Concerning the animal question, the Bible is clear and consistent: mankind was supposed to faithfully steward God's creation and all that lives in it. Man has utterly failed, which is why you can't even go in the woods without getting 20 ticks, and practically every plant you find is invasive and not good for food. The present Earth is falling apart, due to man's imperfect sin nature.
The confusion in this discussion arises from a conflation of mainstream Republican thought with what the Bible actually says.
Edit: "God destroys those who destroy the earth." ~ Revelation 11:18. We see a consistent message from the beginning of the Bible (Genesis) to the end.
