I would say it's gonna take quite a number of years to get us on a different track than killing all these animals. We shudder and shake to think we won't have any meat....but, eventually, the whole earth will come to this idea, as the galactics have told us that there are different ways to "eat". replicators, for one. We have no idea what lies ahead. Just keep your head on a swivel and hold hands with your heart.
