No. God’s original plan was for us to eat only fruit and vegetation (Genesis 1:29). In Malachi 3:6 it states that God does not change. God has never changed and even now he wants us to show mercy to animals and obedience to his original instructions. You have the power right now in this life to change. With God all things are possible (Matthew 19:26). For a more detailed explanation about what transpired between God and Noah just after the flood, read Permission and Going the Extra Mile. For a more general understanding of God’s unchanging attitude toward animals, read Love God, Love Animals.
