All kinds of creatures are the precious wealth of all mankind. Biodiversity provides abundant necessities such as food, medicine and fuel and a large number of industrial raw materials for human survival and development. Biodiversity maintains the ecological balance of nature and provides good environmental conditions for human survival. Biodiversity is an indispensable part of ecosystem, and people rely on ecosystem to purify air, water and enrich soil. Scientific experiments have proved that the more species in an ecosystem, the greater its creativity. All living things in nature are interdependent and mutually restrictive. The extinction of every species indicates that many species are about to die out.
Biodiversity also has important scientific research value. Each species has a unique function. For example, by crossing wild rice with rice in farmland, new rice varieties can increase rice yield in a large area. In some plants that humans have not studied, there may be ingredients that fight against human diseases. If these wild animals and plants disappear, it will be a great loss to mankind.
China is one of the countries with the richest biodiversity on earth. Vast territory, vast sea area, complex and diverse natural conditions, and ancient geological history have bred extremely rich species of plants, animals and microorganisms, with a variety of ecological combinations. It is one of the 65,438+02 countries with rich diversity in the world. There are not only many types of wild species and ecosystems, but also many varieties of cultivated plants and livestock and their wild relatives. In addition, there are many endemic genera and species in China, with ancient flora and fauna and rich rare species.
Biodiversity includes the diversity of biological species, genes and ecosystems. The significance of biodiversity is mainly reflected in the value of biodiversity. For human beings, the direct utilization value of biodiversity is that organisms provide human beings with industrial raw materials such as food, fiber, buildings and furniture, medicines and so on. Indirect use value means that biodiversity has important ecological functions. No matter what kind of ecosystem, wild animals are an indispensable part. In the ecosystem, wild animals depend on and restrict each other, and * * * maintains the structure and function of the ecosystem. Once the wildlife is reduced, the stability of the ecosystem will be destroyed and the living environment of human beings will be affected. The potential utilization value lies in that there are many kinds of wild animals, only a few of which have been fully studied by human beings, and the value of a large number of wild animals is still unclear. But what is certain is that these wild creatures have great potential utilization value. Once the wildlife disappears from the earth, it can't be regenerated, and its potential use value no longer exists.
At the same time, biodiversity also has aesthetic value. Colorful animals and plants with different expressions in the world can cooperate with famous mountains and rivers to form pleasing beauty, thus inspiring literary and artistic creation.
