Hawai’i is ground zero for GMO experimentation. The National Sierra Club has these policies:
CONCERNS WITH GMOS: WHAT IS THE SCIENCE?
Genetically modified organisms (GMOs) or genetically engineered (GE) foods have the potential to cause a variety of health problems. For example, they may produce new allergens and toxins, and spread harmful traits to non-GMO crops. In addition, at least one major environmental impact of genetic engineering has already reached critical proportions: overuse of herbicide-tolerant GE crops has spurred an increase in herbicide use and an epidemic of herbicide-resistant “superweeds,” which will lead to even more herbicide use. The long-term impacts of GMOs are unknown, and once released into the environment they cannot be recalled.
Even the loss of milkweed that Monarch butterflies depend on, (and other sources of nectar and pollen that wild pollinators require to survive) is an environmental side effect of intensive herbicide use associated with GE crops. Read more
We support the precautionary principle
When an activity potentially threatens human health or the environment, the proponent of the activity, rather than the public, should bear the burden of proof as to the harmlessness of the activity. Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing measures to prevent environmental degradation.
