There will be animals without pain

According to physicists' Web site, along with the continuous progress of genetic engineering, the researchers said, soon they will create an animal that does not feel pain in farms .

Although this method can make the animals living in the farms suffer less pain, but what makes people think is when not making animals have no sense of pain is one way Cruel or not, is a very controversial issue. In recent decades, people consume more and more foods of meat. Beginning in the 60s of the 20th century, the amount of meat consumed by humans has increased by 50%, of which most meat products are produced from farms.

Animal welfare organizations require that animals be treated better in the farm, not to allow them to suffer unnecessary pain. For example, people cut off some of their wounds in school but don't use numbing medicine.

If it is not possible to persuade farms to raise animals in a humane environment, then it is time to provide animals with adequate natural prevention mechanisms.

This may not be an ideal measure, but Adam Shriver, a philosopher from the University of Washington's St. Louis branch, said: ' If we cannot remove the breeding methods of factories, then We should limit their pain to a minimum. '

In recent years, scientists have made tremendous progress in the field of molecular research and pain on the basis of genes. In a recent study, mice that lacked the gene Nav 1.7 had a lower sensitivity than normal mice in hot and high-pressure environments . Animals in farms that lack this gene will experience less pain.

In another study, the scientists raised mice that in the ACC class before the brain did not have the enzyme and the default gene. This change makes mice still feel pain, but they do not think that pain is not necessarily an unpleasant feeling. This makes them still have a physiological sense of being able to avoid other animals that cause them to be injured, those individuals who are born without the pain often experience such a situation.

In addition, there is another method to create animals without pain, one of which is in vitro meat production . Although the technology is still incomplete, the method of raising animal muscle cells can be used to produce fried chicken and grilled fish. However, the price to produce animal cells in the laboratory is still too expensive, because to feed them must use extremely expensive materials. This project must be scaled up, to create economic benefits. In addition to reducing the pain of animals, this method can also eliminate other negative effects in farms, including a large amount of waste and CO2 emitted by animals.
