NASA data verify China's contribution to greening efforts

Standing on a hillside, 46-year-old ranger Huang Xiaobin looks down at the lush landscape that surrounds his village in the remote mountainous areas of the southwestern Jiangxi Province. Terraced slopes that were once barren are now filled with cedars and pine trees.

The landscape has changed a lot since Huang's grandfather, the first ranger in his family, took the job in 1951. At that time, the fields were just sparsely dotted with bushes.

Inspired by the idea of turning barren hills to green ones, Huang's father and Huang picked up the batons in succession.
