Sustainability/Ethical Eating and Paganism/Witches

So, a heated discussion ensued on our Circle Yahoo Groups page. The Circle decided to have topics of discussion during our potluck. We'd have a different topic each month and a lead to keep the discussion track.

We have our Ritual first, then our potluck/gathering time.

Someone generously offered to speak to our group about ethical eating and sustainability. Boy, did that ever open a can of worms!

Now, I know how I feel. I feel that sustainability/ethical eating has a lot to do with being Pagan. But I now pose the subject to you all, my Pagan/Witchy friends.

Do you feel this is an appropriate topic of discussion and has relevance to Pagan religion?
