If everyone knows that falling leaves is synonymous with fall, who knows the necessary reasons? No, the adjective is not too strong. Because if the trees get rid of the leaves – after “killing” them, it should be mentioned along the way – it’s just … so they don’t die on their own!

Live and let them die

Imagine that when it starts to cool, the liquids that pass through the leaves can freeze. Then the trees, theoretically, have two options: maintain the temperature, risking to expend all their energy there, or let them die to retain only their strongest elements, i.e. the trunk, bark and branches. We better understand their “choice,” don’t we?
