We are only one small cell and the land is just another small cell on this planet and we work together in this infinite interrelationship of processes. Let's come back to something easy to understand. Consider for a moment what happens if we mistreat our own organism, our body. A cut bleeds. A blow to the head hurts.
Smoking probably causes cancer.
Couch potatoes gather moss. We can expect to suffer consequences from this mistreatment. Sometimes, we heal from this abuse. Sometimes a scar remains. Sometimes we do not heal, we are permanently disabled.
