At The Humane Society of the United States, we know how difficult it is to prevent cruelty to animals in movies because so many of the animal welfare problems occur behind the scenes in training, housing, and transportation, long before the animals get on the set.

If we could shut down all sport hunting in a moment, we would.

We've witnessed so many revolutions in our society. Think of transportation, photography, or communications. Things once unimaginable have become seemingly impossible to live without.

The good news is we are seeing an incredible surge in non-animal technologies in laboratories. With researchers using stem cells, visually impaired people may one day have new corneas and lenses grown from their own cells. That is likely to be a more effective and cheaper approach than using animals.

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.

If I had my personal view, perhaps that might take hold. In fact, I don't want to see another dog or cat born.

We believe in the Three Rs - reducing the consumption of meat and other animal-based foods; refining the diet by eating products only from methods of production, transport, and slaughter that minimize pain and distress; and replacing meat and other animal-based foods in the diet with plant-based foods.
