Farmers in Nebraska, Colorado, Kansas , and the Texas panhandle produce about 1/6 of the world’s grain. The single greatest source of ground water the High Plains Aquifer provides the moisture for all that growth. However, a group of researchers has found that after more than 50 yrs of ground water pumping long segments of rivers are drying up and the collapse of large stream fishes. If pumping practices are not changed more rivers will be under pressure.
What is important to note that what is being seen here has implications for watersheds around the world. Irrigation accounts for 90% of the water use globally..local and regional aquifers are drying up.
Essentially , over time we are drying up the land…at some point a wall will be hit. Future generations may lose the ability to work the land , grow crops, water the animals, lose trees and grass and so on.
