Perhaps the idea that God gave us the planet to exploit for its resources and animals to treat however we want, thus we shouldn't care about overtaxing the oceans and gas supply, granting animals rights, or concern ourselves with global warming, which God wouldn't let happen.
A lot of Christian churches actually support a type of environmentalism under the idea that God gave man stewardship over the earth, which comes with the responsibility to keep it up. It's His creation, after all (under this belief).
