"Roll on, deep and dark blue ocean, roll. Ten thousand fleets sweep over thee in vain. Man marks the earth with ruin, but his control stops with the shore"

This quote by Lord Byron speaks to the power of nature and the insignificance of man in contrast. The ocean is described as deep and dark blue, a large stretch that is not affected by the actions of guy. In spite of the truth that guy has the power to destroy the earth, his control stops at the shore. The ocean is a force that is too powerful for man to manage, and no matter the number of fleets sweep over it, they will be in vain. This quote acts as a suggestion of the power of nature and the restrictions of man. It is a reminder that no matter how powerful guy may think he is, nature will constantly be more effective.
