The Jungle can have different meanings depending on the context: 1) The jungle, in the biological sense, is a very dense and wild area of tropical rainforest (Though even in this case, the jungle is a general concept rather than a specific one, as there are many different tropical rainforest types). Generally speaking, jungle exists close to the equator and is characterised by high temperatures, high rainfall and high biodiversity on the plant and animal. Join me in the jungle. I will be your king and you will be my friends.
