“Indeed, Judaism as a way of life, seeks to inculcate in us a consciousness of the Divine Presence in the World and respect for life accordingly. The more we care for life, the closer we are in fact to God. Accordingly, an ethical vegetarian way of life expresses the most noble and sublime values and aspirations of Judaism itself, bringing us closer to its vision for society as a whole.”

Context: To my mind, the expression of divinity is in variety, and the more variable the creation, the more variable the creatures that surround us, botanical and zoological, the more chance we have to learn and to see into life itself, nature itself. If we were just human beings, living in a spaceship, with an algae farm to give us food, we would not be moved to learn nearly as many things as we are moved by living on a world, surrounded by all kinds of variety. And when I see that variety being first decimated, and then halved — and I imagine in another hundred years it may be down by 90% and there'll be only 10% of what we had when I was a child — that makes me very sad, and very despairing, because we need variety. We came from that, we were born from that, it's our world, the world in which we became what we have become.
