In the modern world, the fastest way species move is through the transportation of people. However, when species are moved, it sometimes turns them into an invasive species. Invasive species are living organisms that are not native to an area and cause economic, environmental, or human health damage. Over the years, invasive species have become one of the leading causes of global biodiversity loss because they negatively impact new environments by outcompet- ing native species and disrupting human activities. Additionally, invasive species are known to spread quickly and bring new diseases, which makes them deadly to other species in the same environment.

Some reasons humans move species are to solve problems in an area such as reducing a population of harmful pests, but also because human activities are destroying habitats and environments. These reasons can be further divided into two different causes of movement: intentional and unintentional. Invasive species are usually moved unintentionally,
