Nowadays, as the development in food production, food and other essential products such as medicine or clothing made from animals are becoming less important to our life. Although there are several products that can replace the use of animals, I firmly believe that animals are still very necessary to humans, especially in food production and medicine.
On the one hand, the use of animals still plays a vital role in the world as well as bring about lots of useful products to our lives. In today’s world, some cattle such as chickens, cows provide a large amount of food for human daily diet. These types of foods made from animals can produce a high content of protein, which allows people to work more effectively and durably. While foods made from other resources such as vegetables or microbes may produce less energy than meat from animals. Moreover, animals are a large resource that can help humans to find out new medicine as well as vaccines. Once people cope with an adverse and deadly disease, animals can produce lots of specimens for experiments so that humans can rapidly research about the disease and look for the vaccine. For instance, when the deadly disease called Covid-19 appears, mice and monkeys are the most reliable specimens that help us to find lots of effective vaccines that are suitable for humans. Therefore, the use of animals in human lives is still very essential and helpful.
On the other hand, utilizing the use of animals can bring about lots of disadvantages if we cannot control it. Raising animals requires lots of vegetables, space and effort. The population on the Earth is increasing rapidly means that the amount of animals that are needed for humans also increases as well. Thus, humans find an alternative resource of food to decrease the pressure in producing food from animals. Otherwise, other products such as cloths, medicine can be replaced with plants. With modern advancement, some clothes are easily manufactured by plants, while clothes made from animal leathers require good ingredients as well as technical skills to create. For instance, people can manufacture clothes from cotton, which is much more eco-friendly and can be produced on a large scale. Therefore, some products made from animals can be replaced with other resources, particularly plants.
In conclusion, although the use of other resources can help people to produce some essential products, I believe that animals still play a vital role in human development. A wise approach, one that combines using animals and other resources to produce useful products for human lives, can maximize the overall development as well as minimize adverse consequences.
