CANE TOAD
The Cane Toad was brought to Australia in order to kill the Cane Beetle because the beetle kills or stunts the sugar cane plant. The Australian Bureau of Sugar Experimental Stations brought 100 toads from Hawaii to help the Sugar Cane plant population. Unfortunately they were unsuccessful in killing the Cane Beetle and have spread all over northern Australia. In order to rid Australia of the invasive species scientists sought to find an infectious agent to kill them off but they found that they were also infectious to some native species so the agents could not be used. But still, the toads were causing declines in some of the species in Australia because of the poison the toad produces in glands in their heads. So the Cane toad, although caused great harm to some Australian species, has helped others in providing food for some native animals in Australia.
ASIAN LONG-HORNED BEETLE
This species was accidentally introduced to America and poses a threat to the trees in urban and suburban areas because it eats the trees. Over 30,550 trees have been cut down and destroyed in order to stop the spread of these beetles. People have also tried to use insecticides and shipping restrictions to help the population of the beetle subside.
We should be concerned with invasive species because they hurt our environment. In doing this the invasive species push out all of the indigenous species disrupting the natural habitats of everything in the country and even the whole continent. This could then lead to the disruption of the economies of many countries because the produce would be different because of the invasive species involvement.
