During the World Wildlife Fund’s Plastic Policy Summit in March in Washington D.C., I grabbed coffee in a white ceramic mug provided by the convention venue. Reusable mugs seemed unusual amid today’s prevalence of single-use cups, prompting me to reflect on how we have normalized single-use: I bought yogurt and soda in returnable bottles in Beijing; generations before us grew up with reuse. Why did we move away from it?

As a world still dominated by patriarchy struggles with a deadly pandemic, the countries that have successfully navigated the global COVID-19 pandemic are distinguished by the gender of their leadership.  Across the world, countries headed by women and representing diverse cultures—from Germany, Norway, and Finland, to Taiwan, New Zealand, and Namibia—have managed the crisis more effectively, with fewer fatalities and less livelihood loss than others. But what distinguishes these health winners is not just the female shape of their leaders but the feminist shape of their societies. Even more gender-balanced societies headed by men—like Canada—do better in health crises than their less equitable peers like the United States. On the other hand, the most patriarchal countries headed by regressive strongmen do worse at every level of development. Today, we see this in Brazil, which until recently had managed health crises well under less masculinist leadership.
