In order to dry clothes, someone tied wire to two trees not far apart. Over time, the iron wire formed an iron hoop and was firmly pulled into the trunk, leaving a deep groove on the tree. Two years later, the hoop was deeply pulled into the tree. The poor tree seemed to be dying, but a miracle happened. The tree didn't strangle, but stood up firmly and swallowed the terrible iron hoop alive!
And all this happened to be seen by a desperate old man, and he summoned up the courage to live. The old man has cancer! He overcame his illness and survived. After living for several years, his last words when he died were: Thank you for that tree! ?
Nature refers to nature in a narrow sense. It is a material world different from human society. That is, the inorganic world and organic world of natural science research. Nature exists objectively; It is the foundation for the growth of human beings, the product of nature.
The relationship between nature and human society: nature is like butter on the side of bread, and human society is bread. Society refers to science and technology, humanities, greening, competition and commerce, which are all imaginary things, while nature is real things.
