“Business is a commercial activity engaged in as means of livelihood or profit, or an entry which engaged in such activities.” By 
definition it is seemed that seeking profit is the essence of business.
Nowadays, people pay attention to making optimizing decisions environmental-friendly because they realize the resources are limited, that means we may run out of resources one day. However, not every executive is so considerate since being “green” requires more in their standards of their production and management.
Wal-Mart Brazil thinks so green, it announced significant goals to leave off companies that employ slave labor, soybeans sourced from illegally deforested areas and beef sourced from any newly cleared Amazonian land. As we know, Wal-Mart is an international corporation that “runs chains of large discount department stores and warehouse stores”. The implement of the decision would affect a serious of production line especially the suppliers of raw materials. Wal-Mart takes the Corporation Social Responsibility (CSR) and really means it, unlike some companies that use it as a promotion, which cater to people’s appeal to environmental-friendly brands. If the ethics standard could be set by entrepreneurs and of course, regulated by a third organization, the marketplace would be more sustainable.
