Species of environmental activist (Gimius Limelitius), that sadly is nowhere near the endangered list. Considers itself waaay above any kind of requirement to deal in accurate information, to think rationally, or to treat the opposition fairly. Exists across a range of habitats, including fields of actually or allegedly transgenic crops (preferred activity: uprooting), banks of TV cameras (preferred activity: indulging in purple and impassioned pleas to rest of population that generally involve mentioning children) and rooms set aside for public debate with scientists (preferred activities: screaming, name calling, pulling hair and storming out in a huff). Its favourite habitat, though, is up a tree, preferably as high a tree as possible and especially one that stands along the route of a planned motorway. The species reproduces itself by way of books and websites featuring the kind of fuzzy logic once associated with the likes of Charles Berlitz. It associates mostly or entirely with its own kind and its only predator is Homo Scientificus Rationalis, or so it claims. Often covered in carbuncles, some of which may be mistaken for quartz crystals, and may smell musky or musty, depending on the weather. Claims to be herbivorous. Among biologists, opinion is divided between whether this species represents part of the order of mammals, or that of reptiles. Others say there is just something fishy about it.
Look at those ego-warriors, uprooting your man's sugar beet and claiming to be out to save the Earth.
