Both poems highlight the conflict between man and nature, but from opposite perspectives. 'On Killing a Tree' deals with the destruction of a tree, focusing on human cruelty and nature's resilience to survive. In contrast, 'The Trees' focuses on nature's liberation, where trees actively break out of human confinement.

In Rich's poem, the trees are imprisoned inside a house. They struggle to escape: the roots work to disengage from the cracks, leaves strain toward the glass, and boughs shuffle like 'newly discharged patients'. The trees stumble forward, breaking the glass to move out into the night.

Conversely, Patel's poem portrays a tree being killed, yet it fights to survive the assault. While Patel's tree is a victim of human violence struggling to stay alive, Rich's trees are active agents refusing domestication and reclaiming their wild space in the empty forest.

Ultimately, both poems show nature's enduring power. While 'On Killing a Tree' highlights nature's resilient survival against human attempts to destroy it, 'The Trees' celebrates nature's powerful urge to break out and return to its natural state, leaving human confinements behind.
