A breathtaking underground plant kingdom was discovered in Hubei province, China. Because of the local Karst landscape and humid climate, a sinkhole over 290 meters (951 feet) deep was formed, where a unique ecosystem has developed.
Inside the sinkhole you can observe palm trees, vines, moss, swallows, butterflies and other wildlife. For a very long time, the access to the sinkhole was possible by only scaling a long rope which allowed the hole to develop an independent eco-system.
This phenomenon is a clear example of the power of nature and how it is able to survive and adapt to any climatic and environmental circumstances.
