Create a 3D scene of a barren wasteland with dead trees, cracked earth, polluted streams, and a dark, stormy sky. The sky should be filled with heavy, dark clouds, and the streams should be filled with murky, polluted water. The dead trees should be scattered throughout the scene and should be twisted and gnarled. The earth should be cracked and dry, and there should be no sign of life anywhere. Your scene should be bleak and desolate, and should transport the viewer to a world of despair and hopelessness.
