Even insects, grass and trees you must not hurt. Nothing will be left, Nothing in the air, nothing under the earth, nothing in the waters. All will be exterminated. Nature understands her business better than we do. Nature to be commanded must be obeyed.
Nature uses as little as possible of anything.
We cannot think too highly of our nature, nor too humbly of ourselves. Weed - a plant whose virtues have not yet been discovered. Spring - An experience in immortality. The only thing we have to fear on this planet is man. Government cannot close its eyes to the pollution of waters, to the erosion of soil, to the slashing of forests any more than it can close its eyes to the need for slum clearance and schools.
