Arguably one of the most influential American poets, Walt Whitman (1819 - 1892) was a humanist - and a lover of nature.
In his poem "World Below the Brine", Whitman takes us on a journey beneath the sea surface, first to "forests a the bottom of the sea" and eventually ending with the splendour of some of those animals that live beneath the waves.
