When industries along major rivers such as the Nile River or the Congo River dump their factory wastes into the water, all that pollution is carried downstream. Then, because there are few if any water purification systems, the people who live downstream get all that pollution in their drinking water. If the water isn't distributed properly, then the farmers who need to irrigate their crops won't get to get as much water to their crops. The crops will then die, causing people to starve. Hope this helps!

Well, The unequal distribution of the water may cause wars affecting the Middle East with "Water Wars."With the pollution, people get sick and die from Dehydration and/or the bugs and insects living in the water getting inside your body and growing inside of you to make you sick. Either way, It can hurt the Middle East in a BIGway and the pollution has already begun in Africa. Soon, it may spread.
