Watermelons – what communist environmentalists are called – why? – cause they are green on the outside and red on the in. James Delingpole from the UK telegraph makes some salient points in his post – Carbonhagen hangovers. Yet all over the world there are examples of exploding watermelons! Seems like the connection between environmentalism and socialism isnt new. Even Chavez clears the air on why green really means red!.
