Re: Solving desertification in China with rabbits
5:12 rabbits were the secret weapon to combat desertification. The rabbits can't digest grass seeds, so their manure contains seeds + phosphorous + nitrogen making a perfect nutrient for the grass.
5:45 willows were planted - their roots can stretch 300 feet deep to reach sources of water [A search suggests their roots can only extend about 1.6m deep.]
