The other day, we watched a presentation “Leather and meat without killing animals”. In the presentation, the presenter insisted that we slaughter animals to make meat and leather, and it is not good because it will bring risks to us and our planet. Then, he suggested a new way. That is biofabrication. This technique is that cells themselves can be used to grow biological products like tissues and organs. Already in medicine, biofabrication techniques have been used to grow sophisticated body parts, like ears, windpipes, skin, blood vessels and bone, that have been successfully implanted into patients. He told that we should begin by reimagining leather because it is so widely used. Growing leather is also technically simpler than growing other animal products like meat. It mainly uses one cell type, and it is largely two-dimensional. It is also less polarizing for consumers and regulators. In this sense, leather is a gateway material, a beginning for the mainstream biofabrication industry.
I agree with his opinion for 3 reasons.
Firstly, biofabrication need no sacrifice. When we make meat and leather, we slaughter animals. We make them by killing their lives. This situation is crazy. Indeed, we must eat meat to live a life, but we use leather exclusively to make themselves look dandy and smart. Then, when we make meat and lather by biofabrication, we use only a cell. Secondly, the number of population will increase, and we will have to slaughter more animals, but there is a limit of the number of animals. So we should use biofabrication.
Thirdly, if biofabricaton is spread, we can make much leather. Therefore, by the law of supply and demand, the price of leather will be lower. It is economic.
However, it will need many time for people to apply meat which is made by biofabricstion.
