What governments should consider before transferring species. You’re on a visit to your childhood town following one of your favorite trails in the mountain when you notice something peculiar, all the trees are dead. This what happens when the government and major companies don’t consider everything that could happen when bringing foreign species into different lands. Before the transfer of species the diet, affects, and benefits of the species must be considered in order for there to be no casualties and still be able to benefit.
First, diet, weather on purpose or not non indigenous species can harm the environment. When the Balsam Woolly Adelgids were accidentally imported from Europe to the United States, they fed, killing thousands of Balsam Fir trees. Leaving many once rich forests, dead. All of which could have been easily prevented with proper checks of the cargo and/or research done on what they would eat in the foreign land.

Take Cane toads for example, they were brought to Australia to amend- a sugar eating bug problem, but with no other research done to figure out what they could do, things went wrong. They ate all the other bugs in the farm and multiplied like crazy, having no predators evolved in such a manner to combat the toads poison in this part of the world, it took over and killed many thousands of animals. Even pushing someone towards extinction. Had the scientists in charge done more research or gathered the small amount of toads in the beginning once the project failed, it could have been
Extinction: Most species become extinct because they can’t cope with the environmental change, and also because of introduced species that turned into competitors for
Invasive species make bad situations into worse situations. Having a species from a different ecosystem makes them invasive species. Such as a toad or even bacteria being in another ecosystem other than their natural habitat.
An example of an invasive species is “Cane Toad.” The cane toad was supposed to get rid of sugar cane pest, but then it came a pest. It only has a few predators outside from where it lives.But when animals try to eat it a discharge of poison goes on it’s skin and the predator gets poisoned and dies in a few minutes.Also it has been released into out of zoos on purpose.The cane toad used to live in South America and mainland middle of America, now it has been moved to Oceania and the Caribbean also North Australia.What people do is they eat toad and make soup of their eggs but this ends up killing them.
In the two previous examples it is possible that these species were introduced accidentally. There have been cases when an invasive species is introduced in order to terminate another invasive species. The issue with this is that they will often times feed on everything they find. Kolbert supports this idea by discussing introduction of the wolfsnail from Central America to Hawaii. The wolfsnail was introduced to the Hawaiian environment to prey on the giant African snail that had turned into a pest for agriculture.
Until a stable balance is reached, healthy and balanced ecosystem keep this balance through several limiting factors, which can restrict and regulate the size or range of species such as natural climate, geography, presence or absence of predators. When, however, these invasive species are accidentally or intentionally transplanted into out waters. They can upset the ecological balance. They lack disease and predator controls, so these non-native species can rapidly reproduce and spread at an amazing and faster pace than native species. The consequence is that these invasive species compete with native species for food and habitat. These organisms harmful not because of what they are, but where they happen to be. Most of the world’s ecosystem are the result of coevolution by numerous different organisms in the worlds, adapting to their environment and each other. In other words, natural ecosystems become totally disrupt and out of balance. if the new species and habitat’s limiting factors fail to restrict the rapid
A species that is introduced to an ecosystem by humans can harm ecosystems in many ways. Animals that are introduced into a new area, could hunt a main food source for some animals, causing that population to decrease. Plants could be poisonous, or need to feed off of other plants. Species introduced into an ecosystem by humans through off the natural balance of the wildlife.
In today’s world, hardly any species of wildlife become extinct from natural causes. Europeans hunt animals to such an extent that we classify it as overhunting. We destroy their habitat, and introduce other animals that are a threat to endangered animals or are competition for resources and food. Habitat destruction is the greatest threat to both animals and plants.
Claim: Pollution could affect wildlife like fish, birds, and others by hurting or killing them due to trash or litter stuck in weeds or floating above the water in the air.
Every day we shape the very environment we live as human beings but by far one of the most destruction mistakes was the introduction of invasive species. Enviroments can be destroyed if one species gets wiped out and as recipients of this, we have not realized the very way we are destroying the earth. But one animal that I believe is causing some the worst destruction to environments is the Eurasian Wild Boar.
One example is what humans did to the siberian tiger population. If humans hadn’t been killing it for fur, wine, and all of that other junk that they don’t need, there would be more than 4,000 of them today. The siberian tigers are also a main predator in the biome,
If science has taught us anything, it is that one event invariably effects countless others. This is no more evident than when a species is introduced into a new environment. Once a foreign species finds itself in new surroundings, it can either die or adapt. Often, these introduced species take over the environment, irrevocably changing it to fit their needs. This usually leads to a serious deteriorating in the well being of species currently existing there. Such is the case as when the Europeans introduced themselves to the New World. The new arrivals not only brought themselves, their technologies, and ways of life, but, most disastrously, their diseases arrived as well.
Introduced species can also wreak havoc by being defensive predators themselves. They can bring toxins and poisons into the ecosystem that their prey and predators alike can’t combat. “The [cane] toads are toxic, and native predators have no immunity to the poison,” (Semmler, para. 5). This makes them a keystone species (a species that has an impact with a size that doesn’t correlate to its population size). They affect large amounts of the ecosystem and food web, even while not having as large a population as other species that are
Influence on ecosystems range from human causes like the bulldozing of a forest to natural causes like a fire or a flood. In recent times, the introduction and spread of invasive species has transformed native communities rapidly and, in some cases, created irreversible damages. In the Earth’s history, changes have often occurred in the ecosystems. For example, glaciers and the retreat of glaciers cause wide-spread changes. However, although change is a constant in ecosystems, animals and habitats often cannot adapt to the rapid alterations of non-natural stresses. Harm to the environment from the introduction of invasive species occurs through changes in the habitat and declines in the native species. Invasive species
It is no question that invasive species cause more damage than nourishment. They have caused harm on every continent on this planet and are a threat to their ecosystems. The key to successfully managing invasive species is to understand what they are, how they arrive here, and the damage they cause. That way we as a society can recognize the threat that they pose to our ecosystems and manage them. Step one in successfully managing invasive species is to understand what they are.
Could the Endangered Species Act itself become endangered with the current debates? Recently, many conservation advocates and government officials think so, pointing to the proposed policy change that could make it harder for wildlife to receive protection under the Act. So, what does the future hold for the Endangered Species Act? With more than 40 years since the passage of the ESA in 1973, politicians and environmentalists alike have analyzed the realities of the Act, creating an interesting current state of debate regarding conservation. With poor administration and provisions designed to promote good science and good sense flouted, the Act needs to change and improve to find the best middle available between the suppression of economic activity and the preservation of species within the United States. The Act now more than ever is in need of political cooperation that can both revive and reform it to best protect against future challenges and obstacles otherwise the act will eventually be rendered useless due to it ineffectiveness, falsified science, and lack of consistency.
