Could humanity become an integral part of Earth's ecosystem instead of behaving like wingless locusts with prehensile forepaws? Sure. Will it? Only by demonstrated necessity.
What does that even mean? Locusts are an "integral part of Earth's ecosystem".
Of course this seems to be buying into a mystical notion of "ecological balance" rather than the complex, chaotic state of dynamic processes ecosystems actually have...
In this metaphor, humans are the locusts: incapable or at least unwilling to maintain a state of equilibrium with their ecosystem and consuming all available resources until those resources no longer support the population. The difference is that human behavior is cultural rather than instinctual.
