This movement of species crosswise different geographic locations is referred to as pathways and motley man-made and natural factors contribute to it . The human activities include the thought movement of one or more genetic species crosswise different locations to ensure biological diversity . These are sometimes governed by financial considerations to harvest more of one or more type of species . But there effects on the already existing species need to be evaluated before labelling them unspoilt or harmful because foreign species have been known to strikebreaker out local species in the past . These are the label as invasive plants as they disturb the natural purlieu and take a threat to biodiversity .
