Christians should desire to care for animal life and the environment, but because the earth is the Lords and he requires it. The true salvation for the planet and animal life will be found in the Second Coming of Christ.
A quote from Dr. Andy Woods about the sanctity of our lives as Christians as opposed to mere quality of life.
Balance can be a concept that is used to justify unbiblical belief and practice, but it is still needed. We must know, proclaim, and live all the Word of God. We must be balanced in all our doctrine and life. This is what it means to have a truly Biblical worldview.
