Famous quotes containing the words single and/or species:
“We saw many straggling white pines, commonly unsound trees, which had therefore been skipped by the choppers; these were the largest trees we saw; and we occasionally passed a small wood in which this was the prevailing tree; but I did not notice nearly so many of these trees as I can see in a single walk in Concord.”
—Henry David Thoreau (18171862)
“Prostitution is the most hideous of the afflictions produced by the unequal distribution of the worlds goods; this infamy stigmatizes the human species and bears witness against the social organization far more than does crime.”
—Flora Tristan (18031844)
