Covid-19’s history is not yet fully known, but the links between animal and human health could not be clearer

It can feel wrong, or simply impossible, to focus on anything other than getting through this most challenging moment. It is reasonable to argue that since lessons will not reduce our immediate suffering, we should learn them once we’re through this. But the vulnerability that makes the present so painful is exactly why some discussions cannot wait. The suffering we stand to reduce or increase by the threads of action that we begin to unwind now could be magnitudes of what we’re currently experiencing.

Imagine that while your country practised social distancing, your neighbouring country responded to Covid-19 by packing citizens into gymnasiums by the tens of thousands. Imagine if, in addition, they instituted genetic and pharmaceutical interventions that helped their citizens maintain productivity under such adverse conditions, even though this had the unfortunate side effect of devastating their immune systems.
