Patents can reflect and protect individual labor achievements, but at the same time, they will also make the contents public and let others know their own labor achievements, which will lead to plagiarism and a vicious circle. The development of technology is backward if it does not advance.
Benefits of biotechnology:
1. Use biotechnology to improve quality, increase crop yield and select fine varieties. Including disease resistance genes, high protein genes and nitrogen fixation genes of grain crops, tobacco, cash crops, vegetables, fruits, flowers, trees and grasses. There is also rapid propagation, shortening the breeding cycle and getting more products faster. By cultivating artificial seeds, needed seedlings can be selected, with low cost and high income. And the emergence of new species as we know them.
2. It is widely used in medicine, especially in the production of expensive drugs, vaccines, new diagnostic techniques and new treatment methods. Using genetic engineering and cell engineering to produce drugs.
Such as growth hormone, growth hormone releasing inhibin, insulin, interferon, etc. On the other hand, with the continuous development of cloning technology, once the technology is mature, it will bring earth-shaking changes to the medical and health field and greatly improve the health level of human beings. Moreover, the emergence of IVF has brought unprecedented changes to human beings and brought good news to families with related needs. In addition, for endangered species, cloning technology is also very helpful in protection and restoration.
3. Developing clean new energy is the development direction of energy industry construction in the future, giving full play to the productivity of modern biotechnology. Develop new fuel cells. Fuel cell uses gaseous fuel, which has high efficiency and little pollution, and is a promising way of energy utilization. Make full use of organic garbage or organic wastewater as raw materials to produce hydrogen energy.
It is said that Japanese researchers have developed a new type of "fermentation equipment" to recycle domestic garbage for hydrogen production, which is more conducive to improving the effectiveness of hydrogen production from domestic garbage. The researchers of Harbin Jianzhu University in China established the technology of producing hydrogen from organic wastewater by microbial fermentation with anaerobic activated sludge as raw material.
4. The application of environmental protection can be divided into two categories, one is pollution monitoring and the other is pollution control. Modern biotechnology has established a new and effective method for rapid and accurate monitoring and evaluation of the environment, mainly including the use of new indicator organisms, nucleic acid probes and biosensors. In addition, there are biological enzyme technology, gold-labeled immunoassay technology, FCR technology, bioluminescence detection technology, biochip technology and biosensor.
Among them, biochip technology and biosensor are the most widely used. In environmental protection, gene chips are also widely used. Modern biotechnology is not only applied to environmental monitoring, but also to environmental pollution control. Modern biological treatment uses pure cultured microbial strains to degrade pollutants.
Disadvantages of biotechnology:
1. Biotechnology may also lead to the degradation of production methods and human health. This situation may appear with the emergence of transgenic crops that need special treatment, especially herbicide-resistant transgenic crops. Farmers must buy seeds and herbicides from the same company, otherwise herbicides will not work.
The same problem may also occur in genetically modified crops that need artificial fertilizers, which will replace traditional crops that rely on organic fertilizers, which are common in developing countries and are also conducive to environmental protection. The application of biotechnology in food will also bring many difficulties to farmers in developing countries. Biotechnology will also bring trouble to human health. For the sake of prevention, genetically modified crop products must be screened by immune testing before they can be used.
2. Biotechnology may also cause environmental problems. People use biotechnology to produce crops with drought resistance, salt tolerance and insect resistance, which also leads to serious damage to biodiversity and even extinction of some species. This result is due to the fact that biotechnology has promoted the expansion of crops to areas where it is not suitable.
Biotechnology has also accelerated soil erosion and desertification. The expansion of agriculture, especially cultivated agriculture, will increase the use of herbicides, pesticides and artificial fertilizers, and the continuous investment of energy in agriculture will promote global warming.
