I would argue that meat-eating was most likely the original sin and that meat eating has and will continue to play a major role in future disease epidemics, pollution, and global warming. Scripture clearly shows God's desire to bring back the vegan/vegetarian diet He started out with in the beginning ( Genesis 1:29-30 ) and plans to end with as described in Isaiah 11:6-9 . You're not going to be slaughtering animals for food in the Kingdom of God (run by Jesus Christ) on earth as is made clear in verses 6-9 . "They will neither harm nor destroy on all my holy mountain" shows us a final change for the better. It's my belief that the food God did not want Adam and Eve to eat was, in fact, meat and not a fruit or an apple from a "tree of the knowledge of good and evil" which is obviously a symbolic gesture on God's part. Notice how God made clothes from the skins of animals for Adam and Eve after they ate the forbidden food. Genesis 3:21 .
