 95 percent. It now provides a habitat for over 200 animal species, including the endangered black-necked crane. This urban oasis not only improves air quality but also offers a beautiful recreational space for residents and visitors, demonstrating Xizang's commitment to ecological progress.
