To clarify, the words לעבדה ולשמרה are interpreted by some commentaries to refer to spiritual work. Others interpret it to refer to physical work and guarding. The midrash (Kohelet Rabbah) I quoted above does not reference the words לעבדה ולשמרה, but it clearly states that Hashem warned Adam about destroying the world. If you want to explain that as spiritual in line with commentaries on Bereishis, go right ahead if that fits with shmuessen, but you need to first acknowledge the plain meaning of the midrash. See Etz Yosef who understands the midrash as referring to the destruction of the physical creation.
You said in passing that nothing you have learnt includes environmentalism, so I thought you would appreciate having the midrash pointed out to you. If you knew it but disregarded and/or reinterpreted it to fit your politics, then as I said, I’m not the orthodox police, but don’t act like you are either.
