Scientists estimate that 1 in 6 bee species are extinct and 40 percent are at the verge of extinction due to habitat loss and pesticide use. The consequences are dire. Bees are major pollinators of food crops. Their extinction would threaten the earth’s ecosystem, and food chains upon which we all depend. Many of us already know this since bees have the dubious distinction of being extinction celebrities. But bees are only one part of the calamitous biodiversity loss the world has suffered in the last five decades. The World Wildlife Fund and the Zoological Society of London estimate, for example, that between 1970 and 2018, there was an average 69% decline in wildlife populations across the globe, and an 83% decline in global freshwater species. Scientists believe we are in the throes of a mass extinction (earth’s sixth), with species dying out at several hundred-fold their expected rate thanks to human activity.
Declines in biodiversity pose an existential threat to life on earth. We rely on biodiversity for our food, air, water, medicine, and almost everything else that we need to sustain humanity. Yet most people don’t even know what biodiversity means, let alone what to do about it. Definitions are a good place to start. According to the Convention on Biological Diversity, biodiversity refers to the “variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems.”
As a lay person, the only clarity this definition adds to the word itself is that biodiversity is complicated. Its complexity–arising from the scale and diversity of species, their interconnectedness, lack of data, and spatial as well as temporal heterogeneity–makes biodiversity a very difficult problem to model. There are 8.7 million species on earth. What happens when one of the 42,000 that feature on the IUCN’s red list of species threatened with extinction goes extinct? How much do we even know about any of them? What are the ripple effects of species extinction on the intricate web of life, locally, globally, today, and tomorrow? Read more »

If Joan Didion were alive today, she might write an essay about Prince Harry and include it in an updated version of Slouching Towards Bethlehem. She might write a passage like the one she wrote about Howard Hughes:
