People never seem to under stand that releasing foreign fish or animals into our environment is bad. May be this pictorial representation of the damage they are doing will bring the message home.
|A small section of a river crowded with foreign fish.|
|They have been out numbered. It took a while to find one local fish (the common snakehead in the center) among the introduced species.|
- Foreign species push out local competitors. They can drive local animals to extinction.
- Foreign species may have no know predators. They can become over populated.
- Foreign species can be more aggressive or prolific breeders. They compete with local animals for space and food, or prey on the local animals.
