Wordsworth was really into nature. You know, like, really into nature. We don't know if he actually went out and hugged trees and stuff, but he certainly got close to them whenever possible. Much of his poetry is in the pastoral mode (basically meaning that it had to do with the beauty of nature and the glories of the countryside). Even in this poem, misleadingly titled "London, 1802," the poet manages to bring up natural imagery and doesn't once mention the city of London. Wordsworth uses images of nature as both positive and negative forces in this poem, framing both Milton and England itself in the natural world.
