Maybe drones can be used to bring water to arid areas where food can be planted to feed the hungry.

I heard about or read something somewhere that said once an arid region was brought back to life with forests and vegetation it improves the climate there making it possible to do farming.

Maybe they can be used to build a bridge to the village living on the side of a cliff badly in need of water and have no food either.

Maybe they should move off the side of a cliff nearer to the water and food supply. The knuckleheads.

Maybe they don't have knuckles and have to stay where they are....

Well if they don't have knuckles how did they get up the cliff?
