Nope.

You're another one that doesn't have clue what you're talking about.
My property, once developed 120 years ago, is now leaving the juvenile stage and heading for mature over the next 50-75 years.
What that means is that the poplars are dying and the oaks and maples in the understory are about to take over. The evidence of civilization remaining is chunks of concrete and railroad track scattered here and there. About 90% has been buried by nature's floods, storms, snow and sun.

"The problem with your argument is that FARMS are being converted to urban plots. Not every plot of land can be planted because of terrain or just poor soil.
The country has a limit amount of GOOD farmland and it it the flat well drained acres that developers love most cause it is easier to cram lots of crappy houses upon.
And once good farmland is put under asphalt it is gone forever."
