With the deterioration of the ecological environment, ecological problems are getting more and more attention from the world. Jack London in Burning Daylight tries to show that in the process of the development of human civilization, human desires are expanding to the point of causing damage to the ecological environment. Jack London criticizes the greedy desires of human beings. Jack London advocates that by reducing human desires, returning to nature, bringing humans and nature closer together, eliminating anthropocentrism, and establishing ecological holism, in order to realize harmony between humans and nature. Jack London takes us to re-understand nature and reflect on the relationship between man and nature, only to deepen the understanding of nature, can realize the harmony between man and nature.
