Buchholz bleibt (1990)

Captain Buchholz has been studying soil hardness, earth's gravitational pull, and the consistency of tree trunks and root systems for years. Since 1962, he has been weighing the earth and collecting samples. And he has noticed that the weight changes from year to year. The earth is becoming lighter and the soil looser. Stones that Buchholz throws to the ground take longer to land than they used to. Flying insects are no longer able to be held on the ground by the gravitational pull of the earth. He sets off and secures trees.
