Volunteers flocking to NGOs dedicated to protecting mainland's natural resources
Officials had no answers when the International Olympic Committee in 1993 asked if China had any environmental NGOs.
But the situation has dramatically changed since China began lobbying to host the Games, with hundreds of thousands of volunteers now working to protect the mainland's threatened environment.
Lu Junmin, from the eastern province of Zhejiang, is a volunteer who recently returned home to Wenzhou city from the frozen Kekexili nature reserve on the Qinghai-Tibet plateau.
Mr Lu spent almost a fortnight at the plateau, distributing environmental protection handbooks, observing and documenting wildlife, and taking part in patrols to protect fauna from poachers.
Kekexili, an Inner Mongolian word meaning Cyan Mountains or Beautiful Maid, sits about 4,600 metres above sea level and is famous for its pristine ecological environment and extremely tough conditions.
