The equator is going to be a crucial determiner in future times. If you’re too far away from it you have to deal with winter, if you’re too close to it it’s like being locked in a parked car. Somewhere close to the equator, not too close to have your brain fried. Put it this way, air conditioning is a good thing. We are searching for a place that would require neither air conditioning or furnaces that keep us from freezing. The perfect clime for the perfect people, that is what we seek. Underwater mountain ranges north and south of the equator are ideal for that, not too far in either direction. What do we have now, ships delivering consumer products? What a waste. Have them carry rocks and sediment to raise the ocean floor.
