I love your closing line:
"Naturally Extra Terrestrial Migration is on the horizon."
And I agree - tho I'm not sure I'm interpreting it how you meant it!
I see us moving off this planet sooner than later, see my posts on Elon Musk and SpaceX... I'll be writing more about his goals at some point.
And of course, when we navigate to new lands or new planets, we are naturally sailing over the horizon, past our comfort zone, and into the unknown. So your line is so evocative in many ways.
Anyways, thanks for reading and commenting - I look forward to more.
