A quote from Henry David Thoreau

[Stop_the_War]

I have no doubt that it is a part of the destiny of the human race, in its gradual improvement, to leave off eating animals, as surely as the savage tribes have left off eating each other when they came in contact with the more civilized.

[Swede]

1. Yeah,about a century after the last war.

Until then don't hold your breath.

[BBradley]

2. Only when they stop eating each other!

3. Thoreau also advised a depressed acquaintance to commit suicide

And then expressed detached surprise upon learning that the man had indeed killed himself.

[Fenris]

4. Animals don't seem to have a problem eating other animals.

The carnivores/omnivores at least.
