The earth(ground) symbolizes the life, it regenerates thanks to the alternation "production / recycling" of organic matters. Earthworms are an essential link of this cycle. They are animals the most spread on the planet. Their action(share) in the reconstruction and the aeration of grounds is essential. They are also a gigantic reservoir of food for numerous animals. The mechanization of the work of the earth(ground) and the custom(usage) of massive fertilizer affect very seriously the population of earthworms, with negative effects on the environment. Consequence, the desert progresses!
