Christian environmentalism?

Presidential elections typically resurrect the same tired issues. Those on the right are often limited to abortion as the primary political narrative, while many on the left continue to dream about bringing us one step closer to socialism with their talk of "taxing the rich" and "universal" this and that. But what about the environment? To whom does that issue belong? Do Christians care about the environment?

The National Council of Churches (NCC), an ecumenical amalgam of churches, may care so much about the environment that they have little concern for either the eternal souls of people living in nature or for submitting to the authority of Scripture in all areas of life. The NCC has an eco-justice commission that includes "all ministries designed to heal and defend creation, working to assure justice for all of creation and the human beings who live in it." On the surface this sounds reasonable perhaps, but at the end of the day we are left with the proverbial questions of application and enforcement.

The NCC grounds its position in the Scriptures:

First, we read in Genesis that God beholds all creation as "very good" (Gen 1:31) and commands us to "till and tend the garden" (Gen 2:15). Humankind is called to stewardship of the commons. Second, we read in Psalms, "The Earth is the Lord's and the fulness thereof" (Ps 24:1). The bounty of Creation's gifts must serve the common good of all. Third, we have a paramount obligation to "defend the poor and the orphan; do justice to the afflicted" (Ps 82:3) and to care first for "the least of these" (Math 25:35). Care for God's creation particularly requires protection of vulnerable life. Finally, we have an obligation, in prudence and precaution, to sustain the future well-being of all life on Earth, God's "covenant which I make between me and you and every living creature for perpetual generations" (Gen 9:12).

In an open letter to U.S. the NCC calls for national repentance because "we have abused and exploited the Earth and people on the margins of power and privilege, altering climates, extinguishing species, and jeopardizing Earth's capacity to sustain life as we know and love it."

Is it just me or does the NCC need some help on environmental issues? What is our environmental responsibility as Christians, as the church?
