In order to provide the population with high-quality and natural food products, renewable fuel, which is one of the problems of biological science today, several effective works are being carried out in a number of countries. In particular, the development of biotechnology is gaining great importance for improving people's lives. A number of scientists are creating new varieties of plants that are important for human life, and several methods of their reproduction are being implemented. Microclonal propagation of plants in vitro is playing an important role as one of these methods. With the help of this method, it is possible to create a new plant throughout the year at the expense of the meristem cells of the plant. The participation of phytohormones among special substances in this method is important. These phytohormones, which are needed in very small quantities for the plant, but carry out very necessary processes, mainly include abscisic acid, brassinosteroids, ethylene, jasmonates, salicylic acid, strigolactones, auxin, cytokinin, gibberellin and several hormones. They participate in the formation of plant organs such as roots, stems, and leaves.

This article shows that today's actual problem is material damage to the environment and nature, and the role of humans in it. Also, the reasons why environmental protection is a global problem today and its prevention are given.
