Invasive or Exotic Species :: Environment, Plants, Animals

Today, Plants and animals usually can travel virtually the world in a matter of hours to days through planes or by ship. Usually their charge is harmful, yet some scientists believe that they can actually be a catalyst for biodiversity Invasive or exotic species keep up altered the Chesapeake talk region with both a negative and positive impact.Exotic species be plants, animals or microbes that stir been transported from one geographic region to an separate. (5) They are locomote from an area where their evolution balance is set, into an area where they may not have any natural competitors. Invasive or exotic species can crap a major impact to our environment. They can put ecosystems at peril by changing an entire environment, supersede other species that are native-born to the environment, and even damage human activities such as fishing. (1) Once introduced into a new environment, Invasive species throw off the ecological balance of the area. They may not have natura l predators and can outcompete natural organisms giving them the hazard for fast growth throughout the environment (The nature Conservancy, 2004) Invasive species are even the one of the top reasons why some of our endangered species are threatened. The graph to the left shows that about 50 percent of threatened or affected endangered species were due to these exotic species In the United States unaccompanied in that location are many an(prenominal) invasive and exotic species already establish According to the Exotics in the Chesapeake, At least 4,500 species have established free-living populations in the U.s. (3) These species have even shown through in the waters around usI do believe that these Invasive and Exotic species have even altered the Chesapeake Bay region and that these alterations arent always predictable For instance, Oysters in the Chesapeake Bay have suffered since their parasites Dermo and MSX were introduced into the area as exotics.(3) Oysters fundamen tal agency is to abolish the algae in the water yet with the decline of oysters there is a major demolish in the bay ecosystem. (3) This is not righteous affecting the bay, it is also affecting oyster fishery bringing frequently economic loss. (3) Other examples would include the mute swan which acts aggressive towards other birds in the area. (2) Even though there are many downfalls to these species many could bring good. The Hydrilla plant might take control and replace other native plants yet can also benefit the bay.
