Final answer:
In 'The Great Gatsby', the green light symbolizes optimism, the pursuit of the American Dream, and money, but it does not represent nature.
Step-by-step explanation:
The green light in the novel 'The Great Gatsby' symbolizes several themes, but the one it does not represent is nature. This green light is most famously known for its representation of optimism, the never-ending pursuit of the American Dream, and the allure and false promise of money. In the context of the novel, the green light is situated at the end of Daisy's dock and represents Gatsby's hopes and dreams about the future. However, nature, as a concept, is not principally symbolized by this green light. It stands more so as a beacon of Gatsby's aspirations and the American socio-economic and class dynamics.
