Did you know it only takes one spawn of an invasive plant species to take over the whole plant.(Invasive plant).1 this paper will talk about the controversial issue known as invasive plant species , the cause of it and ways normal everyday people like you and I can prevent this environmental issue known as invasive plant species. One of the very many of the species is the Russian Olive, the Russian olive originated from Eurasia. It was introduced to the central and western us by the early 1900’s. The Russian olive can impact thousands of native species. The scientific name of the plant is Elaeagnus Augustinian L. (Plants) ,pg 2. Another species is called the English ivy. The arrival of the English ivy dates all the way back to the early 1700’s …show more content…
These plants are taking over everywhere, for instance here in southern Illinois we have an invasive plant species known as the Russian olive. The Russian olive is a plant that crowds out all native species surrounding it. Ways we an effect it would be to find the the plant and cut it out before it can spread even more, one any way of removing the roots or killing the roots would be exterminating the plant's presence. Other ways of removal would be to burn the ground it is on, to do this you must first make sure the ground is dry enough to burn and also make sure you have a water source around you in case if accidental. If the fire happens and you did not locate your water source call your local fire …show more content…
These plants are capable and have more than enough potential to wipe out an entire regular native species of plant (invasive plants). The reason behind this is because one small offspring can rapidly reproduce causing it to do the damage. The people who are doing this are the ones who will plant them or plant other greeneries near the non-native plant species. The invasive plant species are very rapid in growing. Some of the birds, winds, storm, and environment user help contribute spreading the invading species around or close enough to execute the other plants. Although sometimes the birds and so on can help get rid of the specific Invasive plant species have contributed to the decline of 42% f United States endangered and threatened species, and for 18% of United States endangered or threatened species, invasive are the main cause of their decline. Some other impacts are Invasive species compete directly with native species for moisture, sunlight, nutrients, and space. Overall plant diversity can be decreased, establishment and spread of invasive species can degrade wildlife habitat,results in poor quality agricultural lands, degraded water quality, increased soil erosion, and decreased recreation opportunities.

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).

When people think of invasive species, they normally do not think of the human species, but why not? There is a large debate about whether or not humans are an invasive species. Before people debate whether or not the human race is an invasive species, they should know the definition of one. The legal definition of an invasive species in the United States is “an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health” (Zielinski). The International Union for Conservation of Nature, IUCN, defines an invasive species as “animals, plants or other organisms introduced by man into places outside their natural range of distribution, where they become established and disperse, generating a negative impact on the local ecosystem and species” (Zielinski).

Contrary to popular opinion, illegal immigrants do not contribute to the U.S. economy. Instead they cost more by using government provided services, taking jobs from native workers, and reducing wages by competition with native workers. Proudly a nation of immigrants the United States attracts people from all over the world because we are a nation of laws. (Demint) For centuries immigration has been indispensable to the health of our nation, as it will be for our nation’s future success. (Demint) Although this is true, immigrants should still come to our nation lawfully and not burden our nations loyal and already overburdened taxpayers more with fiscal costs. (Demint) Foreign born people residing in the United States at the time of a population survey who were not U.S. citizens at birth in 2012 were reported to be 4.2% born in Africa, 29.2% born in Asia, 11.8% born in Europe, 52.2% born in Latin America including South America, Central America, Mexico, and the Caribbean, 2.0% born in Northern America including Canada, Bermuda, Greenland, St. Pierre, and Miquelon. (Migration) The top three countries from which illegal immigrants were reported to have been originally born in are Mexico, India, and China. (Migration) With illegal immigration becoming more common by the years you can only imagine how much those numbers have increased. Having illegal immigrants in the U.S. and how to deal with the productive and government fee-conflicting immigrants can cause much controversy on whether they hurt or help our economy. Pardoning the offense against our government to those who break the law and putting them on a path to become citizens of our law-based nation would be unfair; also it would just impose more unacceptable behavior and major...
Modern-day genetic technology has granted mankind with the opportunity to bring back extinct species from the dead. If humans have come to possess the DNA from an extinct animal population, it is possible to create an identical clone of the animal in question, effectively “bringing it back from the dead”. Many ethical dilemmas surround the practice of de-extinction, and rightfully so. Recreating an extinct species could produce groundbreaking scientific breakthroughs, generating exciting opportunities for future genetics-based research. However, there could also be monumental consequences: the newly revived, once-extinct species might destroy the ecological equilibrium of modern Earth
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.
The relationships between plants and pollinators play a key role in our ecosystems. Pollinators are animals, such as bees, butterflies, moths, bats, flies, wasps, and birds, that transfer pollen from one flower to another. Pollination is the movement of pollen to the male or female part of the plant. This leads to fertilization and the production of seeds and flowers. They maintain and establish ecosystems. “Pollinators are an integral part of our environment and our agricultural systems; they are important in 35% of global crop production” (NCRS 2013). “Pollinator declines can result in loss of pollination services which have important negative ecological and economic impacts that could significantly affect the maintenance of wild plant diversity,

Have you ever thought of why people commit illegal immigration? Even though they know very well that once they are caught, they would be sent to detention faculty and then get sent back to the place they escaped from. I bet you haven’t even given it the slightest thought. I bet all you care about is the word “law.” Law is a system made by people that people use to uphold justice and fairness on people who committed a crime. Laws is not perfect. What we seek in our life is not a law that is imperfect, what we seek is the truth behind the word “why”. The truth behind the question, “Why did they do it?”. In illegal immigration, the answer to the question is that they seek a better life.
In our world today we have approximately 26,021 endangered species. Endangered species are organisms that may possible become extinct. The term 'endangered species' refers to all species that fits this description. However some conservation biologists and scientists normally use the term ‘endangered species’ to refer to species that are put on the IUCN(International Union for Conservation of Nature)Red List. Many factors can be looked at when considering the conservation status of a species. Factors such as human threats or environmental threats can cause a species to become endangered.
Home gardens offer a wide variety of benefits to the environment and serve a diverse group of people. Home gardening provides a source of fresh produce and free of chemicals, it also gives you complete control over the chemicals and products used during the growing process. A home garden allows you to pick the produce when its ripe, unlike produce at the store is often picked before its fully ripe. The quality and flavor of the freshly picked produce from home is better than the produce that might have unknown chemicals and was likely picked several days or weeks before being sold. The produce retains more nutrients when consumed shortly after being picked, making your home garden vegetables a healthier option. A garden also provides a positive environmental impact. The compost allows you to recycle certain kitchen and yard waste into a nutrient-rich additive for the garden. This provides natural fertilizer for you plants and reduces the wastes you produce. If you choose to avoid or limit chemical use, you reduce pollution from your gardening activities. Besides being good for the environment gardens have environmental gains for us. Gardening help control urban temperatures, If the environmental landscape design is effective it can cool your home in summer and warm it in winter, it can also reduce the energy cost by up to 20%. Gardening, and all the physical activity that goes along with it, leads to a better overall physical health, weight loss, improve you bones, and reduces the risk of having osteoporosis. “In a study of 3,310 older women, researchers from the University of Arkansas found that women involved in yard work and other types of gardening exercises had lower rates of osteoporosis than joggers, swimmers, and women wh...
