Meet Heng Kim Seng, Cambodia’s bat man. In a few years, he went from rice to riches all because of bats.
Under the Khmer Rouge, he hauled human waste to make the rice grow, and now he sells bat feces or “guano” as a natural fertilizer, a thriving business that could even save lives.
It all started one night, back in his home village in eastern Pursat province, where he returned after the regime fell. At dusk, Seng watched bats by the thousands streaming out of palm trees and struck upon an idea.
