There is no question that Christians should care about the environment. However, the infantile notion that the planet needs saving or could be saved is not what that means. This notion rests on the idea that the planet has some sort of intrinsic value, that it has the capacity to care which configuration it ends up in, and that there are things we can do for the sake of the planet just for the sake of the planet.
The interesting thing about Christian care for the environment, especially if we take the Scriptures as our guide, is that this ‘human interest’ is front and center. Genesis 1:26 has God putting mankind in charge of ‘the fish of the sea and the birds of the air, over the livestock, over all the earth, and over all the creatures that move along the ground.’ This we can properly call stewardship and as we see from the text, the value of humans and the earth is set by God, and in this equation, the earth is placed in subject to Humanity.
