I think big companies have a positive effect on society because there are clear advantages in terms of products and the environment. To begin with, big companies generate good products. And, big companies can expand their companies all over the world because they have enough money to fund. Expanding their own companies leads to providing good products to a lot of people. Second, big companies can start eco-friendly projects. I think that it is very important to protect the environment. Considering the environment may prevent environmental issues such as air pollution and carbon dioxide problem from worsening. Therefore, I agree that big companies have a good effect on society because they can produce good products widely and carry out environmentally friendly businesses.
