Point taken, Bree, a short life as a museum exhibit doesn't need to spell death for a wild plant if it's responsibly re-homed after the event. But I'm still puzzled by the concept:
...It was inspired by a dystopian image of a world where nature could only be seen in designated spaces, like animals in zoos.
So let me see. You take your 300 trees, and you charge the people a dollar and a half to see them, and then you say to them: "Listen, my people, what you are witnessing is actually a mere travesty of the great woodland outdoors that you could see for yourselves if you could only be [expletive deleted] to get into your cars and go and visit them. Pretty, aren't they? But it's still ugly that we're locking them up like animals."
It's better than nothing, I suppose. When I taught in Birmingham in the seventies, there were kids who thought it was pretty revolting that milk came from cows. Their mothers had told them that it was all made in milk factories. But I'd have thought the land of Sound of Music would have a healthier and more direct relationship with its natural heritage?
