“California is a leader when it comes to animal welfare, and today that leadership includes banning the sale of fur,” Newsom said in a statement. “But we are doing more than that. We are making a statement to the world that beautiful wild animals like bears and tigers have no place on trapeze wires or jumping through flames.”
California enacting these laws is important because its economy carries massive weight. If California were its own country, it would be the 5th largest economy on earth. When California sets regulations on any industry, those laws slowly become the national American standard.
Look at cars as an example. When emissions regulations are enacted, because California purchases such large amounts of cars, the auto-makers make that the standard for the rest of the country too.
