Invasive non-native species are quite a problem for scientists and people interested in the environment. They can cost the government money, especially when they become established, and also cause other issues.
In addition, invasive non-native species are not good for the environment. They can cause some problems for rare species, and might alter and damage the ecosystems in which they are found. Some people think that theenvironmental impacts of invasive non-native species are growing and getting worse. Invasive species are thought to be a threat to biodiversity.
As well as the impacts they have on wildlife, invasive non-native species can sometimesimpact people too. They can cause waterway clogging and flooding, and have also been known to impact boats and other things.
The effect of an invasive non-native species is not a one-off event. Once a species has been introduced it can spread further and cause more damage. If we don't act, the problem of invasive non-native species may get worse, which could be more expensive and might lead to other problems.

Whether you are interested in the environment or not, the problems caused by invasive non-native species affect us all. For a start, they cost us billions of pounds - it has been estimated that they may cost as much as £2 billion every single year in Britain alone.
But invasive non-native species are not only an economic problem, they are also a well-known threat to our environment. From challenging the survival of our rarest species to damaging some of our most sensitive ecosystems, the biodiversity impacts of invasive non-native species are severe and growing. Their impact is now so significant that they are considered to be one of the greatest threats to biodiversity worldwide.
It's not just our wildlife that suffers - invasive non-native species can also have an impact on the way we live. For example, if invasive aquatic plants become established in the wild they can clog our waterways, exacerbate flooding, disrupt the navigation of boats, interfere with recreational activities such as fishing, and remove oxygen from the water, which in turn can harm fish.
Once a species has been introduced, the problem persists and escalates as the species spreads further. If we don't act, the problem of invasive non-native species will continue to escalate at an ever-increasing rate, causing us to feel more of the impacts and incur more cost every year.
