BALI, Indonesia — It’s just after sunrise here in Bali, and a group of locals are preparing to sail their wooden boats out to a bay off Nusa Lembongan, a small island southeast of the tourism hotspot. They’re neither fishermen nor tour guides. They’re farmers, cultivating a watery crop that promises to be part of the solution to the increasingly urgent problem of marine plastic waste that’s become woven into the Bali experience for the millions of people who visit the island each year.
