· Say Oklahoma is considered mostly Plains, verging on Desert.

· Further, say that it's ethically right for people to live there in large
numbers, in that part of the continent.

· Lastly, say that Oklahoma, the USA, and the world, have enough food that
those farms on good soil are not quite-clearly-needed.

· Given those, I would agree with Diane that the small number of farms "had
to be" sacrificed to make way for the greater good, i.e. to "provide a good
water supply and recreation."


· But what if those conditions apply to a lesser degree, or don't apply at
all?

· Where (in what circumstances) are the conditions _not_ right for the
replacement of (i) plains grassland by farms, or later (ii) farms by a city
lake?

· There's a gradual change, but I think it's easy to imagine a river valley
in northern Canada where there is _insufficient_ justification for the
human development of building a lake and a city. (For one thing, the
transport, heating and other energy costs are too great when one includes
the environmental costs.)

· So once again, _where_ along this multi-dimensional continuum do you draw
the line and say "people; stop! it's not worth it!"? Or even "This is bad!"
