The islands are several inches thick and feel like brillo pads. They contain a series of holes, evenly spaced out, where marsh grasses can be planted. Each one holds between 50 to 60 plants a piece. The idea is, once the islands are anchored, the plants will grow and the roots will eventually collect sediment-- helping build new land within six months to a year.However, an unusual idea is now planting itself here. Over the next several days, 300 volunteers will work to assemble and plant floating islands, which are made out of recycled plastic water bottles.
