Nope. The hubris of your thought is that humans are somehow separate from the planet, better than the planet, and can fix the planet.
Like all Flora and fauna, humans are a product of the planet. Humans are part of nature. The acts of that species are as much of nature as anything else. The earth will take care of itself. If the human species becomes such an infestation that harms earth, nature will find a way. Always has. No species on any planet was is or will be immortal or bigger than it's progenitor
