Famous quotes containing the words natural and/or habitat:
“If everybody is looking for it, then nobody is finding it. If we were cultured, we would not be conscious of lacking culture. We would regard it as something natural and would not make so much fuss about it. And if we knew the real value of this word we would be cultured enough not to give it so much importance.”
—Pablo Picasso (1881–1973)
“Nature is the mother and the habitat of man, even if sometimes a stepmother and an unfriendly home.”
—John Dewey (1859–1952)
