The road to conservation is paved with good intentions that often prove futile, or even dangerous, due to a lack of understanding of either land or economic land use.

For one species to mourn the death of another is a new thing under the sun.

Wilderness is a resource which can shrink but not grow.

It is in midwinter that I sometimes glean from my pines... a curious transfusion of courage.

Prudence never kindled a fire in the human mind; I have no hope for conservation born of fear.

All 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.

The oldest task in human history: to live on a piece of land without spoiling it.
