The general struggle of living beings for existence is &hellip a struggle for negentropy that
becomes available in the transition of energy form the hot sun to the cold earth. To exploit this
transition as much as possible the plants spread out the immeasurable areas of their leaves and force
the solar energy &hellip to carry out chemical syntheses of which we have no idea in our laboratories.
