by Henry David Thoreau.

O Cavalo de Ferro que tantas vezes Thoreau menciona. Foi ele que trouxe esta precariedade à sociedade actual. Tudo começou com o rasgar das montanhas e o transporte incessável de cegos e mercadorias para os mais capitalistas.
Thoreau mostra uma visão romântica e adaptada aos problemas do século XXI em que as linhas que guiam o pensamento das sociedades conduzem para a sobre-exploração dos recursos sem nunca olhar para consequências a longo prazo que afectarão as gerações futuras e o equilíbrio natural do nosso lar, a que chamamos Terra.

"White Pond and Walden are great crystals on the surface of the earth, Lakes of Light. If they were permanently congealed, and small enough to be clutched, they would, perchance, be carried off by slaves, like precious stones, to adorn the heads of emperors; but being liquid, and ample, and secured to us and our successors forever, we disregard them, and run after the diamond of Kohinoor. 

They are too pure to have a market value; they contain no muck. 

How much more beautiful than our lives, how much more transparent than our characters, are they!

We never learned meanness of them. 

How much fairer than the pool before the farmers door, in which his ducks swim!

Hither the clean wild ducks come.

Nature has no human inhabitant who appreciates her. 

The birds with their plumage and their notes are in harmony with the flowers, but what youth or maiden conspires with the wild luxuriant beauty of Nature? 

She flourishes most alone, far from the towns where they reside. 

Talk of heaven! ye disgrace earth."
