Keeping our water and land free of invasive species takes all of us doing our part. Considering what we dump into the waterways and ground before hand can make all the difference.

Visiting the Great Lakes Aquarium helpedĀ  us learn more about native vs. invasive fresh water aquatic plants and fish. Through games students simulated how aquatic invasive plants and fish change the natural balance. They either eat too much of a plant needed by another native fish or grow too fast overtaking other plants that would typically grow in that environment. Any change affects everything. Eventually the native species can not compete and either die away or move.

It was particularly interesting to learn that gold fish dumped into a small pond negatively affects the pond tremendously. Goldfish eat a lot, changing the vegetation and ability for other animals to breed and grow. If you have a goldfish and are unable to care for it it is best to give it to someone else to take care of rather than a near by pond. A pond near to UMD had to be drained completely , cleaned and refilled because of theĀ  of gold fish population taking over the native species and the connection of the pond stream feeding into Lake Superior.
