Ha, joke's on you Earth. We're slowly but surely killing you, and our inexorable march towards technological advancement will allow us to escape your grasp.
Earth has survived several mass extinctions and life has occasionally majorly altered the environment (though at a much slower rate). I doubt Earth has any qualms wiping us out through natural causes or through our own actions. Hell fossil fuels are just the remains of the corpses of life long since past. We live on essentially a massive graveyard and there is no reason to think the Earth isn't perfectly content letting us joining in and sharing the graves with the rest.
We're much further along on that than you think. The largest orbital structure we've built is the ISS and we're at the point where there is interest in simply abandoning it. We have yet to establish much in terms of actual facilities in orbit besides research labs and demonstration projects. We also have not resolved preventing Kessler syndrome and yet we're dumping more and more satellites into orbit. While costs of launching things into orbit has gotten cheaper, a lot of that is launching materials into lower orbits and the cost of launching astronauts is still around $55 million per person. Furthermore to be able to leave Earth for good we'd need to be able to construct artificial environments, but I don't believe we've successfully created any perfectly closed loops for those, which would mean we'd still have to manage bringing materials in to maintain any such environment. That means a dependency on Earth which is the only place to obtain these materials, especially those for sustaining biologicals.
Also with the changes happening because of climate change putting pressure on us, I believe we're heading into a period of great instability. Getting into space and leaving Earth will be running against the clock of when some major disaster is going to hit. The problem is that there are many ways that disaster could take form. These changes in climate can encourage new diseases to appear, whether one that infects us or infects say some of our major crops, either would plunge us into chaos. Imagine what would happen if a new disease starts decimating one our major staple crops (say rice or wheat). Potable water will also become much scarcer and fights for them is inevitably going to happen. Our hunger for water, especially for our agriculture, is massive. We've literally dried up a sea (see Aral Sea) and sunken ground levels (https://en.wikipedia.org/wiki/Central_Valley_land_subsidence) for water. It's highly likely that as pressure mounts on controlling access to this water, that we're going to have war over it. We can only hope that we don't end up knocked back several steps here on Earth before we can even take a step forward in space.
So there are two sides to her? Like Jekyll and Hyde?
Scary
Not even Jekyll and Hyde situation. She straight up don't care. As people said before, 'the opposite of love isn't hate, but indifference'. 99,9999999999~% of the organisms that lived on earth had died before our time; do you think with us being sentient she would care for our demise (on our own hand)? Earth survived multiple extinction events, including supervulcanoes, meteoric impact, ice age and so on and so forth---and each time, life finds a way to continue. Humanity are given a chance to survive extinction because they managed to be advanced enough before the next extinction event, but that's not because earth cares for them.
