This Sunday, the Mayor will formally unveil more PlaNYC details (though the website has been up for a while now). He'll give the speech at the American Museum of Natural History, to which New York Mag says, "while we're excited to see the plan, we confess the museum's symbolism is making us nervous: dinosaurs … carcasses … oy."

2007_04_arts_earth.gifMUSIC: Celebrate the earth with some tunes this weekend at the Green Apple Music Festival. Musicians will be playing all over the city and will include everyone from Taylor Hicks (remember Soul Patrol?), Dave Matthews, Jon Anderson (singer of the band Yes), Charlie Hunter, School of Rock, Brand New and many more.

The festival events will also provide relevant information on the environment and the 25 clubs will be filled with eco-friendly items. Organizer Peter Shapiro says, "We're giving to all the venues recycled content, cups, napkins, straws, garbage bags. So we're going to green the venues, give the venues a chance to see that being green isn't difficult."

Earth Day at Grand Central will also be a part of the Green Apple Festival, with concerts free and open to the public.

All Weekend // Various Times and Venues // Full Schedule Here

SHOPPING: The longstanding Hell's Kitchen Flea Market will go green this weekend. The sustainable landscape in its own right will hold an outdoor bazaar welcoming eco-friendly and socially conscious companies to its already colorful sidewalks.

The market will also be erasing “carbon footprints” (even at its Manhattan sister markets The Garage and The Annex at 25th Street), thanks to Carbon Fund. Carbon Fund "provides an online trip calculator that tells you how much carbon emission is produced via traveling by car, by plane and household energy consumption offering tangible ways to offset your carbon credits."

Saturday and Sunday // 10am to 6pm // 39th Street between 9th & 10th Avenues

TV: Check out Sundance Channel's new block of programming dedicated to the environment. It's called The Green. The schedule is here, and upcoming episodes include: Fuel, Build, Furnish, Cities and more.

SAVE THE DATE: "Green Apple Talk #3: Environmentalism Now" will explore "how far the movement has come since the first Earth Day nearly forty years ago. What will the next wave of green culture look like, and how can the individual decisions consumers make have a global impact?"

The event will feature Ramon Cruz (policy analyst for Environmental Defense), Emily Gertz (environmental journalist and co-author of WorldChanging: A User's Guide to the 21st Century), Aaron Naparstek (Transportation Alternatives and StreetsBlog.org), Anne-Marie Van Dijk (model and supporter of the Whale and Dolphin Conservation Society, Orca Network and Natural Resources Defense Council) and more. The discussion will be moderated by best-selling author Bryan Keefer.
