What is the theme of the poem the tropics in New York by Claude McKay

The theme of the poem "The Tropics in New York" by Claude McKay is the contrast and tension between the vibrant, colorful nature of the Caribbean and the cold, bleak reality of life in New York City for African Americans in the early 20th century. The poem explores themes of homesickness, displacement, and the longing for a connection to one's homeland and culture. It also delves into the harsh realities of racial discrimination, inequality, and the struggle for racial identity and acceptance in a foreign land.
