Answer:
Unlike staple crops, cash crops are grown to be sold for as much profit as possible. Europeans brought plants from Asia, such as sugar and coffee, to grow as cash crops in the Americas. They also turned American plants, like tobacco and cacao, into cash crops. European colonists learned that the best way to make a profit was to farm huge numbers of the same species of plant, also called monoculture. Then, the plantation systems forced enslaved people to farm vast fields of monoculture cash crops.
Cash crops and plantations were profitable because Europeans established global trading networks. European merchants sold American-grown cash crops in Asian and European markets at a huge profit. Often, they brought along new crops like potatoes and maize. This sped up the transfer of new foods and cultural tastes around the world.
