We are in uncharted territory with the Ebola virus disease (EVD). The last time we had a plague that was this deadly was the Black Death in the 14th century, when there were only 450 million people in the world. That pandemic killed 30% to 70% of the population. There is no benchmark for EVD, which kills 3 out of 4 people it touches, and is emerging into a global population of 7 billion.
If we do manage to pull back from the abyss, or if enough of us survive the plunge, it will surely be because small groups of us have formed mutualistic communities for the express purpose of helping one another eke out a largely local living from a depleted planet Earth. We will be painfully aware, by then, that a sustainable lifestyle must involve subordinating our reproductive inclinations to the long-term well-being, not just of our own community, but of the larger ecological community on which our well-being depends. We will certainly understand that a global ecosystem is a sacred trust that demands our respect and, yes, our reverence. Finally, we will need the humility to understand that we need a healthy global ecosystem far more than it needs us, and that we need to invest at least as much of our treasure in husbanding that priceless natural legacy as in pursuing our own material well-being.
