Check Genesis 2 (3?) where God declares that man is to be a steward of the earth's plenty. We are obligated to not waste the resources, as God's steward. And, our stewardship is not more important than countless other God-ordained laws.
Here's where the paradox begins:
Do I buy a small car to save fuel or a large car to protect my family? My family is more important than inert oil in the ground.
Do I purchase organically-grown food or that done by agribusiness? Well, the agribusiness food is far cheaper and less prone to spoilage (especially after irradiation). It will cure hunger in the third world far faster than liberals ever will.
Etc., etc. Being a good steward does not mean toeing the liberal line on the environment.
