4、uction of Exotic Species Overexploitation More Factors,12,Habitat Destruction,Our planet is continually changing, causing habitats to be altered and modified. Natural changes tend to occur at a gradual pace, usually causing only a slight impact on individual species. However, when changes occur at a

5、 fast pace, there is little or no time for individual species to react and adjust to new circumstances. This can create disastrous results, and for this reason, rapid habitat loss is the primary cause of species endangerment.,13,Introduction of Exotic Species,These species are introduced into new en

6、vironments by way of human activities, either intentionally or accidentally. These interlopers are viewed by the native species as foreign elements. They may cause no obvious problems and may eventual be considered as natural as any native species in the habitat. However, exotic species may also ser

7、iously disrupt delicate ecological balances and may produce a plethora of unintended yet harmful consequences.,14,Overexploitation,A species that faces overexploitation is one that may become severely endangered or even extinct due to the rate in which the species is being used. Due to the trade in
