The environmental classes work hard in order to make Glen Rock High School a more environmentally friendly place. Their primary concern currently is self sustainability. This is achieved through their composting program. They collect fruit scraps and various products people throw into the garbage. This it is then put into large black bins where it decomposes into soil. After this, the compost is dried out and used as fertilizer to grow the garden in the courtyard as well as some plants in the greenhouse. Some of the food from the garden is then used to feed the chickens which lay eggs. The environmental class then uses these eggs to cook food, like pancakes.
