On April 22, 2022, I closed the door and wept alone. One by one, one by one, shed tears for a person's death. It was a sad morning. His name is Jacques Behan. His works have deeply influenced me - let me understand two words: moderation and emotion. Before that, I had rarely seen movies, but because of the name of Jacques Behan, I walked into the cinema one day in 2004. At the moment of watching the migrating birds, I was almost stunned by the huge shock of the film. I have no idea how I got out of the cinema. Migratory birds is a natural documentary directed by Jacques Behan, which describes the difficult migration of various migratory birds for survival. From the cold Arctic to the hot desert, from the deep valley to the 10000 meter high altitude, migratory birds have shown amazing courage, courage, wisdom and emotion in the face of various dangers and human greed during their migration. The whole film has no dramatic plot and ups and downs of the characters' fate, but only the encounter, joy and misfortune of birds. The flight of birds is a miracle. The wings flicker in the wind, and we seem to be able to touch the particles of the wind. However, the clearer you see, the more desolate you feel. It is said that the narration and explanation of this 96 minute documentary should not exceed 500 words. Why did Jacques Behan make such a documentary? In his childhood, Jacques Behan was a naughty child. He likes to climb trees and dig out birds' eggs. "The faces of childhood, together with the deep feelings, are so precious to everyone. On the road of life in the future, the memories of childhood cannot be erased." One autumn evening, when Jacques Behan was watching a group of nameless migratory birds fluttering their wings over Paris, he suddenly wanted to fly. He said: "in the human dream, there is always a dream of freedom - a dream of flying like a bird." Jacques Behan said, "the only thing that matters to me is emotion." Yes, people will experience countless things in their life, but how many can we remember? However, the things that we pour our emotions into will always be remembered. For example, first love; For example, college entrance examination; For example, the first literary work published. Perhaps there is no complicated reason for Jacques Behan to shoot the migratory birds. It is just emotion. Therefore, I think of the issue of ecological literature creation - when we talk about such big words as "Earth", "human", "mission" and "responsibility", have we neglected some of the most essential things? Like literature, the important difference between ecological literature and official documents, news and other styles is that it has emotions. People have feelings of joy, anger, sorrow, joy, love, hate and hatred. Once people come into contact with foreign things, they will inevitably have some feelings. Emotion is the inner psychological activity of human beings. Emotions are complex and changeable. It flows and changes with people's positions, viewpoints and life experiences. In nature, what kind of emotion a writer has, what kind of emotion will flow in his works. It can be said that emotional stimulation is the motivation of ecological literature creation.
