A group of New York bikers has set out to save the environment by starting a bike-powered composting service. They collect food waste from restaurants and households for composting, and then use that compost as fertilizer to grow vegetables. In a city with a population of 8.5 million people, this might seem like a drop in the bucket, but while the scope might be small now, the organizers have big and green plans for the project. Nina Vishneva has the story narrated by Anna Rice.
