I've been active in animal rights and all kinds of environmental stuff and children's charities over the years.

I'm such an advocate for animal rights and environmental rights.

I'd say that animal rights and environmental issues have always been at the forefront of my mind.

If possessing a higher degree of intelligence does not entitle one human to use another for his or her own ends, how can it entitle humans to exploit non-humans?

The time will come when men such as I will look upon the murder of animals as they now look on the murder of men.

I am in favor of animal rights as well as human rights. That is the way of a whole human being.
