Water is an obsession of farmers; they account for over 70% of human consumption of the stuff. However, they also focus on getting rid of water because drowning crops or compacting their farm land are serious issues. Enter drainage, a seemingly ideal solution for this pesky problem. However, there’s no pure positive in life, and with drainage the downsides are numerous; flooding, contamination of water with pesticides and other chemicals, and the transformation of important wetlands into farmland. Half of our wetlands have been transformed in this manner and they are crucial in the prevention of flooding as well as serving as the habitat for many species of fish and wildlife.
