Please note that it is the inevitable fate of all species on Earth to melt into puddles of lava when the sun becomes a red giant. Humans are also the only species on Earth with the potential to change that and preserve Earth's ecosystems, and probably the only one with that potential Earth has ever evolved.
(No, seriously. The list of required traits for intelligence is LONG. Dawkins is quoted as saying it is reasonably unlikely Earth will evolve another intelligent species if we go extinct.)
To personify the Earth, think of humans as an investment to save Earth's biomes from inevitable death. I'd say that investment is worth some serious risk. Our planet has certainly had mass extinctions for lesser causes.
