African subsistence farmers are benefitting from the food and money provided by introduction of cash crops
a. True
b. False
Indicate whether the statement is true or false
False
RATIONALE: Although cash crops are important sources of revenue in these poor countries, excessive dependence on them, as with other commodities, can harm a country's economy. The income they bring often goes almost exclusively to already prosperous farmers and corporations. The prices they fetch are vulnerable to sudden losses amid changing world market conditions. The plants themselves are susceptible to drought and disease. Finally, they are often grown instead of food crops, and cash crops do not feed hungry people.
