"One would like to see mankind spend the balance of the century in a total effort to clean up and groom the surface of the globe — wipe out the jungles, turn deserts and swamps into arable land, terrace barren mountains, regulate rivers, eradicate all pests, control the weather, and make the whole land mass a fit habitation for Man. The globe should be our and not nature's home, and we no longer nature's guests."
