摘要

在撰写本文时,新冠肺炎大流行已进入第二波,世界许多地区的感染率每几天至两周翻一番。这种几何(或指数)扩张是所有物种无限制种群增长的标志,从亚微观病毒颗粒到细菌,再到鲸鱼和人类;这表明生物繁殖模式中存在一种“分形几何”。在自然界中,种群爆发总是会因内源性和外源性负反馈的出现而逆转——繁殖力降低、资源短缺、空间竞争、疾病等,有助于将参考种群恢复到承载能力以下,有时会急剧崩溃。智人也不例外——我们的物种正接近由化石引发的约200年瘟疫般的种群爆发的顶峰,这开始引发严重的负反馈表现,包括气候变化和新冠肺炎本身。人口将急剧减少;从理论上讲,我们可以在自然造成的混乱崩溃或国际合作之间做出选择,以计划一个有管理的、公平的人类企业收缩。

fractal biology of plague and the future of civilization
At the time of writing, the CoViD-19 pandemic was in its second wave with infections doubling every several days to two weeks in many parts of the world. Such geometric (or exponential) expansion is the hallmark of unconstrained population growth in all species ranging from submicroscopic viral particles through bacteria to whales and humans; this suggests a kind of ‘fractal geometry’ in bio-reproductive patterns. In nature, population outbreaks are invariably reversed by the onset of both endogenous and exogenous negative feedback – reduced fecundity, resource shortages, spatial competition, disease, etc., serve to restore the reference population to below carrying capacity, sometimes by dramatic collapse. H. sapiens is no exception – our species is nearing the peak of a fossil-fueled ~200 year plague-like population outbreak that is beginning to trigger serious manifestations of negative feedback, including climate change and CoViD-19 itself. The human population will decline dramatically; theoretically, we can choose between a chaotic collapse imposed by nature or international cooperation to plan a managed, equitable contraction of the human enterprise.
