I wonder if you are as amazed by this as I am? It shows how thousands of tons of Sahara sand are carried on the wind currents each day, ending up over the Amazon and come down in rain which sustains and fertilizes the lush green of the forests. The sand contains plankton. I wonder if that is how our condition came about. Hmmmmmmm..... Steve Frey, where are you??? At any rate, I couldn't stop watching this. I hope you enjoy it. It is two hours long, FYI, but well worth the time. There was so much I had never heard before as to how our whole planet is sustained by the amazing, amazing and powerful things that go on in the atmosphere that we are not even aware of. www.pbs.org/wgbh/nova/space/earth-from-space.html

Violet, This looks really interesting. I watched the first 10 minutes and look forward to seeing the rest. I didn't realize that the nova series was available online. Thank you for posting.

I'm so glad to know you watched it. You'll see them explain later on in the film how the sand and dust from the Sahara is carried on the trade winds all the way to the Amazon. The sand carries plankton with it which fertilizes the Amazon. It makes me wonder what things are being carried to our country and from where that could be contributing to our issues. It also makes me realize that Steve Frey's sponge theory could be valid. A long time ago I saw a documentary on how they blow up the red coral reefs in Hawaii, and if the wind currents carry that around the earth, we could certainly be affected by it, perhaps.
