I enjoyed this. There's a very effective juxtaposition here between ecological and human injustice, although I suppose it isn't a juxtaposition really. Exploitation of living creatures is exploitation of living creatures, and while I know historical treatments of human biology have often led to some demographics being treated as closer to animals than others, I think that we can still be disgusted by mistreatment of each and there's no exclusive limit on that. (Unfortunately so, as I'd like to entertain a great deal less disgust than I do, but alas.) That being said, I often found the poems about animals here to be more affecting than the poems about people. Perhaps because those animals appeared more individualised? The images of the elephants in particular... There's some interesting crossover, however, as in the poem "the bear" where a displaced bear is processed as if he was a refugee. It's really all constructed very cleverly.
