For Chris Kobayashi and her husband, Dimi Rivera, it all started with Japanese cucumbers. "In 1997 we said, 'OK, let's grow Japanese cucumbers, but let's grow it organically,'" Kobayashi tells me as we walk around her farm in Hanalei Bay on Kaua'i's North Shore. "You know, because they are crispy, crunchy, and yummy and you can eat the skin and everything."

Walker has long backed policies that have a disproportionate impact on people of color, particularly the harsh sentencing laws he pushed as an ALEC member.

Given its fragile and unusually rich ecology, the Hawaiian island of Kaua'i seems ill-suited as a site for agricultural experiments that use heavy amounts of toxic chemicals. But four transnational corporations -- Syngenta, BASF Plant Science, DuPont Pioneer, and Dow AgroSciences -- have been doing just those kinds of experiments here for about two decades, extensively spraying pesticides on their GMO test fields. As a result, the landscape on the southwest corner of the island has become one of the most toxic chemical environments in all of American agriculture.
