Stop the Construction: Save the Son Doong Cave!

Help protect the world’s largest cave, Son Doong Cave (and Hang En Cave, the world's 3rd largest cave) - in the UNESCO world heritage site, Phong Nha - Ke Bang National Park, Quang Binh Province, Vietnam.
The Government of Vietnam needs to act immediately to stop a proposed cable car construction project which could lead to Son Doong cave collapses and will threaten the pristine cave with further development. The proposed cable car project to Hang En (the world's third largest cave) that has been supported my Prime Minister of Vietnam Nguyen Xuan Phuc in August 2017 also needs to be stopped because the bad impact of mass tourism on the core area of Phong Nha Ke Bang National Park is obvious if it is built.
The project proposed initially by Sun Group has been stopped for 2 years due to a huge opposition, and now back with the new investor - FLC Group. The FLC Group was approved by the provincial government to conduct surveys for the construction of a cable car system to the Son Doong Cave (and now to Hang En Cave)
These cable car projects must be stopped before it has a huge and damaging impact on the Son Doong Cave/ Hang En Cave and the ecosystem of the entire Phong Nha - Ke Bang National Park.
