The successful development of one set of plants alters the conditions of success, paving the way for a succeeding set of new plants. Weeds create the conditions for bushes, bushes create the conditions for trees. Weedroids exploit every opportunity to gain more resources. Dendroids exploit every opportunity to get more use out of available resources. Members of a weedroid organization never worry about its mission.
Mission statements are multifarious euphemisms for lack of focus.
In the bounteous environment of weedroids, life is not just dog eat dog, it's hog eat everything. Weedroid members and units compete with each other to get more funding and space. Each harbors information and protects turf. For example, the academic departments in Weed University strive to gain more faculty positions. More positions promise less teaching, more grant applications and greater visibility.
