On October 12, 2021, the Chairman of the Supreme Leader attended the Summit of the 15th Conference of the Parties to the Convention on Biological Diversity and delivered a keynote speech, profoundly explaining the great significance of protecting biodiversity, advocating "building a community of life on earth together", and showing the world the responsibility and determination of China as a big country to protect biodiversity and strengthen global environmental governance. Biodiversity is related to the well-being of the earth’s homeland and the sustainable development of mankind. General Secretary of the Supreme Leader’s important exposition on jointly building a community of life on earth has broken through the theoretical paradigm of traditional utilitarian economics research and brought revolutionary cognition of biodiversity economics.

　　Human beings are a part of the life community of the earth, and the relationship between human beings and nature has gone through the process from primitive civilization passively adapting to nature to agricultural civilization actively utilizing nature. In the era of industrial civilization, the western traditional industrialization road excessively seeks to accumulate and expand material wealth while ignoring the national ecological well-being, and unilaterally emphasizes the conquest of nature, which leads to the aggravation and deterioration of the ecological environment and the continuous decline of biodiversity. At the United Nations Conference on Environment and Development held in 1992, more than 100 countries, including China, signed the Convention on Biological Diversity, which started the practical process of protecting the earth’s biodiversity. The Convention is one of the international environmental conventions with the largest number of signatories in the world, with a total of 196 parties.

　　After the entry into force of the Convention on Biological Diversity, the Conference of the Parties will be held every two years, and the biodiversity protection targets for the next 10 years will be set every 10 years. After a long and difficult negotiation, the 10th meeting held in Japan in 2010 adopted the United Nations Biodiversity 2020 Target (referred to as "Aichi Target"), and for the first time in the world, it put forward 20 action targets over a 10-year period, which is a milestone. However, the evaluation of the "Aichi Goal" conducted by the United Nations in 2020 shows that the report card for implementing the goal is not satisfactory. At the global level, none of the 20 "Aichi Goals" has been fully realized, and only six have been partially realized.

　　Turning political consensus into economic action needs the support of economic theory. Some international explorations have been made in this regard. For example, in the field of biodiversity economics, in 2005, Ecosystem and Human Well-being: A Comprehensive Report on Biodiversity, one of the results of the Millennium Ecosystem Assessment project of the United Nations, analyzed the relationship between biodiversity, ecosystem services (referring to the benefits that human beings get from ecosystems) and human well-being, expounded the value of biodiversity, evaluated the impact of ecosystem degradation on human well-being, and provided the basis for protecting biodiversity. In order to further deepen the analysis of economic theories, methods and policies, in early 2019, the West formed a report "Biodiversity Economics: dasgupta Assessment", which explained the economic value of biodiversity, provided a comprehensive analysis framework on the basis of ecological and earth science research, discussed how to consider the most precious natural capital of human beings in economic research, and tried to endow biodiversity with utility attributes similar to traditional products and services, so as to protect it by market means.

　　These studies are of positive significance to the protection of biodiversity, but their theoretical basis is mostly the hypothesis of rational economic man based on utilitarianism, emphasizing the pursuit of the maximization of individual self-interest. Based on this assumption, its prescription is nothing more than internalizing the external cost of biodiversity protection through taxation, avoiding the "tragedy of the commons" of biodiversity protection through property rights transactions of natural resources, and accounting the capital value of biodiversity through "shadow price". These methods can promote eco-environmental protection in different degrees, but because the same market accounting method and uniform market discount rate are used to calculate the benefits of economic development and biodiversity protection, there are also problems such as amplifying the current economic benefits and reducing the biodiversity benefits with low market transaction value but lasting and huge future benefits. It is from this utilitarian-based theoretical paradigm that some politicians in the United States refuse to sacrifice their current interests and contribute to the common future interests of mankind in the global biodiversity protection. After signing the Convention on Biological Diversity in the 1990s, the ratification procedure has not been completed. Some parties to the Convention on Biological Diversity have not fully fulfilled their responsibilities to achieve the "Aichi Target", resulting in a global biodiversity protection level far below expectations.

　　China’s overall implementation of the "Aichi Target" is better than the global average, and it is one of the most effective countries in the world. In recent years, China has adopted a series of effective policies and measures to promote ecological protection and restoration, delineated and strictly adhered to the red line of ecological protection, and earnestly implemented the "Aichi Goal". Among the 20 goals, 3 have made progress beyond the requirements of the "Aichi Goal", 13 have made key progress, and 4 have achieved phased results. As a developing country with fragile ecological environment and a large population, China has been able to hand over such an excellent answer sheet in biodiversity protection, which shows the important guiding significance of the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era to the modernization of harmonious coexistence between man and nature. This also shows that the theoretical research of biodiversity economics based on utilitarianism has obviously lagged behind practice, and it is necessary to build a new theoretical paradigm to promote the innovative development of biodiversity economics.

　　General Secretary Supreme Leader’s important exposition on jointly building a community of life on earth provides scientific guidance for the innovative development of biodiversity economics. In the new era, to innovate and develop biodiversity economics and construct a new theoretical paradigm, we should be based on the harmonious coexistence between man and nature, uphold the concept of life community on earth, and realize the coexistence, common prosperity and sharing of members of life community, rather than maximizing the self and current interests of "rational economic man". We should deeply realize that biodiversity is both natural wealth and economic wealth; It is not only related to the development of contemporary people and time and place, but also to the sustainable development of mankind. When calculating the benefits of economic development and biodiversity protection, it is necessary to distinguish between material assets and biodiversity assets to ensure both economic vitality and natural sustainable development. In methodology, it emphasizes systematicness and relevance, and it is not appropriate to simply analyze the marginal benefit or cost efficiency of a single factor. In the system of the earth life community, animals, plants and microorganisms form a dynamic balance, and mountains, rivers, forests, fields, lakes, grass, sand and ice are interrelated and evolve in a coordinated way. It is necessary to carry out integrated protection and systematic management, so that a good ecological environment can become an inexhaustible source of sustainable development.

On July 6, the Emergency Management Bureau of Heze City, Shandong Province issued a briefing:

On the afternoon of July 5th, affected by the warm and humid airflow in the southwest of the upper trough and the edge of subtropical high, natural disasters of strong convective tornadoes suddenly occurred in Dongming County and Juancheng County of Heze City, causing 88 injuries, of which 5 died after being rescued. Preliminary verification showed that 2,820 houses were damaged, 60,900 mu of farmland was affected, and 48 power supply lines were damaged.

At present, medical experts are doing their best to treat the injured. All kinds of disaster relief and production and life restoration work are in progress, and roads, power supply, water use and communication have been basically restored.

How did tornadoes form?

Tornado is a kind of small-scale air vortex generated under strong unstable weather conditions. The central wind force can reach 100 ~ 200m/s, and the diameter of the lower part of tornado is generally between several meters and hundreds of meters, and the extremely large tornado can reach 1km. After the tornado is formed, it usually lasts for ten minutes to several hours, and the attack range is small, but the destructive power is great.

Where are tornadoes prone to occur in China?

In the case of meeting weather conditions, the plain area is relatively high in tornadoes. For China, the middle and lower reaches of the Yangtze River, the Pearl River Delta, the Northeast Plain and the North China Plain are all areas where tornadoes occur more frequently. The plain area is densely populated, so special attention should be paid to prevention and response.

Common occurrence time of tornadoes

Spring and summer

Most of them occur in thunderstorm weather in summer.

Especially in the afternoon to evening.

Tornadoes are highly destructive.

When encountering a tornado,

We should quickly find a safe haven.
