Environment is one of the thing that the company should emphasize on. Most companies decrease their cost to have high profit by destroy environment, such as releasing chemical water to the canal without using a strainer before releasing water. Although a strainer is not much expensive, the company want to save their cost by cutting unnecessary things for the procedure, and the company do not care about effects which will come after from doing those things. Therefore, water in the canal is rotten, many living things die, and those dead bodies stink. Moreover, those rotten things also affect people’s health both physical and mental.
