Four types of snakes will never be allowed to be brought into the United States again.
After years of people dumping the exotic pets in the Everglades, a new ban hopes to restore the natural ecosystem.
The ban was announced in the Everglades this morning by U.S. Senator Bill Nelson and Secretary of the Interior Ken Salazar.
After Hurricane Andrew hit South Florida in 1992 it was speculated that several pythons escaped from pet shops and homes and started breeding in the Everglades.
Supporters of the ban say the invasive species have affected the ecosystem and poise a threat to wildlife.
Opponents say the ban is overreaching.
The new rules prevent anyone from importing the four banned snakes but does allow people who already legally own them to keep them.
