What is the central idea of the poem “The Trees”?

The central idea of the poem is the conflict between man and nature. A plant is bought inside the house when it is a sapling. But as it grows into a tree. It gets suffocated with the limited space available. So it departs to feel free. The tree is thus moving out to occupy the now empty forest, made so by man’s indiscriminate felling of trees. Humans must understand the negative impact of their actions on nature and mend their ways before it is too late
