The Americas
Explorers and conquistadors brought many new plants to the Americas. They brought European crops such as barley and rye. They brought wheat, which was originally from the Middle East. They brought plants that had originally come from Asia, including sugar, bananas, yams, citrus fruit, coffee, rice, and sugarcane.
New plants created new economies in the Americas. They also contributed to the creation of huge slave societies. By the 1600s, the Portuguese were growing sugar, bananas, and citrus fruit on large plantations in Brazil and the Caribbean. They began importing African slaves to work on these plantations. This was the beginning of a slave trade that uprooted millions of Africans over the next few centuries. Later, African slaves were brought to the American South to grow cotton, tobacco, rice, and other crops.
