Bulls can do nothing to demand justice. They can only defend themselves as best they can in a fight with a pre-determined ending and die never knowing why they were forced to endure such a painful and prolonged death. It's up to us, as a civilized society, to call for an end to the Running of the Bulls and bullfighting.

Going meat-free can make a huge difference. Studies show that vegetarians are, on average, 10 to 20 pounds lighter than meat-eaters and that a vegetarian diet reduces our risk of heart disease by 40 percent and adds seven or more years to our lifespan.

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.

Although we have, in theory, abolished human slavery, recognized women's rights, and stopped child labor, we continue to enslave other species who, if we simply pay attention, show quite clearly that they experience parental love, pain, and the desire for freedom, just as we do.

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.

Why go for a costly, sickly, mass-produced purebred when shelters are full of one-of-a-kind mixed breeds who are literally dying for a home?

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

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

Give your dog or cat respect, patience, understanding and love. And if you just change to one vegetarian day a week, that's a wonderful step that will save animal lives. It means you have chosen something kind instead of something cruel.
