Undercover investigations threw back the curtain on the systemic exploitation of animals on factory farms.

There are new ways of producing food, film, clothing, and research that steer clear of using animals. Some of those products are functionally equivalent or even superior to what we're used to.

There are many innovators hard at work seeking to perfect alternatives to meat, milk, and eggs. These food products will, like computer-generated graphics or photography or sound systems, just keep getting better and better until there is little difference between an animal-based protein and a plant-based one, or farm-produced versus cultured meat. That will make it easy for people to make the kinds of choices that will usher in a world with far less violence.
