Discovery Channel Song

I haven't seen this commercial in months, but a short version was just on as I was watching "Dirty Jobs." The first time I saw it I just fell apart. I laughed and cried, and watched it over and over. It still makes me cry. Tears of joy and pride. We are a remarkable species living on a remarkable planet. The very fact that we're capable of realizing this just fills me with hope and happiness. 3 hankies
