That's great, but what about all the other animals? They also possess a variety of remarkable intelligence capabilities. There is also the issue of sentience. Unlike plants, other animals have nervous systems that gives them the capacity to experience physical and emotional pain, etc. In fact, there is a book on this subject called Animals as Persons, by Gary Francione. I haven't read it yet, but I would like to at some point.

I have no doubt that most dolphins are more intelligent than some Americans..............
