1.Bending the curve of terrestrial biodiversity needs an integrated strategy
The number of animals on earth is decreasing and biodiversity is being destroyed. This is a global problem that will take a generation to solve, but hard work must begin today.Biodiversity is the sum of the ecological complexes formed by organisms and the environment, as well as the various ecological processes related thereto, including millions of animals, plants, microorganisms and the genes they possess, as well as their formation with their living environment The complex ecosystem is the basic feature of life system.

The best way is ti find a good balance between people and the nature.And the life system is a hierarchical system, including multiple levels or levels: genes, cells, tissues, organs, populations, species, communities, ecosystems, and landscapes. Each level has rich changes, that is, there is diversity.

However, the main ones that are important in theory and practice and have been studied are gene diversity (or genetic diversity), species diversity, ecosystem diversity and landscape diversity. Nowadays, people often regard biodiversity as the living entity itself, not just as one of the important features of the living system.

The diversity of human culture can also be considered part of biodiversity. Just like genetic diversity and species diversity, some characteristics of human culture (such as nomadic life and mobile farming) show people's strategies for survival in special environments. At the same time, like other aspects of biodiversity, cultural diversity helps people adapt to changing external conditions. Cultural diversity is manifested in the diversity of language, religious beliefs, land management practices, art, music, social structure, crop selection, diet, and countless other human social characteristics.

Biodiversity is the material basis for human survival, and its value can be understood from the following two aspects. First, direct value. From the wild and domesticated components of biodiversity, humans have obtained all the food, many medicines and industrial raw materials they need. At the same time, it also plays an important role in entertainment and tourism; second, indirect value. Indirect value is mainly related to the function of the ecosystem. Usually it is not reflected in the national accounting system, but if calculated, its value greatly exceeds its direct value of consumption and production. The indirect value of biodiversity is mainly manifested in seven aspects: fixing solar energy, regulating hydrological processes, preventing soil erosion, regulating climate, absorbing and decomposing pollutants, storing nutrient elements, promoting nutrient cycling and maintaining evolutionary processes. Over time, the greatest value of biodiversity may lie in providing humans with opportunities to adapt to local and global changes. The unknown potential of biodiversity presents immeasurable bright prospects for human survival and development.
6.A decade ago, the world agreed to 20 biodiversity targets. It did not meet any of them.
In recent years, the increase in species extinctions, the reduction of genetic diversity, and the large-scale destruction of ecosystems, especially tropical forests, have aroused great attention from the international community on biodiversity issues. The direct causes of biodiversity loss are mainly habitat loss and fragmentation, invasion of alien species, over-exploitation of biological resources, environmental pollution, global climate change, and industrialized agriculture and forestry. But these are not the root of the problem. The root cause is the rapid increase in population and the high rate of consumption of natural resources, the ever-narrowing trade spectrum of agriculture, forestry, and fishery, economic systems and policies that fail to assess the value of the environment and its resources, Unbalanced distribution of benefits from resource utilization and protection, insufficient knowledge and its application, and unreasonable laws and systems. All in all, human activities are the root cause of the unprecedented loss of biodiversity.

The significance of biodiversity is mainly reflected in the value of biodiversity. For humans, biodiversity has direct use value, indirect use value and potential use value. Direct value organisms provide humans with food, fiber, building and furniture materials, medicines and other industrial raw materials. In terms of medicine alone, 80% of the population of developing countries rely on traditional medicines provided by plants or animals to ensure basic health. 40% of medicines used in Western medicine contain substances originally found in wild plants. For example, according to recent surveys, more than 10,000 kinds of plant medicinal materials are used in Chinese medicine.

Biodiversity also has aesthetic value, which can cultivate people's sentiments and beautify people's lives. If there are no colorful plants and animals with different looks in the great world, people's travel and leisure will be dull. It is the combination of the majestic and beautiful mountains and rivers with the colorful flowers, birds, fish and insects that constitute a pleasing and lingering beauty.In addition, biodiversity can also inspire people's literary and artistic creation. Indirect use value Indirect use value refers to the important ecological function of biodiversity. No matter what kind of ecosystem, wildlife is an indispensable component.
9.More than 150 countries made a plan to preserve biodiversity a decade ago. A new report says they mostly failed.
In the ecosystem, wildlife has an interdependent and mutually restrictive relationship, and they jointly maintain the structure and function of the ecosystem. Once the wildlife is reduced, the stability of the ecosystem will be destroyed, and the human living environment will also be affected. There are many types of wild life with potential use value, and human beings have done relatively sufficient research on them, but only a few. The use value of a large number of wild life is still unclear. But it is certain that these wild creatures have huge potential use value. Once a wild life disappears from the earth, it cannot be regenerated, and its various potential use values no longer exist. Therefore, wildlife whose potential use value is not yet known should also be cherished and protected.

Ecosystem is a natural complex composed of various organisms and their surrounding environment. All species are part of the ecosystem. In the ecosystem, not only do species depend on and restrict each other, but organisms also interact with various environmental factors around them. From a structural point of view, the ecosystem is mainly composed of producers, consumers, and decomposers. The function of the ecosystem is to circulate the various chemical elements on the earth and maintain the normal flow of energy between the components. The diversity of ecosystems mainly refers to the diversity of the composition and function of the ecosystem on the earth, as well as the diversity of various ecological processes, including the diversity of habitats, biological communities and ecological processes. Among them, the diversity of habitats is the basis for the formation of ecosystem diversity, and the diversity of biological communities can reflect the diversity of ecosystem types.
