Green eco is one of the six types of eco in the Jak and Daxter series, and one of the four colored eco components that make up light eco. It is a regenerative eco, supplying health to life. It also acts as a limited reversal to effects of dark eco, especially in plant life. The sage of green eco is Samos Hagai, and is used throughout the series as a means of restoring health, and occasionally as fuel. It is also considered the eco of nature, allowing Samos Hagai to communicate with plants and rocks.
