Do you think that human life is worth more than the life of an animal?

Or certain animals? What about dolphins? Or a chimp? Or a cow? Or a dove? Or an alligator? Or a tuna? Or a clam? Or an ant? Is there a limit where the animal's life becomes almost as valuable human beings? What is that limit?

The ultimate value of life depends on the sensitivity and the power of contemplation rather than mere survival. Aristotle (http://www.brainyquote.com/quotes/quotes/a/aristotle132267.html)
