Saving individuals

Planet Earth II, the new BBC documentary narrated by Supreme Voice of Nature Sir David Attenborough, devotes one of its six episodes to animals living in cities. It’s unsurprisingly great. (Even if the ultimate masters of urban living, pigeons, who you might expect to be celebrated in this context, instead spend the episode getting unceremoniously eaten.) The “Cities” episode has to walk a delicate line, heralding animals’ ability to adapt to human landscapes without failing to acknowledge that humans overwhelmingly destroy habitat rather than creating it. It mostly leans to the optimistic side of the line; one segment makes New York City seem like a wildlife paradise.

The darker side of cities is represented by a segment on hatchling sea turtles. The turtles use the shine of moonlight on water to guide them from their nest in the sand into the ocean. Unfortunately, we humans love to shine lights even brighter than the moon, and more than half of the tiny turtles are drawn away from the ocean by the city’s lights.

As Attenborough narrates, footage rolls of the baby sea turtles gamely clambering across sidewalks and onto busy streets, heading for the ocean that isn’t there. The bodies of roadkilled turtles are visible in the background. One turtle makes it across the street, then tumbles halfway into a storm grate and gets stuck, lost to view save for one forlornly-waving flipper.

As soon as the episode ended, I began typing into Google: “planet earth 2 did”—at which point Google helpfully autocompleted the rest of the sentence: “planet earth 2 did they help the turtles“. Everyone else who had seen the episode wanted to know, too.
