Shinto. It lacks the problem of organised religions, although the Japanese state has previously put work in to create state Shintoism it doesn't really work the same way other organised religions do. It's very in tune with the natural surroundings and it cares about taking care of the environment because it is the environment that produces the Kami, spirits that inhabit it and come from objects/environments.

I see it as more of a spiritualist connection to our surroundings and even if you sincerely believe that the spirits are real they're never divinely perfect and are many of them are fought against entirely by humanity because they're obviously not good.

It works well.

Honestly though I've always thought the problem is not really religion or spirituality but organised religion functioning as an arm of the state.
