I should probably add a comment here, because I'm personally very sympathetic to these theological/spiritual ideas. Scientific or natural pantheism, the Gaia theory and similar perspectives do not supply an alternative explanation to natural processes, but see the natural processes as sacred. The interconnectedness of living creatures, which is a sound ecological principle, is not so much expanded upon as it is given a more spiritual meaning.

Another feature of scientific pantheism, which adds an ethical dimension to it, is that from the acknowledgment of nature as sacred comes a moral requirement to respect nature. In that sense, commitment to ecology and, to some extent, to social justice, becomes a spiritual directive in addition to being a humanistic one.
