Land health is the capacity for self-renewal in the soils, waters, plants, and animals that collectively comprise the land.
Aldo LeopoldAll conservation of wildness is self-defeating, for to cherish we must see and fondle, and when enough have seen and fondled, there is no wilderness left to cherish.
Aldo LeopoldThere are idle spots on every farm, and every highway is bordered by an idle strip as long as it is; keep cow, plow, and mower out of these idle spots, and the full native flora, plus dozens of interesting stowaways from foreign parts, could be part of the normal environment of every citizen.
