Eric, Sorry to not have replied. Thanks for your response to my request. I was hoping to get a few more responses, but did not, and then your email got buried. I have a DVD that may be as good as any - it's called Gifts from the Earth and is part of a series of 3-4 videos on Planet Earth, but it is from the 90s (or 80s).

I may have a copy on DVD. Regards, Eric Pyle On 4/6/10 10:14 PM, Elizabeth Shadman wrote: I would love to have something like that as well!
