A couple's mission to green a desert

Tubbat rises with the sun and hops on his motorbike to ride 30 kilometers to tend to a saxual forest that was once desert.

The 65-year-old and his wife, Tosontsagaan, have spent 15 years beating back the desert in the Inner Mongolia autonomous region.

Tubbat treats each saxaul - a nearly leafless tree which grows in sandy soil - like his child. He waters them and continues to plant more every spring.
