Human beings are an integral part of nature. In the past few hundred years, the irrational and rapid development of human society has made human activities a dominant negative factor affecting the stability of the natural environment in all circles of the earth.

The degradation or extinction of forest and grassland vegetation, the decline of biodiversity, the aggravation of soil erosion and pollution, the prominent greenhouse effect of the atmosphere and the destruction of the ozone layer have all sounded the alarm for mankind. Humans must be kind to nature and have some control over their own development and activities.

Nowadays, more and more children are growing up in "greenhouses", and there are fewer and fewer opportunities to be close to nature. Unconsciously, children are suffering from a "disease": nature deficiency disorder. It's not a medical diagnosis, it's just a phenomenon of humanity's gradual alienation from nature.

It refers to the fact that children have less and less time for outdoor activities, resulting in some physical and psychological problems of children: short-tempered, anxious, sickly, unable to withstand setbacks, inattention, lack of creativity, etc.

It refers to the fact that children have less and less time for outdoor activities, resulting in some physical and psychological problems for children: short-tempered, anxious, sickly, unable to withstand setbacks, inattention, lack of creativity, etc. . Let children go into nature, get close to nature, not just play, but the most important thing is to explore and learn in nature.

Children's obsession with nature will be transformed into caring about the details in nature, becoming optimistic, sunny, enthusiastic, and infinitely creative and imaginative; let children get close to nature, explore freely and independently in nature, Discover, experience, and share. Playing in learning and learning in play has greatly improved children's physical fitness, language, science, social communication skills, cooperation skills, adaptability, patience, and other aspects.

We must cherish the existing natural resources. In the context of the rapid development of modern industrialization, people were once in the comfort zone of consumption and hedonism. They only knew how to consume wildly, but they forgot that resources are limited. To achieve harmonious coexistence between man and nature, we must understand that natural resources are not unlimited.

We need to be brave and take responsibility for the balance of nature. After hundreds of millions of years of evolution, the natural ecosystem has maintained a natural balance while developing continuously. In this system, all life forms continue to develop in their respective positions.

Harmony and order are the prerequisites for development. Once some ecology is destroyed and this harmony is broken, it will directly affect the production and life of human beings. Therefore, we must assume the responsibility of natural balance and contribute to the harmonious development of man and nature.
