To show love, thanks and respect to God, we have to first and foremost honor His Words in Holy Scripture and in the Ten Commandments.  Yes, God created all human beings and put us here on earth temporarily to love, serve, adore and obey Him.  Human beings, created by God, have decided that they know better and have decided that to destroy an embryo in the womb of his/her mother is okay, but killing anyone outside of the womb is a crime, punished by law.  We think we are better than God and have decided to deliberately ignore God's Word in Genesis and then repeated by Jesus (during  His three years of public life) in Matthew, Mark and Luke regarding marriage.  How can we talk about destroying God's earth without mentioning how we are destroying ourselves (physically, spiritually and mentally).  What about the sin of impurity (against chastity)?   We cannot save the earth if we do not first seek to save our souls by repenting, asking forgiveness and stop abusing the gift of sexuality.
