?As long as we grow in open fields, the risk of contaminating the food supply is great, said attorney Paul Achitoff with Earth Justice.

The Honolulu-based nonprofit, environmental law firm documented genetic engineering in Hawaii.

They say, right now, there are 15 species of weeds resistant to Roundup, and that's led to more and stronger pesticide use.

150 Kauai farmers sued biotech company Pioneer in December. The suit claims Pioneer uses pesticides on its test crops almost every day - combined with trade winds, kicking up pesticide-filled dirt that blankets Waimea.

Pioneer says it's done everything from growing vegetation shields to slowing traffic but says: ?Living with some dust is a reality of life on Kauai."

?How come all of a sudden now? I mean it's not just the seed farmers. That is a farming community. How come all of a sudden now?? said Maluafiti.

?I think right now there are so many unknowns,? said Cochran.

In Hawaii, the cultural fears over GMO taro caused protesters to lock the doors on UH researchers.

And, twice, in the past year, vandals chopped down scores of trees believed to be GMO papayas on the Big Island.

?I hope we can move in a positive direction here,? said Cochran.
