No. I fully respect the Earth and understand that it doesn't need protecting nor is its existence predicated on a certain climate. The Earth could, and has hosted climates that would be dire and unfathomable to us, it makes no difference to it.
It makes a difference to us. Nobody cares about the Earth, they care about their own habitat and can't distinguish between the planet and their ego.
The Earth only ceases to be if the periodicity of its orbit, rotation, or axial tilt are substantially altered and therefore could no longer maintain its shape or place in the solar system or if it was totally obliterated by say the Sun exploding. Nothing else.
Emotionalism and vulnerability don't exist without us and the Earth is not something in need of care. Respect maybe, but that's a different story.
