Fire, ice, asteroids and pole shifts are bogeymen with which we distract ourselves from the real threat of our time. In an age when everyone invents his own truth, there is no community, only factions. Without community, there can be no consensus to resist the greedy, the envious, the power-mad narcissists who seize control and turn the institutions of civilization into a series of doom machines.
The old school of thought would have you believe that you'd be a fool to take on nature without arming yourself with every conceivable measure of safety and comfort under the sun. But that isn't what being in nature is all about. Rather, it's about feeling free, unbounded, shedding the distractions and barriers of our civilization not bringing them with us.
