Nick S. was looking for a way to illustrate many ecological principals in as small a space as possible. Inspired by the rooftop farm system at the Brooklyn Grange, Randall's Island Park now has its own O2Compost system. It is used to compost crop residue and food waste. The finished compost is going back onto the vegetable beds, and serves as an educational tool to teach young students the importance of composting and how nutrients can be recycled in our food system.
