Hidden in the long shadow of Covid-19, 2020 has been a dark year. Scientists have been forewarning a pandemic like this for years, pointing to the rise in zoonotic pathogens— those that jump from animals to humans— as a reflection of the pressures people put on planet Earth.

Climate change, rupturing inequalities, record numbers of people forced from their homes by conflict and crisis—these are the results of societies that value what they measure instead of measuring what they value.
