However, green is a major component of the visible light spectrum, so combining algae that use green light with algae that use other wavelengths maximises the use of sunlight. Pigments appear the color of the reflected light, so the chlorophyll pigments do not use the green portion of the spectrum. Roxy, the leader of the project, will take you on a journey over the sea and show you that the most problematic facilities are the coal power plant and the fish farm.
