Do you know what invasive species are?
Usually that is a plant or animal introduced to an area where it does not exist. It doesn’t necessarily have to be from another country. It is not only plants or animals but it an be any kind of living organism like fish, bacteria, insects etc.
So what is the problem with that?
The problem with invasive species is that they do not have natural enemies so they can multiply very quick and cause harm to native flora and fauna and even to humans.
How do they get introduced to an area?
There are so many ways……but most of the time its by human activities and we are not always aware that we are introducing an invasive species to an area.
