We should distinguish between instrumental value and intrinsic value.
Christian view is universe is intrinsically valuable because it is made by God.
Even if average ppl are involved in environmental movement, they can only describe the value of environment in utilitarian terms.
People are wrong to think of the biblical environmental ethics is being anthropocentric. It's theocentric.
Contemporary environmental ethics is bio-, eco- or gaia-centric. None of them can answer more fundamental questions only theocentrism can.
