Biology is crucial for understanding the world around us and how we’re impacting it. But biology and other STEM fields have typically been dominated by white dudes. Enter Grist 50 Fixer Earyn McGee. Whether she’s out in the field lassoing lizards or tweeting under the moniker @Afro_Herper, McGee knows that diversity matters — in nature, and in the people who study it. 

This year’s Grist 50 features short documentaries on Fixers like McGee — emerging leaders who are tackling climate and justice from every imaginable angle. Check out the video above for a closer look at the herps McGee studies, and the implications for climate and equity.
