Famous quotes containing the words land and/or degradation:
“That land is like an Eagle, whose young gaze
Feeds on the noontide beam, whose golden plume
Floats moveless on the storm, and in the blaze
Of sunrise gleams when Earth is wrapped in gloom;
An epitaph of glory for the tomb
Of murdered Europe may thy fame be made,
Great People! as the sands shalt thou become;
Thy growth is swift as morn, when night must fade;
The multitudinous Earth shall sleep beneath thy shade.”
—Percy Bysshe Shelley (1792–1822)
“Such poverty as we have today in all our great cities degrades the poor, and infects with its degradation the whole neighborhood in which they live. And whatever can degrade a neighborhood can degrade a country and a continent and finally the whole civilized world, which is only a large neighborhood.”
—George Bernard Shaw (1856–1950)
