The Southern Caribbean is a group of islands that neighbor mainland South America in the West Indies.
Saint Lucia lies to the north of the region, Barbados in the east, Trinidad and Tobago at its southernmost point, and Aruba at the most westerly section.
[2] The majority of the islands are covered in tropical rainforests and swamps; the densest of these are in Grenada, Saint Lucia, and Tobago.
Islands such as Aruba and Barbados occasionally suffer droughts, while Grenada receives a great deal of rainfall.
The natives disappeared due to various reasons, including diseases brought in by Europeans to which they had no immunity, warring, enslavement and the removal of the natural resources upon which these tribes depended.
