Invasive Species
An invasive species is something that has a negative effect on the ecosystem. These organisms are usually brought here from somewhere else so they aren't native. Unlike popular belief an invasive specie can be from any kingdom not just from the animal kingdom. An invasive specie does not have just one collective negative effect. They can reduce animal population, take other species food, ruin fishing, cause creatures to leave there homes, kill baby animals (or eggs) and hurt creatures. These are just some main common affects that invasive species can have on biodiversity. There are many things you can do to stop the spread/destruction of invasive species.
Here are two types of invasive species that are very bad for our eco-system:

These fish are nick-named "The smacker" for a reason! They can 1.2 meters long, weigh over 27 kilograms, and can jump over 4.5 meters high! They eat 40% of their body weight daily, leaving native fish struggling for food because they eat phytoplankton and zooplankton, and this plankton being at the food chain, other animals suffer from its number decrease. These fish are known to actually "smack" boaters when the jump into the air. Rivers or lakes that are populated by these fish are not as nice for cottages, swimming or boating because a Silver Carp that jumps out of the water and hits a child on the head can knock them unconscious. Also, sadly, because of their bone structure they aren't usually eaten because it is a huge hassle to de-bone them.
This plant causes strife when on the loose, hence the name "loosestrife". This purple plant invades wet-lands and pushes out the plants living there. Animals are forced to find new habitats because the plants they eat are gone. This plant also makes finding shelter and raising young for animals a difficulty because the animals are not used to this new habitat. This plant even invades farmer's crops and pasture lands! To control these pesky flowers, in places they haven't reached full potential, you can pull out the plants, but as much of the roots as possible must be pulled out. Approved herbicides can destroy these but still keep other plants safe. It's natural enemy, the galerucella beetle feed on its leaves, flowers and root tissue so they eventually shrivel and die.
