Transcription: One of the most striking images from space is how incredibly thin the atmosphere is. It's only about 8 miles deep or 10 miles deep. There's just very thin air above that. It's amazing to look at from space. You see this thin veil like an onion skin around the blue of the Earth and that's all that protects us from death out in space. So it is a real reminder of just how fragile our atmosphere is and how fragile the Earth is need to be careful what we do.
