Camels

Used in the 1800s by settlers in the Australian Outback, camels fell by the wayside once automobiles came along — or so the old-timers who ditched them hoped. Unfortunately, feral camels now number in the millions in Australia, eating their way through native vegetation and even terrorizing towns as they search for water in drought-stricken regions. Some camel haters even blame their intestinal gas (i.e., methane) for climate change and propose culling herds of feral camels from helicopters or corralling them for slaughter.
