The still-untamed SARS-CoV-2 pandemic under-lined, again, two important facts that have been known for a long while but conveniently forgotten by humankind. One is that we are profoundly linked to other organisms and nature, and the other is that human-driven distribution chains are global and fast. Neither should be a surprise, yet it seems that both caught people at individual and organisational levels unprepared and unaware. It is a no-brainer that if someone can arrive at literally the opposite part of our globe in about 24 hours, she can also bring back any-thing from there in the same time span.
