People where not fully in control of nature

The human species is just one of many that inhabit Planet Earth. Craftsman of nature and the product of its own, the human species is not just another form of life in this vast but limited world, but perhaps the only one capable of breaking the balance of the delicate planet on which we live.

The use of nature as the object of reason-guided human conduct, not directed solely by the instinctive satisfaction of needs, has brought man's relationship with nature to deleterious levels for nature itself. We are able to reason and this has led us to attack and destroy ecosystems, because we act with the aim of achieving other goals. All species harm nature in one way or another, and all animal activity and movement has - to a greater or lesser extent - a destructive impact on the environment.

However, humans, through the ages, and guided by his ability to master the conditions of the environment that give him reason and reasoning, gradually increased this aggression, no longer being controlled and subjugated by the surrounding environment, becoming the status controller and later destruction of their own connections.

i think it is the third one.
