Today is the 40th anniversary of Dr. Martin Luther King Jr.'s assassination. Across the country, memorials and tributes will take place, people will intone sentiments of racial and social justice, and school children will be educated in the teachings of one of America's greatest historical figures.

Among those teachings, King's environmental vision is not likely to be the focus -- except for at The Dream Reborn, one of the largest MLK tributes in the nation. Held in Memphis, where Dr. King was killed on April 4th, 1968, The Dream Reborn lasts from today through Sunday, and is hosted by Green For All, a non-profit dedicated to environmental issues. Featuring leaders and visionaries on the green vanguard, the conference both celebrates Dr. King and addresses diverse green causes from resource development to sustainability and increasing the "green collar" workforce.

Aside from being in Memphis, the conference is sold out. So in lieu of attending in person, we offer this brief promotional video:
