This is another beautiful video brought to my attention by the good people at Vox. Well worth 7 minutes of your time to better understand how we got to 7 billion people and why it is very possible that even us lowly humans might be having an impact on our blue marble.
I think it is appropriate that the sound to indicate another million people is a click that reminds one of the sound a Geiger counter makes. Are humans radio active to the blue marble. No, we are not. It’s wonderful that we are here and some day soon there will be 11,000,000,000 souls living on the blue marble at the same time. In reality, we have no other choice. The question is: how will we manage the needs and desires of 11 billion of us at the same time? This question isn’t even on the radar of the Republican Party and the fact that it is not should be considered a national security issue. imho.
