As I was driving through the bowels of Jersey yesterday i saw a few sale signs on some McMansions that stand in what was a vast cornfield. I thought maybe we should just plow them down or move them and return the land to farming...
Not in our lifetimes or for many generations...but someday with the soaring population of this earth, such a thing probably will happen.
Eminant domain laws today are used to build highways to get out to these McMansions. Someday that land will be needed again for food. It actually might happen quicker than we think. The world's grain supply has been at a deficit compared with demand for 7 out of the past 8 years.
