A positive effect of irrigation is that it enables more food to be grown, thus feeding more people, and reducing the possibility of starvation. A negative effect is that irrigation may diminish the water available in a lake or other waterway, causing the lake to dry up, such as has happened to the Aral Sea in southern Russia. So much water was diverted by Soviet planners, to grow cotton, that the lake has virtually disappeared, causing a huge amount of ecological damage to the area.
