The Yangtze River Daily Da Wuhan Client News (Reporter Yang Xiaoyu, a trainee Zhang Cong) Does it mean that eating fish should be controlled? Why is there a rare drizzle in the city? How should flood disasters deal with? In the future, what is the state of human and natural ideals? On June 21, the academician planned by Academician Gui Jianfang's Natural Science Popularization Studio in Natural Science Popularization Studio, Academician Gui Jianfang, Academician Chen Xiaoping, and 7 expert representatives around "from ecological health to personal health, harmonious symbiosis such as man and nature, and symbiosis. "This theme, combined with its own scientific research direction and personal experience, expresses their own opinions and answers, and open up their brains to imagine the future.

The most suitable food for the future is "blue food"?

Gui Jianfang, an academician of the Chinese Academy of Sciences, academicians of the Academy of Sciences of the Development National Sciences, and fish genetic breeding scholars, first started the topic. , Make the fish on the table of the people, bigger, more meat, and more beautiful. Gui Jianfang said that in the daily diet of Chinese residents, 30%of animal proteins are derived from aquatic creatures. The well -known scientific magazine "Nature" ("Nature") has proposed "blue food" in the cover article -the food obtained from the water may increase in the future. The harmonious development of man and nature, protection and utilization is not a contradiction, but to be used under the premise of protection. "It is inevitable that people's obtaining resources from nature requires us to better understand nature and more scientifically." Gui Jianfang explained, "As the aquaculture continues to improve, we can consume less resources. Get more aquatic foods. People do not need to eat fish, and they can also be coexisting harmoniously with nature. And with the continuous development of scientific research, people eating fish will be more convenient, safe, and delicious. "

Chen Xiaoping, an academician of the Chinese Academy of Sciences and an expert in liver and gallbladder and pancreas, discussed the inseparableness of human health and natural health. He introduced that the length of human life is only 30%depending on genetic genes, and the other 70%are related to the natural factors of the outside world. With the development of science and technology and the improvement of medical care, the life expectancy of human beings in recent years has increased significantly. "How old can humans live at most?" Chen Xiaoping said with a smile on the problem raised by college students at the scene: "Protect the natural environment, human beings may live until the age of 120 or even 150 years old." Some audiences asked if they really have healing function. Academician Chen answered that the concept of great health includes natural therapy, because man and nature are originally a whole. In contact with small animals in the natural environment, it is helpful for health. The levels will be different, but if you do n’t bother to get away, you still need to treat health issues scientifically, and scientifically use modern medical methods. Yang Xiaojing is an associate professor of China University of Geosciences (Wuhan). She also agrees with natural health on human health. At the same time, she should pay special attention to the scale of contact with wild animals because of the abnormal contact of human and wild animals -due to the original inhabitation, due to the original inhabitation The damage of the ground environment leads to the migration of animals. Wild animals are used as pets, or spelling, etc., may cause the spread of epidemic diseases.

"I remember in the countryside when I was a kid, I often drizzled, and it fell on my body, and my clothes would not be wet. Now in the city, there are few drizzle, and the particles of raindrops are mostly large." The China Meteorological Bureau. Wan Rong, a researcher and deputy director of the Wuhan Rainstorm Research Institute, started with the phenomenon observed and explained that this is because the urban environmental pollution increases the dust in the air, so water vapor condenses into a large water droplet. Wan Rong also mentioned that in recent years, extreme hydrological incidents -the probability of flooding has risen, which is closely related to human activities, so as to call on everyone to pay attention to the harmony with water. Xu Dong, a member of the Water Resources Commissioner of the Water Conservancy Mission of the Yangtze River and Water Conservancy, Xu Dong, deputy director of the Wuhan Eco -Environmental Technology Center, and the project researcher of the Institute of Aquatic Biological Research Institute of the Chinese Academy of Sciences, also pays great attention to the harmony of human water. Chen Jin said that the biggest natural disaster in Wuhan rivers and lakes is floods. Human water is harmonious, not to eliminate floods, but to dredge the "four water harmony" of water safety, water resources, water environment, and water ecology. In Xu Dong's view, the Yangtze River Protection Law and the recently implemented "Wetland Protection Law" can help improve water quality and protect aquatic biological resources.

When answering how humans and nature are most ideal, experts and scholars open their brains. Gu Yansheng, a professor at the School of Environment of the Chinese University of Geosciences (Wuhan), said that the ideal state of human and nature is that ecological health, rich biodiversity, achieve zero emissions of pollution, economically efficient, social fairness, and live in peace.
