Humans and countless other migratory animals have traveled long distances, and often transported other species within their migratory movements as they expand their territory. In evolutionary biology, species recede and advance in pulsing patterns as climatic changes occur more rapidly than their ability to evolve and adapt to changing circumstances. Natural storm events such as hurricanes and floods have been known to redistribute species thousands of miles, often as seeds and spores surviving in water. As we approach the sixth mass extinction of planet earth, and the dispersal of exotic species have been primarily attributed primarily to anthropogenic disturbances, is it logical to label certain highly adaptable species as “invasive”, “noxious” or “alien” when they may be the best suited for survival in some areas? The use of the term invasive species was first coined by Charles Elton in 1953. Elton was highly influenced by a fellow Oxford student, Alexander Carr Saunders, secretary of the Eugenics Education Society, which promoted the study and practice of selective breeding in humans. Eugenics also suggested pseudo-scientific notions of racial and ethnic superiority and was crucial to Nazi scientists who justified genocide and human experimentation through this subject. Much of this prejudiced mentality towards living organisms migrated into the sub discipline of invasion biology. Terms such as genetic pollution, which are still used today, have the heritage of a hate-based philosophy, but recently has come to be associated with Genetically Modified Organisms and their spread into organic crops and wildlands and may pose the greatest threat of any “invasive species”. This sub discipline is controversial within ecology and has far reaching ecological and economic results. Many of the species responsible for the highest loss of diversity, and covering the largest areas of earth with monocultures are factory farms and monoculture crops, most notably, corn, soy and wheat have displaced more native speies than any other organism. Some figures suggest that invasive species cost Americans $136 billion annually, about a third of which comes from herbicide use in conventional agriculture and raises the price of food. In Canada alone the herbicide industry grossed over 26 billion in 2004. Chemical corporations stand to lose billions if a more relaxed stance is taken towards invasive species, and governmental eradication programs could loose funding and lay off staff. Recently there has been some research into the possible benefits of of some introduced species. Beneficial relationships between introduced species and native have often been overlooked and understated. They may provide forage for both native and domesticated animals, cover exposed soils preventing erosion or remove toxins and algae from human sources of pollution.
