In some parts of the world, there is a concern that supplies of clean fresh water are not sufficient. One response to this has been to develop technologies for desalination, or the removal of salt from seawater. After salt is removed, the seawater is suitable for people, livestock, and plants. The salt that is removed is returned to the sea. What action would be most important for policy makers to undertake before deciding whether to build desalination plants in a region?
A. investigate the effect of increased salt concentrations on coastal ecosystems
B. investigate the mineral-level differences between groundwater and desalinated water
C. investigate the effect of the possible increase in people and livestock in the region based on increased water supply
D. investigate the relative cost and effectiveness of different water transport systems to carry water from the desalination plant
