This drew immediate attention when I posted it to facebook and another group with a much larger following reposted it. I think it's worth sharing both with other vegans/vegetarians so they can share it, and also in non-vegan groups, it is something different that catches the eye and isn't well known, give it a go.
It's amazing how many people are genuinely confused and think that the area shown on the map as "built up" is supposed to be built up, and don't understand that it is a proportion of the total area randomly allocated. It may be worth explaining this because some people actually look at the map and are genuinely confused and think that the area that says "cereals" is literally corresponding to the actual geographical area where the cereals are grown! In spite of this confusion I think it's worth it, because you will get way more attention with a graphical image than if you shared some stats.
I bet this is true for other developed, densely populated countries like Japan, South Korea, Netherlands, Belgium etc.
