a great way to bring about animal liberation.

I hope SeaWorld is exploring how, like Ringling, it can get out of the wild animal business.

Perhaps one of the most important things you can do for human beings is wean them off an animal-based diet. It hardens the arteries and runs up our health-care costs. The last thing a poor person can afford is a heart attack or cancer or a stroke. And that's all linked to a meat-based diet. I think animal liberation is human liberation.

Perhaps measuring animal intelligence by comparing it to human intelligence isn't the best litmus test.

U.K. citizens fleeing the Middle East and Japan have been allowed to take their animal companions with them on evacuation flights. The U.S. is not so civilized, and that's a blot on our national copybook.

By adopting a wonderful mutt, you'll save a life and help reduce animal homelessness while also boosting your chances of a more robust new furry friend, as mixed-breed dogs have demonstrated better health and longer life spans than their purebred cousins.
