Vegans are more consistent than meat-eating humanists, which is good, but it's hard to avoid contributing to the problems of consumerism and human progress (against the balance of the ecosystems), unless we live in a cave. So my criticisms of all of us along those lines stand.
That Unity project is certainly an interesting way of looking at the problem. I'm interested in the spiritual monism that might underlie that plan.
I notice, though, a disappointing concession made at the end of that intro video, where it presents the long list of narrators, many of whom are movie stars. The list doesn't exhibit unity but clearly distinguishes the A-listers from the B-listers, by putting the names of the A-listers in bold. That unfortunate lapse nicely exhibits why social divisions happen and why global unity is very unlikely without a major transformation of our cognitive capacities.
