Step-by-step explanation:
The country with Carriacou as its second largest island, along with Petit Martinique, Grenadines islands such as Martinique, Ronde, Diamond Island, and the underwater volcano Kick'em Jenny, is Grenada. These islands are part of the Lesser Antilles located in the Eastern Caribbean Sea. The Lesser Antilles is a region known for its economic dependency on tourism and agriculture, with issues such as low profit margins on exported products being a prominent economic challenge.
Despite the lucrative tourism sector, other economic activities such as agriculture have traditionally been vital for islands like Grenada, which exports spices, including nutmeg, and other products like bananas and sugar. Yet, due to fluctuating international market prices, the profitability of these exports can vary greatly, sometimes intensifying economic hardships for places with increasing populations and limited job opportunities, such as Haiti.
