The implicit implication when saying something needs to be fixed is that the thing is broken. A stick can be snapped, as can a human bone, when pressure is exerted with sufficient force. Machines can stop running because a crucial part becomes defective, taking down an entire system. Earth is a highly complex system with checks and balances, but I don't envision Earth being broken, considering it is a self-healing system that adapts to variations, creating new realities as elements evolve and the system dynamically adapts, creating new realities.
