The governor of Massachusetts has signed a law banning circuses and traveling acts from using elephants and other animals. Gov. Maura Healey signed the bill into law in August, and it will take effect Jan. 1, according to Boston.com. The law states that carnivals, circuses, and fairs will not be able to use some animals, including bears, elephants, giraffes, lions, primates, and tigers, for entertainment purposes.
