“If the Torah had not been given, we would still have learned modesty from the cat, industriousness from the ant…” and many important instructions-by-example from the plant kingdom. [TB Eruvin 100b] For example, fruit trees teach us that a “klipah precedes the fruit and serves to guard it” הקליפה קודמת להיות משמרת לפרי)).” [Ari, Likutei Torah, Bereshit and numerous other places]. The klipah’s tough (and often green) husk protects the immature fruit from predators, freezing weather, infestations and the like.
