Also, the introduction of new plant life causes confusion among animals as to what the unrecognizable species is. In some cases, the invasive plant harms existing animals or plants in the ecosystem and may cause death. Ultimately, invasive species result in overpopulation and issues concerning the food chain.
These habitat and species modifications could create an irreversible shift in the ecosystem, creating an altered, stable state. While invasive species cause damage in many ways, one of an invasive specie’s most devastating effects is habitat modification. Once a habitat is physically altered, even if the invader is removed, it becomes difficult or impossible to reverse the effects. In Life Out of Bounds, author Chris Bright describes the cycle of degradation (1998). As local creatures disappear, the loss weakens the strength of their ecosystem.
The outbreak of such disease can lead to significant economic losses, both in the form of loss of production through the large scale extermination of infected animals, and through cost associated with adverse health effects in humans. Therefore there is large interest in finding solutions to these problems. One such solution has been the use of antibiotics in farm animals. While this has reduced the risk of certain diseases, over the years of use this has led to the rise of many antibiotic resistant micro-organisms, who pose a great risk to human health on their own. With the advent of genetic engineering technologies it has become possible to create new livestock animals whom are less susceptible to certain disease or might not transmit such diseases to humans (Houdebine 2009; Laible 2009).
If the land looked wild it needed tamed to their ideas, even if this made the ecosystem unstable or less productive. The results of their need for control and their lack of knowledge on ecosystems resulted in a reflux of new plants being imported. The most influential plants were the forage or grazing crops. These were brought because the Europeans wanted their own familiar crops to be in the grazing yards. These plants included white clover and "Kentucky" bluegrass.
Non-native species is a term commonly used to refer to plants and animals introduced to a foreign environment mostly by humanity either intentionally or accidentally.. Such exotic invaders die because they cannot adjust to the introduced ecosystem, which implies they entail domestication. However, some thrive to the extent of dominating their new ecosystem by spreading quickly and widely. These kinds of invaders do not have their native predators and with time take over the ecosystem from native species (David and Sweeney 53). The term invasive can refer to introduced species and diseases as well.

The activists are the reason that there are laws in place right now to protect animals and their rights. Some of the policies that have been passed and out into place are based on the Animal Welfare Act and Wildlife Transportation, Hunting. An article written by Hobbs, Isaac, Hobbs, and Kerr addresses the topic of domestic food policy and trade laws. The article explains that the laws put on trade and domestic foods are a result of the increase in animal welfare standards and is put in place to inform the public.
Diamond (2002) defines a domesticate as “a species bred in captivity and thereby modified from its wild ancestors in many ways making it more useful to humans.” He goes on to explain the shared characteristics of domesticated animals, which include decreased brain size and sensory organs that were less fine-tuned, and plants – stalks that are preven... ... middle of paper ... ...companions or the potential to use maize as an alternative fuel, the negative consequences of domestication have become increasingly greater. All of the negative outcomes that have arisen from the exploitation of domesticated species began as an effort to improve human health and well-being. The products of this over-domestication are startling and have come full-circle to being a cause of exactly what they were meant to remedy. Domestication is not final until the traits that confer it have been genetically integrated into the new species and often these traits are not reversible. This means that the further evolution of domesticated species under the artificial selection of humans will continue to lead to health problems for all of the living organisms involved—from those as small as microbes to the humans that serve as the guiding force—and environmental decline.
The Environmental Impact of Human Exploration Throughout history, there has continually been movement - of peoples and cultures, diseases, and technology. The movement of each type has affected the environment in different ways. The effect of the changing patterns of human movement on the environment is leading to further environmental degradation. The history of human movement has been one of a shift from a nomadic lifestyle to a more sedentary one with the agricultural revolution. With the agricultural revolution, people gradually abandoned the hunter-gatherer lifestyle, so they were no longer moving around, following the migration patterns of the animals that humans hunted and the seasonal pattern of plants as they became suitable for consumption (Discovery Channel 01.27.04).
We as people are some of many reasons animals become endangered. Natural habitats are ruined because of human activities such as construction work, the extension of agricultural work, destruction of forests, etc. which results in bad effects in animal’s habitat, food cycle, reproduction progress and climate. They don’t have any further vegetation which causes them to Land for cultivation is extended due to the population growth. Various types of development and construction work are continuing.
Accepting the doctrine of Animal Rights can result in the extinction of native animals, and also cause adverse effects on the environment. Another consequence of accepting the doctrine of Animal Rights is that humans will no longer be able to control foreign predators (pests) via traps, hunting, fishing and poisons. Many foreign animals have been introduced to different ecosystems over the course of history, and is very likely to have caused many extinctions of indigenous species. This occurs because they compete with native animals for habitat and food, and sometimes introduce new diseases. Maintaining the indigenous species and thus biodiversity is important because animals depend on each other in a food web, and an extinction in one can result in many more following.
