    • Invasive Species

      When the Ticket Woman is speaking with the Cabbage Merchant, she mentions that a cabbage slug would ruin the ecosystem of Ba Sing Se. This is a reference to a term in ecology known as Invasive species. It occurs when an organism is transported from its native land, by a human, human invention (i.e. ship), or animal, to a new land. There it will have no natural predators to it and will have free reign to grow and expand with little to no hindrance. An example of an invasive species would be the Chestnut Blight Fungus.
