âI guess the grass is itself a child, the produced babe of the vegetation.â Perhaps Walt Whitman had this weekâs guests on Sea Change Radio in mind when he wrote those words, as we talk to two entrepreneurs who, in very different ways, are using natureâs bounty for innovative purposes. First, we speak to Hawaiian-based bicycle maker, Barret Werk, who uses bamboo, the strongest grass around, to make his bike frames. Then, we revisit host Alex Wiseâs discussion with Bay Area-based sea forager extraordinaire, Kirk Lombard.
