Calvin and Hobbes by Bill Watterson for November 27, 1995
Calvin: People keep talking about opening more wilderness for development. We seem to understand the value of oil, timber, minerals, and housing, but not the value of unspoiled beauty, wildlife, solitude, and spiritual renewal. Hobbes: We need to start putting prices on the priceless. Calvin: Yeah, if our woods are worth a zillion bagillion, think what Alaska is worth.
