That was an excellent show, I heard some things I'd never been aware of before, like the 4000 mile diameter jet stream around the antarctic that stirs the ocean almost 2.5 miles deep.
Also how most of the oxygen created by the Amazon rain forest never leaves the forest, but the algae blooms created by the Amazon river carrying crap into the ocean creates much of the oxygen which benefits us.
It pointed out how the space program was much more than putting men on distant rocks, although that's what got all the press. The tremendous value of the scientific satellites and their ability to provide data that help us understand how the earth/nature works, has been of more value than Apollo.
But these aging satellites are not being replaced as the retire, so much of the scientific research will wither on the vine.
