COVID-19, Pandemics and How They Will Change the World For the Better

I’m not a biological ‘fatalist’, but there are several reasons why epidemiologists were attempting to plan for a pandemic and why the Obama administration was empowering institutions, creating protocols and organizing resources that could be mobilized quickly, before the COViD-19 outbreak, not for this one specifically, but one of some kind. Viruses, bacteria, mycoplasma and other microbes fill the world at a microscopic level…they are everywhere, all of the time. Our own bodies contain far more of them than we do of our own some three trillion cells. Fortunately, most of them do not cause us disease, at least as long as we remain healthy. Many of them, in fact perform valuable functions in us, beneficial ones, without which our lives would be the poorer. Disease too is part of life’s ‘plan’. Its agents are dynamic. Today’s diseases are not those of the past. We evolved together. They mutate and sometimes ‘leap’ across species boundaries. A study of biology and disease reveals a function of disease or at least a consequence to the health and evolution of a species. It may sound heartless to put it this way, but disease is very much a part of living. With this new disease, COVID-19, as with others, it is selective, affecting those whose health is compromised in some way disproportionately, killing those most susceptible, the weak and those may include those surprising to us. As in most things concerning life, nothing is so simple as our concept of strong and weak. Disease is a part of the process of natural selection that has always been in effect in the world.

On Amelanchier / Serviceberries: Their Susceptibility to Rust and Their Use in our Gardens

Sometimes we are drawn to plants by memories and sentiment, plants we have early associations with.  They can regularly appear in our palette, our quiver of plants, that we might choose from.  We all have our preferences, our biases.  Sometimes the mismatch might only be aesthetic other times it can be a problem related to our site conditions.  When we include these plants they may struggle, yet persist in the garden, maybe demonstrating to others their ‘ill-fit’.  When a plant is a poor fit, its inclusion can become a glaring error to others that we are blinded to.  Diseases can present such a problem, diseases that can be problematic in our area, or that our site is simply unfortunate enough to suffer from.  ‘Rust’ diseases,  Gymnosporangium spp., can be an issue here.  In the case of Serviceberries, it can be disfiguring and debilitating.  Several of these species attack Rose Family members, that include the Serviceberries, which seem particularly susceptible, though it doesn’t kill them.  Diseased, stunted and suffering, unwilling to just die and put us both out of our misery, these plants continue.  It is akin to being drawn to the wrong lover or life partner…it’s not going to work out and we simply can’t seem to help ourselves.
