The number of degrees that the Earth is tilted. The number separating us from nonseasonal perfection. If only it had been evolutionarily beneficial for humans to migrate to the equator.
Summer is too hot. Winter is too cold. A perpetual spring would be ideal, no? Plant-life would flourish, meaning trees of Elven proportions and with some luck, plants with brains, but that’s pushing it.
If I ever write a novel, it will include the eventual achievement of the removal of Earth’s seasons, probably not a major role, maybe something that Humanity achieved in the years leading up to the story or just as a cameo, contemplating the viability of such a feat and how long it would take. But focusing on all the potential effects or even the possible destruction of the ecosystem too much for me. That kind of speculation is out of my league.
