An international Popular and in-demand soft drink company has a signature soft drink that it sells all over the world. In Bangladesh, the soft drink variants comply with all Bangladesh Food and Health regulations but circulates a less healthy version than the drink sold in the European market where the law is stricter. This international soft drink company offers huge job opportunity to the people of Bangladesh. The country's soft drink business also flourished due to its popular brand and its big demand for the market. However, the company uses up huge amount of water supply, especially during the summer months. This becomes a problem, because during these months a large amount of water is required for our irrigation, household use and also to produce soft drinks. The soft drink company is obeying all Bangladeshi law, but it sells an inferior, less healthy product in a developing country.
