When a person hears the word invasive species they immediately think the negative aspects of the plant. How invasive species are a threat to all native plant and animal species making them threatened or endangered. With that being said the Invasive plant species need to be controlled in order to reduce the number of the invaders and let the native species thrive but have you heard of the fact that some aspects oven bases are beneficial. If there are beneficial aspects to the invasive species then why are the invasive species so brutally frowned upon by society? In other words Kenny’s invasive species and general have a positive effect I’m an ecosystem instead of all the negative impacts and information about them based on research. Is there any positives that come out of the ecosystems when invasive are a part of these environments. First of all the definition of an invasive species is that it is a species that does not from the area is found or located in. This means that the plant species originated from somewhere other than where the species is currently located. Most of the bases species plants have been very unique and have originated from Europe in Asia and have migrated over to the United States in North America. They have become an environmental problem …show more content…

The state of New York is attempting to control these invasive species such as purple loosestrife and water chestnut that have popped up throughout this state.

The introduction of non-native species, like lawn grasses and trees planted by developers, can alter the landscape and encroach into the surrounding wilderness. As McPhee notes, development also triggers the spread of less desirable plants such as poison ivy, which are otherwise absent from the Pine Barrens. Next are the endemic species in the Pinelands-- the flowers, mosses, birds, fish, frogs, and snakes that are either entirely unique to the region or are only found halfway across the world. Because of their limited distribution, development that endangers the habitat, migration, or nutrient access of these species could quickly lead to extinction. With pressure from development on top of the effects of climate change, there is a notable threat to the biological diversity and ecological resilience of the Pine

In other words, when new animals were introduced to Europe, nothing happened to the environment. This was a positive effect for Europe seeing how they were only benefiting from the introducing of new animals. The Americas however, had a different reaction. The introduction of new animals caused a negative impact on their environment. It caused overgrazing, which is when farmers allow for grasslands to be grazed so heavily that the vegetation is damaged and the ground becomes liable to erosion.

“ The non native tortoises are eating the fruit produced by the ebony trees and dispersing their seed all over the island. Over a decade after the Aldabra tortoises were introduced researchers are nothing that the endangered ebony forests are beginning to recover” (J. Francis Wolfe). This shows and proves that the invasive species Aldabra tortoises are helping grow back the ebony trees. Also in the text it states, “ Not only do the tortoises facilitate the spreading of the seed, they are also aiding in the germination process due to the seeds passing through their digestive systems.” Thus explains that the tortoises don't just help on way, they help out in many ways.

With this, they can spread many invasive plant species which can overtake forests and ruin ecosystems. One example is the fern. Ferns are a short plant that blocks a lot of sunlight. The fern grows very quickly and covers other plants' sunlight. Deer hunting also helps the farmers.

Another way they are damaging is that invasive species could be a potential fire hazard. A fire occurred at the Hanford Reach National Monument and cheatgrass was partially to blame for the fire (Erickson and Lusk 1). Cheatgrass is a winter annual plant, which means the seeds sprout when the temperature is cold. The plant can outperform spring plants for water and other nutrients, which allows them to spread rapidly and stay there. By the time summer rolls around, the plant becomes dry and flammable.

The Endangered Species Act was passed into law on December 28, 1973, the act was designed to conserve and save threatened plants, animals, and their habitats. The Endangered Species Act is widely supported, and around 87% of Americans agree that the act is a successful way to keep endangered and threatened animals safe. The act has numerous positive effects on plant, and animal life, these positive effects are saving endangered and threatened species, preserving their ecosystem, and protecting plants and animals that assist in treating diseases. According to the U.S Fish and Wildlife Service, 99% of species ever listed on the endangerment list remain on the planet today. The Bald Eagle is one of the many species saved by the Endangered Species

Humans have become desensitized to pollution and degradation of the environment. The use of non-recyclable materials and disposing of waste irresponsibly has become something that we see every day, and we do not acknowledge as something harmful, because it does not directly affect us. However, there are both fictional and nonfictional examples of excessive use of resources and the misuse of materials that we do have, that can bring to the attention the damage that we are really causing. Two examples of this are Dr. Suess’ The Lorax, and Easter Island. Although very different, both the inhabitants of the town in the Lorax and Easter Island both contributed to degradation of the environment.

Invasive Species Invasive, alien species, those which colonise, expand and out compete native species (Smith & Smith, 2009), are a major threat to our habitats, terrestrial and aquatic species, and biodiversity. Agricultural and leisure industries are affected as well as conservation welfare and the continued wellbeing of man, flora and fauna. Whole ecosystems can be distorted and the economic cost of awareness, prevention and eradication systems is substantial. Most invasive species have been introduced by mandeliberately or otherwise. As an island, Ireland has been subjected to less invasive species than larger nearby land masses e.g. Europe, but islands have a less diverse species population and are therefore more vulnerable when invaded.
