Sustainability could be defined in many ways. It could be defined as the process of sustaining a process or developing new technologies to reduce environmental pollution. It also means a measurement of the degree of pollution of the environment by other factors. I must admit that sustainability is a great idea related to many fields such as health, economy, nutrition, social, etc. However, I still remember the first day of the "Sustainable Business" course, Professor Laverty showed my class an example of a sustainable product with the idea of ​​“producing more with less waste”. This example narrows me down to an idea of ​​“sustainable business,” which is producing products and services efficiently and sustainably without causing harm to the environment. In this essay, I want to highlight the impact of business on the environment, the profitability of sustainable businesses, and the responsibility of business. Jeff Butcher and Rachel Hill highlighted the impact of business on the environment, stating: “The more a product is consumed or produced, the greater the externality that results” (Butcher, Jeff, & Hill, Rachel, 2006). Obviously, we can see that a manufactured product will bring benefits to the consumer, sellers and manufacturers. Meanwhile, the one produced and consumed will cause negative externalities for the environment. There is a fact that we cannot deny: the more social life develops, the greater the externalities produced for society. Daily waste, industrial waste, carbon dioxide from factories are the most striking examples to describe negative externalities for the environment (Butcher, Jeff and Hill, Rachel, 2006). In “The Tragedy of the Commons,” Hardin showed us the causes of negative externalities. It has shown that people take up a... middle of paper......amount of water consumption and prevent environmental pollution from producing dying chemical waste in the environment. Even if these actions will not solve all environmental pollution, they reflect the attempt to adopt measures aimed at increasing positive externalities. In conclusion, I must say that there is a solid invisible relationship between the impacts of businesses on the environment, the profitability of sustainable businesses, and corporate responsibility. When one of these changes, it will affect the others as well. When a company adapts an efficient and sustainable system, it will reduce negative externalities and increase positive externalities for the environment. Once the company adapts an efficient business model, it will reduce costs and maximize profits. Obviously, the sustainable and efficient business model will make the social enterprise more responsible towards the environment.
