The poem seems to ask, instead, to leave the natural areas intact.
It would be better to create a reserve, where all types of animals can live together in harmony.
Dickey utilizes many different literary features to get his message across, namely his choice of structure, vocabulary, and imagery, though there are many more.
The text itself is very clearly about both predators and prey, how they interact with each other, their habitats, and the process in which they live and die.
What does the structure say, if not that being in a 'cage' (rigid structure) is unnatural for animals?
This is especially clear in stanza six, where two lines from stanza five occur in stanza six."And crouch on the limbs of trees,/ And their descent/ Upon the bright backs of their prey." clearly refers to a predator stalking its prey.Only the first two lines of stanza six describe the predators; a continuation of the sentence in stanza five.However, a sure start is with the overall structure.There is no rhyme scheme, the themes bleed into each other, and the stanzas have different lengths.The main theme explored is the idea that an animal's heaven is right on Earth, in its natural habitat.Furthermore, the poem could serve as a warning to humans that destroying the planet is not only dangerous to our own continued existence, but it brings up important moral issues concerning the animals who also reside on our planet."May take years/ In a sovereign floating of joy." gives away its subject with the word 'sovereign', a word of power.The prey, obviously, is not empowered, and so it refers to the predators.Further, the two lines, "May take years/ In a sovereign floating of joy." are about predators, while the rest of stanza six is about their prey.This not only shows a relaxed structure, but that prey and predators being together is a natural part of an animal's life, and to separate them is unnatural.
