Sustainable farming methods that eschew agrichemicals. Former consumer co-op worker Kawasaki Hiroto is promoting these techniques in a small village on the northern reaches of China's Yellow River. At 66 he visited over a hundred Chinese farms to promote the use of compost and cyclical farming methods, but to no avail. He was at his wits' end when he met Li Wei, a farm owner in Henan province who'd struggled with organic farming. Together they rebuilt his farm with sustainable techniques, sharing their experiences through social media and training courses.
