In many of the world’s regions, increasing pressure on water resources has resulted both from expanding development, changes in climate, and from pollution, so that the future supply in some of the more arid areas is a concern going forward.
both from expanding development, changes in climate, and from pollution, so that the future supply in some of the more arid areas is a concern going forward
both from expanding development or changes in climate, and pollution, so that future supplies in some of the more arid areas are a concern
from expanding development, changes in climate, and also from pollution, so that the future supply in some of the more arid areas is a matter of concern going forward
from expanding development, changes in climate, and pollution, so that future supplies in some of the more arid areas are a concern
from expansion of development, changes in climate, and from pollution, so that supplies in some of the more arid areas are a future concern
The preposition both creates confusion since it indicates two factors, when the sentence actually lists three. If expanding development and changes in climate are supposed to be grouped together—implausibly—as a single factor, they should be conjoined by and, not separated by commas.
