However, in terms of economic and social development, forbidding consumption of animal products altogether is not necessarily sound advice. Some species may become overpopulated without control, which can interfere with people's daily lives. Take kangaroos in Australia for example. In the 1990s, the overpopulation of kangaroos had seriously reduced the crop yield and caused traffic problems until the government allowed some people to hunt kangaroos for their meat. As a matter of fact, appropriate consumption of non-endangered species as sources of food and clothing would not damage the ecosystem. On the contrary, it can help to promote healthy interaction between humans and the wildlife. For example, a reasonable amount of daily intake of animal products can strengthen our immune system, which can protect us against contagious diseases. In summary, even though I agree that the hunting of endangered species should be banned, I would argue that the benefits of using non-endangered animals as sources of food and clothing are still significant.
