Genesis 1:28 says, "And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth." To subdue the earth does not mean to destroy it, but all things were created for the sustaining of human beings. The movement to kill off the human race is not a thought of God. We have a responsibility to take care of things, but ceasing to breathe is not one of them.
