The slogan at the entrance of a forest farm clearly reads, No destruction of forests! Violators will be fined! One day, a nearby villager Yang went to the forest farm to cut down a tree and was waiting to be transported down the mountain by the forest ranger. Zhang found that Zhang not only criticized Yang, but also asked for a fine on Yang. Yang was dissatisfied with the fierce debate between the two sides. Yang said, I cut down a tree, not a forest, you should not fine me.
Zhang's logical rebuttal is that those who destroy the forest will be fined. A tree you cut is also a forest.
