A professor said there is no god of love, since he sees warring everywhere from the molecular level to the gigantic level. For example, he said black walnut tree roots send out toxic chemicals to weed out almost all other plants near them.
I know no man can live without eating other plants/animals.
I think no plants/animals go extinct because of the toxic chemicals of black walnut trees. Every plant/animal benifit other plants/animals. Doesn't that show mutal help as a rule of life?
