Man has been abusing and misusing nature for his own selfish needs. People cut down forests to make place for houses, offices, malls etc. Ironically, people also then keep plants and trees inside their homes. In the poem, the poet describes a scene where the trees that are inside homes are now moving out into the forests where they belong. This represents nature’s retaliation to its mistreatment at the hand of mankind. If mankind continues to misuse the gifts of nature, nature will find a way to rebel and punish mankind.
