The whole fauna of human fantasies, their marine vegetation, drifts and luxuriates in the dimly lit zones of human activity, as though plaiting thick tresses of darkness. Here, too, appear the lighthouses of the mind, with their outward resemblance to less pure symbols. The gateway to mystery swings open at the touch of human weakness and we have entered the realms of darkness. One false step, one slurred syllable together reveal a man's thoughts.
— Louis Aragon

When one subtracts from life infancy (which is vegetation), sleep, eating and swilling, buttoning and unbuttoning -- how much remains of downright existence? The summer of a dormouse.
Lord Byron vegetation quote

Approximately 80 % of our air pollution stems from hydrocarbons released by vegetation, so let's not go overboard in setting and enforcing tough emission standards from man-made sources.
— Ronald Reagan

Changes are not only possible and predictable, but to deny them is to be an accomplice to one's own unnecessary vegetation.
— Gail Sheehy

No part of the world can be truly understood without a knowledge of its garment of vegetation, for this determines not only the nature of the animal inhabitants but also the occupations of the majority of human beings.
