The expansion of the E-commerce industry causes a lot of problems such as accelerating climate change. It is because people go shopping easily nowadays. They just go to online stores and make their orders. Companies will deliver those goods or products to their home directly. It is very convenient but it will increase the carbon dioxide emission from trucks. If we care about our world and our next generation, we have to pay attention to this expansion of E-commerce. Promotion and advertising are methods to improve the problem. For example, not to buy meaningless things or collect all things in one order. It can save the usage of trucks to deliver goods many times. On the other hand, we should speed up the usage of electric vehicles instead of traditional vehicles. It also helps decrease the emission of carbon dioxide. The expansion of the e-commerce industry is a trend in the world. We welcome it but we need to protect our world by decreasing the emission of carbon dioxide.
