50. Learning From Nature
A Radio Talk by Charles F. Kettering
This is Palm Sunday, and if nature follows her
usual custom, it
won't be long before most of the Northern Hemisphere will be green
again. I can think of no better time to reexamine some of the things we
have inherited from nature - especially the miracle of plant life and
the green leaf.
In a short time, thousands of us will be digging in the earth and
planting seeds - Victory gardens, we will call them. The farmer will be
doing the same thing but on a much larger scale. As an experiment, we
might try planting in a single row all the different kinds of seeds.
And if we are patient, out of that row we can eventually get vegetables
and seeds of all kinds, and flowers of all colors from the same earth,
receiving the same sunshine! Thousands of different materials - a
chemical factory supreme, without even a test tube or Bunsen burner!
How this is done remains one of the important
unsolved problems.
Man, with all of his knowledge, has not been able to tell us much of
the why or how of the green leaf. Yet we know this is the fundamental
link between life on earth and the inexhaustible energy of the sun. We
depend on the leaf for our food and clothing - our very existence.
