Are invasive species harmful or beneficial for an ecosystem? Invasive species can have an overall negative or positive effect on the environment around them. It is easy to create a bias in viewpoints when looking into different topics of invasive species. Many people believe invasive species are destructive to the environment they inhabit. While, others believe they take on new beneficial roles that benefit the resources around them. As you look at the influential features of different invasive species it will open up insight on whether or not invasive species are beneficial for an eco-system.
An invasive species can be defined as an organism that is introduced into a new, non-native environment. Invasive species are often described as an …show more content…

Invasive species affect biodiversity as well as habitat eco structure in the environment. The highest threat invasive species pose to biodiversity is the threat on endangered species. Nearly 50 percent of the 1,900 endangered species are endangered because of invasive species and the ways in which it can alter an ecosystem. Invasive species are currently the second leading threat to biodiversity. Invasive species alone, have a stronger negative affect on biodiversity than forest clearing, disease and pollution combined. For example, the Nile perch is a species of fish that was introduced to Lake Victoria as another resource for food. This new non-native fish quickly became a devastating predator and has eliminated over one hundred species of fish. The Nile perch was able to do this because they reproduced rapidly and they could out compete native fish for habitat and food. Invasive species are aggressive species that can control a newly introduced ecosystem by spreading quickly and taking over the …show more content…

The Asian oyster is an invasive species that helps benefit the ecosystem it inhabits. The Asian oyster filters out water pollutants, improving the water quality they live in. They also grow fast and prevent disease which can allow the oyster industry to revitalize. Often, efforts will be made to remove an invasive species, which can have a negative effect on an ecosystem with a newly adapted balance. These attempts funded by the government to remove a species could just be a waste of tax dollars and

The location of where the oysters are grown and the conditions of that environment are extremely important to the oyster industry. The Croxtons explained that the oysters are put in cages that are elevated above the muddy sea floor so they can eat better food and have a better lifestyle. Another theme of geography that is used is human-environment impact. The Croxtons are impacting the environment and ecosystem of Chesapeake Bay in a beneficial way by harvesting oysters. The oysters help filter the water in the

They’ve crippled the Everglades’ populations of opossums, rabbits, bobcats and foxes, thus dominating the food web to such a degree that there’s not much of a web anymore. Invasive pythons aren’t the only non-native species that threaten the Everglades ecosystem. There are invasive plants too, hurting the balance of the Everglades, not only choking out native species (some vine-like plants actually grow over original trees and plants), but growing so thick that they block water flow and movement of

The United States has an abundant amount of health organizations that’s responsible for protecting the public’s health by regulating items, restricting certain products, or simply to provide the population with helpful information to promote healthy lifestyles. The FDA is one of the most recognizable health associations that are deemed to do what exactly people expect, to protect their health. They’ve been around for over a century and everyone thinks they’ve been doing their job. In reality, that’s not the case for the most part. The FDA approves many harmful ingredients and/or products that actually are detrimental to the health.

Poaching and illegal hunting can cause an off set in the ecosystem by overhunting animals. When one animal population decline drastically, other organisms are affected too. The decline in native predators is the main cause for overpopulation of animals like deer. Deer overpopulation has led to rapid decrease vegetation life causing other animals to be put at risk. Removing predators from the food web disrupts the entire balance of an
