Ancient Hawaiian Farmers Offer Lessons in SustainabilityThousands of government officials, environmental activists, business leaders and other delegates from nearly 200 countries are in Honolulu for 10 days to shape the direction of global conservation and sustainable development. This is the first time the eco-summit is being held in the U.S. Organizers say one of the reasons the Aloha state was chosen to host the quadrennial conference is because it’s been a model for incorporating indigenous culture into its conservation initiatives. A shining example of this is Limahuli Garden and Preserve, on the island of Kauai.
