I think that a solid conclusion about Wordsworth's love for nature would be to underscore irs elemental position in his work. Quoting from his Preface to Lyrical Ballads might help here. Wordsworth makes clear that the love of nature that he embodies is part of his pursuit of poetic beauty. The subject matter of his work was consistently the display of "humble and rustic life." The Primitivist philosophy he advocates is rooted in a love of nature. It is the realm of perfection that enables the viewer to "see into the life of things." It might be good to integrate these ideas into your conclusion because it helps to underscore his basic philosophic tenets in regards tot he role of nature in his work and the love he holds towards it. For Wordsworth, the driving force of poetry was to recapture a "state of nature" where human beings and the world around them was devoid of corruption and impurity that exists now. The reverence for nature is a part of this. Bringing this out in the conclusion of the paper helps to make clear this fundamental precept his philosophical and poetic positions.
