"Armies of creatures are on the move in places where they don't belong. They kill the animals and plants that get in their way. Is there a way to stop them?"

Make the following comments on the article: Respond to others also Green338: There are more than 50,000 alien spiecs living in the united states alone. There are many animals that can kill a crocidile like the cane toad. There are some animals that are living miles from their home habitat. Most leave a trail of destruction. The Austrilians have spent nearly 15 million dollars on trying to get rid of the alien spices but mostly the cane toad.

 * blue15131 || Alien species are entering the United Stiates and leaving a trail of destruction. These species are killing other animals and plants in this area. Once these species enter the United States they spread quick like the cane toad that lays up to 30,000 eggs at one time. THe United States can not get all of the species out and it is costing over 15 million dollars to get them out and progress is not going well. ||
 * red 373 || I think that people should now that there are animals on the up rise. There population is getting bigger day by day because there is nothing thatr can stop them. Like the cane toad. When the cane toad is sollaowed it leaves a poisous liquid in the animal and then the animal dies. the cane toad can kill a cocidile.The u.s is now homes for more then 50,000 alien species ||
 * yellow367 || people need to start trying to stop invadors from disrupting ecosystems ||
 * green347 || its about different kinds of animals that were brought here and how they cause different problems for us and disrupting the ecosystem. ||

Please include your ID || || I want to know how animals devolp poison in there own body. Also I want to know why sciencetist cant just get all the animals back to there native land with the technolgy now a days. || green347: it is hard for the scientists to gather all of the animals because they have populated greatly. || || I would like to know why the nutrias teeth are orange? || blue15131 there teeth are orange because of a pigment made of iron. || Please include your ID || with or studythe animal to make sure its safe with all the rest of the species that would have solved the cane toads and nobody should have wild animals so nobody releases dangerous species in the wrong spot. ||  || Green338: Ecosystem is all the living things and non living things in an area

 * blue15131 || I learned that over 50,000 alien species are entering the world everywhere. Alien species are animal and plants that are unknown to humans in ways and are not native to the U.S. some of these species are good and some are bad. For example the Cane toad is a bad animal because it is poisonous and when other animals eat the toad they die.
 * red373 || I learned that austria spent over 15 million dollars to remove the cane frogs but it did not work. There is more cane frogs now then ever. cane frogs can lay up 30,000 eggs at one time. I also learned that the nutria's large orange teeth are sharpe and that is good for eating threw plants[[image:nutria.jpg width="276" height="312"]] || I want to now why they just kill one cane toad at a time. Also why did the aniamals being. || yellow367: they just kill one at a time because its hard to kill all of them with out killing a lot of other species. and the animals began because they were brought over or hitched on cars and ships. ||
 * yellow367 || I learned that lionfish where brought into the atlantic and are eating coral reef fish. And when a species moves into an area its really hard to remove them.[[image:http://www.wildlife-magnets.com/prodimages/large/red_lionfish.jpg width="330" height="214"]] || I want to know how the lionfish got from pacific ocean to the atlantic ocean || The first reports of lionfish in the Atlantic occurred in the early 1990s, when several aquarium lionfish escaped into Biscayne Bay, Florida during Hurricane Andrew. ||
 * Green338 || I learned that many alien spieces live miles away from their home habitat like the nutria that is native south america.
 * green347 || i learned that alot of animals/species have been causing many problems in different envirorments and they are even killing other species also. Also a couple of them even are poisonous when eatten and may contain a poison that they can use against predators. || i would still like to know how many of them got over here or to where they are now? ||  ||
 * Respond to my question below:**
 * Your Id || What suggestions do you have? || **Respond to others here**
 * blue15131 || I suggest that we find animals that eat or kill the bad, alien species. || not all of them can be eatten because of poison they have in them and some of them don't even have predators because they are so "dangerous". ||
 * red373 || i suguest that we capture the animals and kill them. || blue15131 I think that is a great idea but for some reason we cant and i think that with the technolgy now a day we should be able to. ||
 * yellow367 || i think that we shouldnt have messed with the ecosystem to begin
 * Green338 || I suggest that we make an animla preserve to keep the alien spieces captive ||  ||
 * Green347 || i suggest that we should research into these species alittle more and figure out a way that will help us stop this species from killing off other animals. ||  ||
