Many corporations are striving toward "net positive impact" of their activities. One such example is that of beverage manufacturers who have been encouraging practices that reduce water use and enhance the water table. Such practices include encouraging dryland rice farming, which uses much less water than traditional rice farming, and rainwater harvesting. Companies take credit for the water saved by these practices and, if this amount is larger than the water they withdraw from the watershed, they are said to achieve a positive water balance. From the point of view of corporate strategy, do you think it makes sense for a company to strive toward net positive impact? Discuss some advantages and disadvantages to the company from pursuing such activities.
