Insect pesticides affect bird ecology instrument people talking about ecological protection

although we have always emphasized that the wrong use of pesticides will have adverse effects on the environment, and various countries have strict and scientific norms for the use of pesticides, its impact on the ecology may be worse than we think

recently, a paper published in the journal Nature sustainability mentioned that with the increase of the use of neonicotine pesticides in the mainland of the United States, bird diversity has decreased significantly. Coincidentally, relevant reports show that due to various factors, the bird population in the United States has decreased by 29% compared with that since 1970, and the use of pesticides is one of these factors that cannot be ignored

what's worse is that the use of pesticides has been directly related to the yield of grain in agricultural production, and pesticides are one of the key factors that directly affect whether agricultural production will suffer from pests. Obviously, including pesticides, the use of pesticides has had an obvious contradiction with regional ecology, and bird ecology is just one of them

maybe many people will have questions, why not prohibit the use of pesticides that harm birds? In fact, the key to the problem is that some hazards are potential hazards discovered later. In fact, at present, most pesticides, including pesticides, need to be strictly checked by scientific instruments to determine the composition before they can be put on the market for use. Among them, many pesticides are based on the stability of product quality and biological tolerance. Like the neonicotinoid insecticides mentioned above, one of the characteristics of this kind of insecticides is that it is highly toxic to insects but low toxic to other animals

however, low toxicity is not non-toxic. On the one hand, the ecosystem is based on a complex ecological chain, and any subtle toxin may add up in the process of ecological chain transmission, and may have a huge impact in a certain link, and this impact is often not really noticed until it actually occurs

is there a way to deal with this situation now? Naturally, there are some, but there are complex causes and consequences behind, so that the actual work of ecological protection is more complex than expected

let's start with the contradiction. The output of agricultural production not only affects human grain reserves, but also affects the situation of animal husbandry. Many domestic livestock rations are also obtained through agricultural production. If the output of animal husbandry decreases due to the reduction of agricultural production, it is likely to have a chain reaction like dominoes, affecting the stable operation of the entire food sector

on the other hand, the premise of reducing pesticides or, generally speaking, reducing the use of pesticides is to find more appropriate alternative methods, and the investment is self-evident. Although at present, there are many feasible green countries whose finance should increase financial support for scientific and technological research and development of strategic resources that have a bearing on the fate of the country, such as genetic programming, which artificially writes some genes that are not easy to be damaged by insects in crops, so as to reduce pests from the biological level, there is still a long way to go to realize its application

however, from another perspective, thanks to the technological development of protein water tablet detection and accounting level detection in recent years, the continuous innovation of PCR instruments and other related instruments, accelerating the cultivation and development of new generation information technology, high-end equipment, modern ocean and new energy vehicles and other strategic emerging industries, the development of genetically modified insect resistant crops is still very considerable, For example, transgenic insect resistant corn has long become one of the important projects in the field

objectively speaking, there is almost no perfect technology, but development is the process of making up for shortcomings. Maybe in the near future, pesticides will become history when loading. The development of technology and the progress of instruments will eventually pave the way for a better tomorrow
