Mother pays tribute to late son by greening the Inner Mongolia deserts

For the past decade, Yi Jiefang has been on a crusade to honour the wish of her deceased son - to plant the deserts of Inner Mongolia with trees. Now, with more than 1.1 million trees in the ground, the 65-year-old who has poured most of her savings into the cause says she must carry on, not just for the sake of her son but to raise awareness of the role of trees in protecting the environment.
