A Slow Draw

Photograph by Richard Barnes

Because rubber sap flows best at night, tappers in Xishuangbanna, China, use headlamps to light the trees while they work, as shown in this time exposure. The latex drips into cups from incisions in the bark. A typical tree produces a few ounces’ worth of rubber a day.
