ARE VIRUSES ALIVE?

 

    For about 100 years, the scientific community has repeatedly changed its collective mind over what viruses are. First seen as poisons, then as lifeforms, then biological chemicals, viruses today are thought of as being in a gray area between living and nonliving: they cannot replicate on their own but can do so in truly living cells and can also affect the behavior of their hosts profoundly. Finally, however, scientists are beginning to appreciate viruses as fundamental players in the history of life.

 

    To Be or Not to Be

 

    The seemingly simple question of whether or not viruses are alive, which my students often ask, has probably defied a simple answer all these years because it raises a fundamental issue: What exactly defines “life?” A precise scientific definition of life is an elusive thing, but most observers would agree that life includes certain qualities in addition to an ability to replicate. For example, a living entity is in a state bounded by birth and death. Living organisms also are thought to require a degree of biochemical autonomy, carrying on the metabolic activities that produce the molecules and energy needed to sustain the organism. This level of autonomy is essential to most definitions.

 

    Viruses, however, parasitize essentially all biomolecular aspects of life. That is, they depend on the host cell for the raw materials and energy necessary for nucleic acid synthesis, protein synthesis, processing and transport, and all other biochemical activities that allow the virus to multiply and spread. One might then conclude that even though these processes come under viral direction, viruses are simply nonliving parasites of living metabolic systems.

    What is it about Serena that inspires such vitriol? Is it that she dominates in a sport that was once considered to be for the upper crust at country clubs? One would think that Althea Gibson and Arthur Ashe had put that idea to rest decades ago. Is it that she is considered too aggressive on the court? John McEnroe and Boris Becker seem to take the prize for that. Is it because she wins too much? To hate someone merely because he or she is great only speaks to one's own insecurity. To attempt to and fault with someone because you cannot figure out how or why they win so often only shows that you have already lost. Or is it that she is unapologetically black? A HCarefreeBlackGirl who speaks her mind, supports her people, and whose only real opponent is herself.

   The formula for calculating people’s environmental footprint is simple, but widely misunderstood: Impact = Population x Affluence x Technology (I = PAT). The global rate of consumption growth, before the pandemic, was 3% a year. Population growth is 1%. Some people assume this means that the rise in population bears one-third of the responsibility for increased consumption. But population growth is overwhelmingly concentrated among the world’s poorest people, who have scarcely any A or T to multiply their P.

    Yet it is widely used as a blanket explanation of environment breakdown. Panic about population growth enables the people most responsible for the impacts of rising consumption (the affluent) to blame those who are least responsible.

    Shimmering white and gracefully statuesque, the Mount Washington Hotel is a granite fortress, a manmade anomaly among the raw wilderness of the surrounding White Mountains in remote northern New Hampshire, U.S. Even to this day, the hotel is geographically secured by 800,000 acres of the White Mountain National Forest around it. This was the main reason why the Hotel was chosen for a World War Two meeting – a meeting that shaped present-day global economic policies.

    We are at the beginning of a long road to rethinking and rebuilding supply chain models to encompass not just financial priorities but also business operations continuity in the most trying of circumstances. Executives from France and Italy, for example, are discussing ways to remake their businesses in the wake of the Covid-19 pandemic. Their specialty is supply chains. They are smart people at the core of the world’s most sophisticated and valuable systems of manufacture, shipment, and inventory, and yet many of their supply systems staggered in the past few months – the byproduct of reliance on old business models.
