The word jungle came from a Sanskrit word, “jaṅgala”. It means “rough and arid”. A jungle may be land or area with a particularly dense quantity of vegetation. This dense forest of vegetation includes several trees and plants found in tropical climates. They’re also home to high biodiversity and many unique species but are also some of the most fragile ecosystems on Earth. A jungle appears overgrown and is sometimes in a particularly hot part of the world with loads of rainfall.
