Invasive species are non-native species that can significantly disrupt an ecosystem’s balance through their introduction, multiplication and spread. In their newly introduced environment, they may cause severe damage to the native species, potentially resulting in habitat destruction, decreased biodiversity, the spread of disease, and even the displacement of the local species. Invasive species are considered hard to eradicate since they can reproduce rapidly and often have no natural predators. Human activity, such as transferring plants and animals between countries and/or even continents, can be largely responsible for their spread. As individuals, it is important to stay informed about the risks that come with the introduction of invasive species and to take responsible action when travelling or when performing acts such as fishing or gardening.
