Out of all the problems our environment faces like pollution and global warming, one of the most threatening problems is invasive species. An invasive species is an organism that is not native to an ecosystem and causes harm. They can harm the environment, economy, and even human health. When an invasive species starts to affect the economy, it becomes a bigger problem because it starts to get expensive to maintain and control.
An article states, “If they do manage to survive in the wild, domesticated animals take resources from native species,” (Pesky Pets, paragraph 4). This exemplifies the damage that invasive species cause to native plants and animals. An invasive plant could poison native animals, which would unbalance the ecosystem. Some may believe that if humans step in they will cause even more unbalance. However, this is not a credible statement because those people are not taking account of the amount of disturbance that will occur if we don’t do anything. The amount of damage will be miniscule to the amount of damage that would be upon the ecosystem if nothing is done. Therefore, humans must take action before any harm falls upon the native plants and
With the environment, as one of the most commonly discussed topics today, invasive species are often included in these discussions. However, many seem to participate in these conversations with limited background on the topic. It seems that non-native species are unfairly given the title of ‘invasive’ for a variety of reasons which I plan to explore. As a starting point, it is important to understand the various titles that are allocated to non-native species that have been introduced into a new ecosystem. Under the umbrella of non-native species, there are multiple classifications given to wildlife found in a region different from where the species originates. The broadest of these classifications is non-native or exotic. Non-native is very much a cut and dried description; the species is found in an area that it is not native to. Beyond non-native is established exotic. A species can be distinguished as established exotic if it is first considered a non-native species, then can establish a breeding population. In short, this means that the species must not only be new to an environment, but can then survive and succeed as a species in that environment. Last, there is invasive. To be considered an invasive species, the species must fit three criteria: one, the species is not native to the environment it is found in. Two, the species has been able to reproduce and has created a viable breeding population in the new environment. And finally, the species has begun to cause
The world is under attack; by aliens from our own planet. These aliens are known as invasive species. Government agencies such as the Environmental Protection Agency (EPA) and the Department of Natural Resources (DNR) have identified invasive species as living organisms that are not native to an ecosystem and their introduction can cause harm to the environment, infrastructure, and people. When these creatures are in their natural ecosystem they can be held in check by predators and other organisms that have evolved to deal with them. Without these opponents invasive species can and will cause economic and biological damage to the area they are introduced to. Invasive species can affect anyone and anything and they must
The introduction of foreign or “invasive” species into ecosystems places a massive risk of exposing the inhabitants of this environment to mass extinction, far lower rates of biodiversity and potentially irreversible, permanent changes to the biological makeup of the food web. The ethical problem involved with this serious situation is whether the culling or “selective slaughter” of these invasive species is ethical, if, in doing so will inflict pain and suffering. To come to the morally permissible answer to this dilemma one needs to come to a conclusion of the legitimacy of animal’s pain and suffering and thus how heavily it plays a role in coming to an ethically strong conclusion. Through the exploration of the specific case of the introduction
There are a large number of species that have become, in some way, introduced to areas outside of their native ranges. Some of these species have large ecological impacts and can even cause economic problems or harm to people. Other species, however, are less obviously problematic. Attempting to eradicate even a single invasive species is generally a highly expensive process that can take a very long period of time. Although one can instead choose to simply suppress a species instead of entirely eradicating it, even this can take considerable time, money, and energy. Consequently, only invasive species that clearly cause large problems should be targeted while those that do not seem to be harmful should be more or less left alone in order to
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
At the Fort Snelling State park, there are several aquatic and terrestrial invasive species. We need to eliminate and reduce their reproduction as soon as possible. By the way, what do we mean by invasive species? They are plants and animals that are not native to Minnesota. Zebra mussels, new species of Silver Carp, and Eurasian Watermilfoil as typical examples of invasive species in the park, which make headache in Mississippi and Minnesota River. 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. However, these invasive species are accidentally
A steward is someone who manages someone else’s property, possessions, or financial affairs. We have the responsibility to be good stewards of God’s earth. All creation has a place and an order made by God, and we should keep it that way. This includes keeping invasive and exotic species from causing other species to go extinct. As a Christian, one of the easiest things I can do to help stop the spread of invasive species is pray. I can pray for the people that are figuring out ways to stop it. I can pray that others would help in the fight against invasive species. And I most definitely can pray that the invasive species would just stop spreading. As Christians, God told us to rule over every living creature. That means that it’s our job to
All of our Earth 's ecosystems are fragile. The transfer of energy and the interactions within them are kept in frail balance by nature, similar to a tightrope walker balancing themself at a height of a few hundred metres. What would happen if that tightrope walker lost his balance and fell? Similarly, what would happen if a species arrives at a foreign ecosystem? If a non-native species negatively affects its environment, then it is considered an invasive, or alien, species. The human society is in crisis. Invasive species cause the damage of the native environment. They are one of the causes for the decline in the human economy. The invasive species also negatively hinder our health. This phenomenon is occurring in a global scale, impacting Lake Victoria in Africa to the Oak Ridges Moraine in Canada. People are trying to use different techniques to control the introduction of invasive species and negate their impact on the native environment. Invasive species are a threat to their foreign environment and should be prevented from causing further damage.
The introduction of an invasive species can change the organization and functioning of the native communities through various processes such as predation, parasite transfer or competitive exclusion. The two main explanations why some exotic species become invasive species are superiority in competition and the opportunistic use of ecological niches generated by human activities. (Nishizawa). Invasive species contributed to the decline of 42% of the threatened and endangered species in the United States. Not only that, invasive species’ impact is about five percent of the world’s economy. (Pimentel et al. 2005). For example, we were conducting an experiment with an invasive species called Elephant Ears. Elephant ears can be invasive
One of the most unrecognized threats of Colorado is invasive species. Invasive species is a type of species that is not native. Commonly invasive species have no predators. With no predators an invasive species can populate fast, and have a huge population. An example of an invasive species is a Northern Pike. Originally from Northwestern Europe across northern Asia. The Northern Pike was first introduced to North America in 1874 as a game fish. Invasive species such as the Northern Pike can be really harmful to the environment. Do to the Northern Pike not having any predators it can kill without being hunted. This can lead to very dangerous things. One dangerous thing is the food chain. When there is a species that kills other species,
What makes an Invasive species able to take advantage of new environment for one is the lack of predators or parasites in the area, which helps to keep the population from dying. Invasive species also multiply in an alarming rate and have a total impact on their environment and other organisms. Invasive species can affect the ecosystem function, also the economic value, human health, and they can alter ecological relationships among the other species in the area. These invasions may also reduce the ecosystem’s biodiversity and cause harm to individuals who depend on those biological resources. However, invasive species can replace the native ones over time, by extinction of many native
In short, alien species’ bad reputation, while justified in some cases, is unwarranted for the majority of organisms. Many different kinds of species have been spread all over the globe due to human activity, and one result of this is that many native species have been negatively impacted by these invaders. Consequently, in an attempt to solve this problem, the United States spends over $120 billion tax dollars every year in control efforts trying to prevent the spread of foreign species, with few apparent results. This, however, is not the answer. Out of all non-native species traveling the globe, the number of harmful species is very low. Even if such migration restrictions were effective, the low percentage of invasive species would be kept
This project is a partnership between the University of Oregon’s Environmental Leadership Program and the management at Newberry National Volcanic Monument (NNVM) in the Deschutes National Forest. Our team, a group of 11 undergraduate students, collected data on invasive species at NNVM in September and October of 2017. Our survey routes were based on a map produced by the United States Forest Service (USFS) that outlined the previously recorded locations of invasive species at NNVM. The USFS map was a composite of several data sources and was the best available information prior to our survey. Our team used this map to evaluate previously recorded populations and to look for new or unknown populations. Our evaluations included updating
