The 3rd Annual Green Brooklyn Conference is taking place today at Brooklyn Borough Hall from 11AM-4PM. Coordinated by Brooklyn Center for the Urban Environment, it’s billed as “Brooklyn’s largest showcase of green and sustainability issues, programs, and products.” The even is a fully day fair and symposium and “will feature workshops and discussions led by several of the city’s preeminent leaders in sustainable design, green manufacturing, transportation alternatives, energy efficiency, environmental education, and sustainable food.” The full schedule is available here. We’re intrigued by the “hands-on worm composting demo” from 2:45-3:30. You simply can’t get that kind of thing every day.
