    Cane toads are considered invasive species in Australia as they are destructive to the native species and have no natural predators there.

    Thus they can not be considered simply non-native

    Explanation:

    Cane toads are considered an invasive species in Australia because they have had a significant negative impact on the country’s ecosystem since their introduction in 1935.

    What is an invasive species?
    An invasive species is a non-native species that has been introduced to an area and is causing harm to the environment, economy, or human health.

    What is a non-native species?
    A non-native species is simply a species that is not native to a particular region or ecosystem.

    Cane toads are considered invasive because they have several negative impacts on the Australian ecosystem like
    1. They are toxic to many native animals, including birds, reptiles, and mammals.
    2. They can cause illness or death when they are consumed.
    3. They also compete with native animals for food and habitat and can disrupt entire food chains.
    4. Additionally, they are also prolific breeders, and their population can quickly explode, which makes it difficult to control their spread.

    Invasive species are a significant threat to global biodiversity and can have long-lasting, harmful effects on the environment. Therefore, it is essential to distinguish between non-native species that are harmless and those that are invasive and cause significant harm to the environment.

    In the case of cane toads in Australia, their negative impact on the ecosystem makes them a prime example of an invasive species.
