We have all sorts of theories on this pandemic, but we can be sure that human activity is causing dramatic changes in our planets ecosystem, the results of which we don't fully understand and can't possible predict accurately. What we can be sure of is that we are, by human greed and blind ideology, creating a world vastly different from the one we inhabit at present. Habitats and species disappear, new forms of bacteria and viruses emerge and we have no idea how they will affect us as a species.
By the illusion of ever increasing growth, we are opening a Pandora's box of complexities, and few are in our favour. Covid19 could be just another new pattern emerging in natures fight for survival against human plundering and destruction of its delicate balance. What we can be very sure of is, in any battle of humans against nature, nature will prevail and the human species will fall. We work with nature as part of it, or we fall as a damaging parasite, sadly we may take millions of innocent species with us.
