I hope he gets damaged because I just picked up ALFY , sorry I know that ' s mean <| sep |> How and why is avoidable ? If we all switched to drinking almond milk , we ' d obliterate the almonds from the planet . And , it ' s not completely avoidable . I would cringe to hear a child being raised without vitamin B 12 found strongly in meat and hardly anywhere else . And no , supplements are not a great source to replace anything natural . Not only that , it was cooking for meat that some suspect launched the increase in brain mass , which seemed to be growing steadily but took off around the time man started cooking meat , but they cannot say for certain if that is why it occurred . It ' s only completely avoidable because , via industry , we have created mass amount of processing abilities . While humanity runs strong , now , any simple collapse in the economy can send us back to square one and the fact that humans can think they can rely on a huge factory pumping out almond milk isn ' t going to happen . They ' ll be back to square one . We are always on the verge of going back to square one . Modern day diet can work because man has invested billions into technology that enable vegans to survive on a diet none of their ancestors had .
