U guys should stop visiting caves from now, too. Wild trade ban is still not enough.
Thats why we wont die easily just bcs of some kind of virus inside the caves like CNese![]()
Nothing to do with food habits, blaming it on bats...while South China is the realm of bats and caves, is no more absurd than trying to ban snow in Kattegat!
World's Largest Cluster of Sinkholes Discovered
Forty-nine sinkholes were found in China by researchers, who say the features have more secrets to tell.
PUBLISHED November 30, 2016
Scientists in China announced a major new discovery this week: 49 massive sinkholes that were previously unknown, representing the highest natural density of the phenomenon in the world.
Government researchers discovered the sinkholes during the course of a four-month survey in the Qinling-Bashan Mountains, which are located in the Hanzhong area of northwest China's Shaanxi Province.
The 49 sinkholes are clustered in a 230-square-mile patch of land within the 2,000 square miles that were surveyed.
The largest of the sinkholes has a diameter of 1,706 feet and a depth of 1,050 feet.
The scientists also found several species of rare plants and Chinese giant flying squirrels, which have striking red fur.
The team suggests the holes likely formed slowly over hundreds of thousands of years as underground water dissolved carbonate rock, such as limestone, under the surface. It's the same process that is frequently seen in other places around the globe—irregular landscapes commonly known as karst areas.
French cave explorer Jean Poutasi inspected one of the newly discovered sinkholes and called it "the world's most beautiful sinkhole," according to Chinese media.
Local officials hope that public interest in the sinkholes, along with the rugged beauty of the surrounding landscape, may attract tourists to the region. They also say they are starting to work on granting protection to the sites, which might contain geological records of past climates.
Sinkhole expert Randall Orndorff of the U.S. Geological Survey previously told National Geographic that a sinkhole is basically any collapsed or bowl-shaped feature that's formed when a void under the ground creates a depression into which everything around it drains.

Sinkholes can open up gradually or rapidly, sometimes swallowing buildings or vehicles and even causing deaths. Without advanced sensing techniques like ground-penetrating radar, sinkholes often leave little indication on the surface as they form, until the soil above them collapses. Occasionally, however, they are preceded by cracks or slumping.
Sometimes landslides are mistaken for sinkholes, but a true natural sinkhole requires that a void form from below. Certain human activity—such as construction or poor water management—can also cause artificial sinkholes, sometimes to devastating effect.

And here, who are the one who go inside...
Inside the vast Chinese caves where SARS may have originated and a new species of flesh-eating fungus has been discovered
There are countless kilometres of claustrophobia-inducing underground caves in Yunnan, full of bats and home to a newly discovered species of fungus

Southwest China is riddled with caves. The sheer number of them means most remain unexplored, despite caving becoming increasingly popular in China. The cave system is home to all sorts of wildlife, and now one more previously unknown species has been added to the list.
Dr Peter Mortimer, a South African mycologist and professor at Kunming Institute of Botany, is an accomplished caver and climber and he took us down one of his projects about 20km north of Kunming – Yanzi Dong, or Swallow Cave.
Rappelling using a climbing rope took us into the main chamber of the cave. Ropes are the preferable mode of transport to scrambling down a rotten tree trunk dropped into the shaft, as locals used to do to harvest stalagmites in the cave. Delicate Xylaria fungus now covers the trunk entirely, its fluorescent glow in the headlamp made the descent feel like a dive into oceanic depths.
Spooked bats flapped around and the air was thick with the smell of their excrement. Down on the floor, masses of ghostly white millipedes feasted on thick piles of bat droppings. On the walls, cave leeches tried to creep up on the sleeping bats. In the light of headlamps the leeches looked blue.
Mortimer found a fluffy white ball with bones sticking out of it – a dead bat being devoured by a fungus. He packed the carcass into a plastic bag.
“I will get its DNA sequenced – this fungus may well be new to science,” he said. Yunnan Province has the highest biodiversity of fungi in the world and Mortimer’s research group has identified over a thousand new species.
Caves can harbour very sinister inhabitants – fungus Histoplasma capsulatum, which lives on bat droppings, can cause the potentially fatal “caver’s disease” – histoplasmosis. Also, the virus which caused the 2002 SARS (Severe Acute Respiratory Syndrome) outbreak is believed by some experts to have originated from bats in a cave in Yunnan.
Stumps of cut stalagmites indicate how far the locals have gone, but without specialised equipment one can go only as far down as the main chamber. The lower levels of the cave are accessible only by a series of rappels through a narrow shaft recently discovered by Mortimer.
“This part of the cave is totally safe,” said Mortimer after we had explored the thankfully wide corridors and spacious, stalactite and stalagmite-filled main chambers. “Let’s go deep down to the underground river, it is a much more full-on experience.”
It is very easy to run into serious trouble in these caves. The rappels took us through piles of giant blocks held together by their own weight or glued into the walls with mud.
Everything was caked with mud.
“This is like a reverse birth” laughed Mortimer, as he squeezed down through a particularly narrow and muddy tunnel.
We rappelled and squeezed down into another chamber – a stream flowed into it before vanishing into a wall. The low ceiling was studded with large, loose blocks. We were now about 100 metres below the surface.
“We have once tried to follow this stream up, we could see the light – there is an opening – but it was blocked by rockfall.” Mortimer said. “Let’s try to follow the stream down for a bit.”
We did not get far – very soon the ceiling and the floor converged to such an extent that Mortimer decided to turn around. It is rainy season and a rainstorm can flood this passage in minutes.
“We should come back later,” Mortimer said. “It would be great to find an exit from here, this would save us going up the ropes to get out.”
Ascending a vertical rope requires considerable physical effort as well as technique. In the muddy, narrow darkness, where a thrashing, tensioned rope or a wrong placement of one’s foot may trigger a rockfall, it was an uncomfortable, and seemingly interminable, experience.
Driving back to Kunming, Mortimer kept pointing out limestone formations in the surrounding mountains: “There are caves there also, all worth exploring.”
Chinese cavers have been exploring caves in Yunnan and neighbouring Guizhou for a while and there is a caving club in Kunming.
“Those guys are legit,” Mortimer said. “They can take you on a real caving adventure. There is an underground river in Guizhou that you can run in a raft, for two full days, all inside a cave system.”
Our brief foray into Swallow Cave was quite an adventure already – less than two days later, when we were safely back on the surface, a minor earthquake rattled Kunming. We wondered how many loose blocks it dislodged down below.
The bat-eating fungus we found turned out to be a very unusual beast indeed. The DNA sequencing results showed it was a completely new species, related to the famous Cordyceps sinensis, which infects caterpillars and is highly prized in Chinese traditional medicine, but this was the first time the fungi of this family was found to be feeding on mammals.
This find surprised and excited even Dr Mortimer.
“Molecular evidence shows it to be very isolated from its nearest relatives, and it is also morphologically totally distinct from anything I have seen before,” he wrote.
Yunnan’s caves, so numerous and accessible, are full of surprises and discoveries.
