Bangkok-born photographer and software developer Akkara Naktamna captures nature’s ominous side. He says, “I often encounter weird, even eerie, environmental elements, such as various plants that, gorged on the city’s pollution, burst into gigantic mutant creepers, steadily devouring everything around them. They seem to be biding their time to wreak vengeance upon nature-destroying man.”
