Earth doesn't think.

It has existed long before us, it will exist long after us, if it could think it's thoughts on us are little more than "that bug bite itches"

We don't matter to the Earth, never have, never will.

But the Earth should matter to us, not through some idea of protecting it, it will survive basically anything we throw at it, but from the idea of protecting ourselves - we're in a Goldilocks zone and that can reach a point of being too hot or too cold, that we won't survive it.
