Why some may laugh and snicker at this proposal, the ones behind this a very serious. The over arching vision is called "Wildlands". These folks want to take the Great Plains and eliminate human occupancy restoring the area to it's natural state so the 'buffalo' can run free again.
Here's a link:

"hundreds of thousands of hectares..."
A hectare is 10,000 square meters or about 2.47 acres. IOW, they're talking about 2,470,000 acres (plus) depending upon how many hundreds of thousands involved.
Get serious about these guys. They're into Deep Ecology which is based upon the theory that a man is no more valuable than a flea. When I said they are out to remove man from the great plains, I meant that. They would like to remove all traces of man including towns, cities, farms, roads, etc. from the great plains, all for the buffalo, etc.
Thanks for the link. Demonstrating again, that all you want to find about can pretty much be found here.
