Yes, the poem presents a conflict between man and nature. Man is causing deforestation by cutting down the trees for his own use. On the other hand, he decorates his house with the trees. We are damaging our environment without even thinking about the end results. By clearing up the forests, we are endangering ourselves. So is with the animals too. We are ruining their natural habitat and killing them for our fun or food but on the other hand, we are keeping them in the cages on the pretext of safeguarding them by making sanctuaries and zoos. So, it is true that we are in a direct conflict with nature and making the other living beings prisoners, be it the trees or animals.
