Please discuss things observed in nature that teach us lessons.

For example:

Sunflowers, what can we learn from them? They always face the sun. They are tall with some of the largest flowers. They grow best in groups, because if growing singly or in low density populations, a little wind and rain will knock them over where they then dwell in the lower things of the earth, instead of supporting each other against the wind to grow straight op toward heaven. How can we expect to stay upright and heavenward, reaching great heights when we are so few and far between?
