Yes, I've heard of it.
I don't believe it. It seems like just a lame explaination for natural happenings. It sounds Hippy-ish and cult-of-eden-ish. I don't like it really. Metabolism of algei? Really? It doesn't make the first bit of sense.
With all due respect to you, I really think it's a load of rubbish.
I see you too! XD
