Imagine that you went to Australia. While you are there, you see a European baby bunny, what would you think?, Awwww, so cute, adorable, and you would try to pet it, little do you know that that was invasive species. An invasive species is… “An organism that is not from around the place and is causing damage, usually connected to native or naturalized species.” says John Odenkirk, helping Florida get rid of the Northern snakehead, a invasive species. They don’t have any natural predators,so nothing eats them. Therefore, they growth goes unchecked. A european bunny is an invasive species in Australia. “They destroy Australia's trees, eat the food of their native animals, and cause soil erosion.” says Zoologist,Joanna Bagniewska There …show more content…
⅕ of all extinct animal are due solely to invasive species. European Environment Agency estimates that the economic losses caused by biological invasions amount to 12 billion euro (2,487,740,000 dollars) EACH YEAR!! “They may be bigger and more aggressive than local species, so they take a larger share of any available food.” Some can also affect humans. They can harm other animals, which humans need to survive. Mosquitoes can carry viruses, such as the West Nile virus, that infect people. Some of the snails carry a parasite that can cause meningitis (an infectious disease) in humans. Nutria is a furry rodents, ranchers brought from South America in the 1930s to raise them for their fur and because they looked harmless, but they damage crop areas along U.S. coastlines. Back Home You may wonder if we are ever going to get rid of this animals, but don’t worry,the Branches of Government are helping, and so can you. Laws have stopped people from selling exoctic pets or fine people who let their pets into the wild. For animals who already invaded, captured and moved them back to their original homes. You can help stop before they establish, by finding invasive species and calling an invasive species
Invasive species as a whole have become a nuisance to many habitats and ecosystems around the world. What defines an invasive species is the following. It must be a species that is foreign to the habitat it resides in, have no natural predators which allow it to reproduce in such a rapid manner, and out compete native animals of food and shelter (Rosenthal 2011). These characteristics are what create such high populations of these invasive species in various habitats around the globe.
The piece I chose to do my literary analysis on was the article, The Truth About Invasive Species, written by Alan Burdick. The article states that invasive species are all around us, but the area with the most prominent amount is the suburbs of Miami. It goes into detail about how abundant invasive species are in this area. Most people who would see a strange animal in their lawn or area would be bemused, however for the people of Southern Florida, this is a recurring scene. Burdick states that “virtually everyone in the South Florida, including Hardwick, has a neighbor with a backyard menagerie of lucrative critters on hold for resale”. Burdick describes both how an invasive species is introduced into an ecosystem, and the impact the have on other species upon their arrival.
Invasive species are non-native organisms that occupy habitats and disrupt the natural ecological cycles of the habitat. They threaten the biodiversity of an ecosystem and are biological pollutants Invasive species introduced into new habitats usually maximize their reproduction in their new home and crowd out native species. Their lack of natural predators in their new community allow for a proliferation in growth and expansion as a result of their abundant food supply. Once they are established, invasive species can rarely be eliminated because their new habitat is favorable for their survival.
Nonnative species can also be called alien, exotic, or nonindigenous. Their presence is due to humans dispersing them to other locations beside their native habitat, or by humans creating environmental conditions that allow their growth. When nonnative species begin to take over a new habitat and displace native species, they are then termed an invasive species. Nonnative invasive species are one of the biggest threats to ecosystems in North America (Cox, 1999) because they are able to have an impact on many levels, including ecosystems, communities, and populations (Cushman, Tierney, & Hinds, 2004).
Invasive species are organisms that harm a new environment that they are not native to. Many invasive species like Eurasian milfoil are easily able to reproduce and can do so fast. Due to this, the limited space in a body of water or area of land is quickly taken over by the invasive species so other native plants face the risk of death or even extinction. Overall, these invasive species can do great harm to an ecosystem or an economy, causing problems that are destructive to numerous organisms.
Did you know that you happen to be surrounded by invasive species? These species are animals that come into areas they do not belong in. The articles, “Invaders among Us,” and “Invader Alert,” show this. They harm the environment, cost tons of money in damage and extermination, and they have to be prevented.
Felis catus the domestic cat, an introduced species as a direct result of the human population is responsible for 26% of the extinction of the total population of Birds, mammals, and reptiles worldwide. This has severe implications and a threat to Australian Biodiversity. The major impact suffered as a result of the Felis catus on Australian Biodiversity is the decline and in some cases extinction of mammals. Predation being responsible for the impact on
Slowly, the disruption of these delicate balances are taking their toll on the native habitats and transforming small temporary changes into permanent problems. The area of environmental modification that will be emphasized in this paper is the introduction of non-native species to new habitats and the resulting effects on that habitat; specifically, the introduction of the European Rabbit to Australia.
Invasive species only started to show up in the United States when the Europeans started to arrive. Beforehand, very limited contact was made in this particular region of the world, so very few invasive species came into North America. When the Europeans arrived in 1492, after Columbus discovered North America, they brought their own culture and essential food and animals with them. At first, it was just the basics of maize, wheat, pumpkins, and squash, but later on it also included cows, chickens, and horses . As more Europeans flocked into the country, non-native species began to appear in the area. Often, as non-native species appeared it led to unintended consequences of destroying gra...
Invasive species are everywhere around the U.S and other places. These plants and animals were introduced to a new environment by unnatural means, often by human activity. These invasive species could harm the ecosystem, destroy other wildlife, and alter the environment. What could be done to end this problem? Should humans take actions to reduce invasive species?
Invasive species, (also known as invasive alien species or simply alien species) are defined as any organism (plant, animal, pathogen, or other living thing) that is alien (non-native) to an ecosystem, which can cause adverse economical, ecological, or health effects to native species and/or humans. The roots of these problems all stem from the massive negative ecological impact these organisms are having on the environment (CBD, 2009). For all animal extinctions where the cause is known since the 1600’s, invasive alien species have been a contributing factor 40% of the time (CBD, 2006); the second most contributing factor to extinctions after loss of habitat (GC, 2013). By eliminating native species through competition for resources, predation, and transmittal of disease, invasive species continue to reduce biodiversity in almost all ecosystems around the world (CBD, 2009). In the future, this problem may worsen, and if no action is taken, could lead to a cascading ecological problem so large that whole communities or even ecosystems could collapse.
One of the big causes of extinction or the endangerment of species is foreign species entering a habitat. This species that are not native to the land can disrupt the food web in that community. These species take control of the food web and endanger some of the other species. The native species become endangered and over the course of many years they either adapt to their new way or life, the foreign predator leaves or is killed off due to the different environment, or the species is killed off and becomes extinct. Organizations like the “World Wild Li...
Have you ever had a exotic pet? Do you think that you could take care of a wild animal? Do you think that anyone can? Why would you have an exotic animal in the first place? I believe that you should not let citizens be allowed to keep or own a exotic animal as a pet?
Owning an exotic animal as a pet has been a dream for many people from various societies around the world, while in the gulf that dream has become a reality for some individuals. Hanan Al-Sarraf an animals rights activist residing in Kuwait states that acquiring exotic animals has been easier than buying a cupcake. Due to the availability to buy these illegal animals on the internet publicly, and even on social media one example would be Instagram vice news (2015). Stricter animal laws on owning exotic animals should be implemented in the Gulf States.
Our planet is suffering from severe pollution, which ranges from contaminated air, water and soil as well. Humans are doing nothing to reduce the amount of pollution that is harming our earth. To understand how pollution works first you must understand that there are different types of pollution. The most common types of pollution and the ones that I will be focusing on which are the ones doing the most harm to our planet are air pollution, water pollution, soil contamination and littering. In order to help out and reduce pollution in our planet people need to be more aware of what these problems are and about the severe damages that they are causing our planet. Before industrialization really jumped into place and had an effect on large cities, nature had its own way of cleaning up its own air and itself. Wind scattered gases, rain washed many substances and the rest dissolved into the ground; while plants absorbed carbon dioxide and made it into oxygen. With big cities growing more every time and with more towns that were becoming more industrialized a lot of more waste began to be released into the environment and the atmosphere and soon this was more than enough for nature to handle. In order to stop and reduce pollution people need to understand the damage that it is causing our environment and our planet as well. People need to be more aware of how they can help out and do their part in reducing these problems that are causing our planet to die slowly with people not even noticing it.
