I look at a high fence deer operation as a much cleaner, more environmentally friendly land use than many other legal farming operations that are perfectly legal such as dairy farms, hog farms, cattle operations, etc. Not near as many critters per square mile on a deer farm polluting the waterways and picking everything clean down to bare dirt. There aren't tons of manure to dispose of either, and they don't stink nearly as bad.

In fact it could be argued that a deer operation is more environmentally beneficial to general wildlife than clean grain farm field. After harvest a grain field has almost zero habitat value, while most deer operations at least leave some trees and cover that are beneficial to some small game year round.
