Selva refers to a type of tropical rainforest found in regions like South America. These forests are characterized by high biodiversity, dense vegetation, and a warm, humid climate. Selvas play a crucial role in regulating the Earth's climate and are home to countless species of plants and animals. The term "selva" is often used interchangeably with jungle, although jungles typically have more undergrowth. Selvas are vital for ecological balance, providing habitats for wildlife and contributing to the global oxygen supply. They also support indigenous communities who rely on the forest for their livelihoods.
