@Tuta 
The invasive species that are bad for the environment are usually non-native invasive species. These plants colonize habitats, and exclude the native plants and animals. Since they decrease native biodiversity, they are bad for the environment.

It is better to guide the user to an answer rather than doing all the work yourself or simply giving them the answer. We discourage giving out answers without letting the asker at least take some part in the analysis - the aim of this site is to teach.
