Why are invasive species bad?
All plants contribute some good things to their environment, such as reducing carbon dioxide or providing food for animals, but invasive species can threaten the biodiversity of an environment. Invasive species can spread extensively and quickly, replacing native plants and thereby altering an ecosystem. Once the conditions of an area are changed, new species including pathogens may be able to survive where they previously could not. Why is biodiversity so important? A wide variety of animal and plant species is beneficial for several reasons: Ecologically, all living things are supported by other living things. When one species is removed, other species are likely to suffer. The more complex an ecosystem, the more likely it is to survive for a long period of time, and the less vulnerable it is to damage. Economically, the more variety there is in the natural world, the more likely we are to meet specific human needs. Everything we buy and sell originates from the natural world. Cultur
