Mink's role in nature is important. Since mink is a carnivorous species, there are small mammals such as crayfish, snakes, turtles, small birds, mice, rabbits, insects, and crustaceans in the food chain. The most important of the practices that threaten the life of the mink is the cutting of the trees where the mink lives for furniture or energy production. Another threat is that their fur is made into clothes, as in Denmark, where 1 billion dollars of exports are made annually. However, the recent acceptance of the covid virus as a host to humans resulted in 17 million minks being buried in the mass grave in just the first week, and then the entire culling of them. Here it is not the resignation of a responsible prime minister. It is the threat that the mink, which forms part of the food chain, will suddenly increase the population of small birds, which play a key role in world food production. Of course, the purpose here is not to blame everyone unconsciously. However, instead of interfering with the chain in nature, the mink should be kept under quarantine by considering the antibody formed in the bodies of the mink as a treatment tool. Now the world should be prepared for unexpected adverse effects, such as the growing bird population with the disappearance of those 17 million minks. The species that need to be increased in the fight against Covid-19 are bats, the main source of the virus. Because bats may have carried a combination of SARS and MERS viruses from the same source in the past as a defense mechanism to adapt to nature with the depletion of water flies in the world with the restriction of water resources. The presence of any population in nature that is more than normal may further limit the use of a biosource present in nature. Every intervention in nature inevitably confronts humanity. As an alternative thought, it may be suggested that minks should not be considered as a commercial purpose in human life or should be restricted.
