Human effort to eradicate disease-causing organisms (Poliovirus). This situation may appear when alien species are introduced unintentionally or deliberately into an area. Some of them may become invasive and cause damage to indigenous species.

The introduction of African catfish Clarias gariepinus for aquaculture is threatening the indigenous catfishes in rivers of India.
