Restricting Introduced Species

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.

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.

Most of the time people bring non-native species into new environment by purpose. The people who bring them to their new environments mostly aren’t aware that they could harm their new surroundings. When trying to reverse the effects of an invasive species it could take years. It takes volunteers hours upon hours to dig up plants, trap, scare away, burn, poison, and animal proof areas to prevent an invasive species from spreading. Introducing a non-native species into a new environment is like introducing fire to

Invasive species are very common all over the world. Invasive species are an organism that lives in an ecosystem in which they don’t belong. Invasive species are not only dangerous to people, but also the ecosystem and must be removed.

An example of a harmful invasive species is the Asian Long-Horned Beetle. According to the United States Department of Agriculture, an Asian Long-Horned Beetle destroys “millions of acres of America's treasured hardwoods, including national forests and backyard trees.” When the trees are killed, the environment is damaged. According to the Center for Invasive Species Research, “if this pest enters a forest ecosystem, the economic impact could be far greater than eradication and containment costs and could adversely impact export markets for various hardwood products such as veneers.” The insect negatively influences the economy, for it demolishes valued trees that are used to create certain products that need forest resources in order to be created.

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

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.

An invasive species is a species that comes out of its natural environment, and enters another. These animals are usually very bad for the ecosystem and may cause an unbalance. These animals usually come in with many competitive advantages and can easily dominate any competition. This will give them the ability to eat as much as they would like without being threatened in any way. This could possibly diminish many populations and end an entire ecosystem.

Humans are the reason why we’re dealing with invasive species, and why we should fix this problem. Imagine being an owner of Burmese python. You obviously adore the little guy---well, not so little---but your parents don’t. And from their kindness of their heart, they release your python into the wild instead of killing it. And the place they released your python is the Everglades, which many others did exactly what your parents did. But the thing is, that was a really bad idea. This Burmese python could cause---and probably already has---a lot of harm. These are some threats they could commit: 1) Praying on native species, 2) Out-competing native species for food or other resources, 3) Preventing native species from reproducing or killing

Our invasive and native species impact our eco systems dramatically. Although they seem to be harmless from rapid breeding and overpopulation. Taking over the surrounding areas so that other species are not able to survive. Aggressive species is another way to impact the ecosystems by endangering other species that live in the same habitat.

Invasive species are those that normally live and thrive in a particular community. Non-Native species lives outside of its native range which has arrived there by human activity.

The biodiversity effects of non-native invasive species have been described as “immense, insidious and usually irreversible” (Veitch and Clout, 2002). There is significant evidence proving that invasive species can cause severe economic, environmental and ecological damage (Mack et al., 2000). A lot of time and research has been devoted to dividing the world into regions with distinctive habitats and species. Numerous pathways, mostly anthropogenic, are breaking down these realms and facilitating the ecological and biological invasion of non-native species.

In most cases, it is difficult to relocate an invasive species, so there must be a different method to prevent the species from damaging their new ecosystems. By the time the damage is done, it is often too late to reverse the damage and stop the spread of the invasive species. However, there may be a way to cease the harm caused by invasive species using genetic modification.

Franck and Brownstone define biological diversity as 'the variety and variability of living organisms and the biological communities in which they live' (36). Decades of progress in both the scientific and political arenas have advanced environmental legislation to protect biodiversity at not only the ecosystem level, but for specific species and genetic material as well. Research has shown the importance of every organism and their role in the global ecosystem, and legislation has gradually matured to protect not only species which may become endangered, but the habitats they need to survive as well. Growing consciousness surrounding environmental issues has enabled these protections to be
