Dissonance

The Greens revealed their campaign billboards today: images of environmental destruction and the slogan "Love New Zealand". I'm not sure it works. I get that they want to confront people with what they're against - but shouldn't they make it clearer? With, perhaps, a question mark? Or maybe a different slogan suggesting that this is what a vote for them will stop?

OTOH, I'm not a marketing guru, so what would I know.
