It's not particularly green-related, but it's too momentous not to mention (from the Washington Post):

WASHINGTON - The pace at which Americans are getting cancer has started to decline for the first time, marking what could be a long-awaited turning point in the battle against the disease, according to an annual report that tracks progress in the war on cancer.

Cancer deaths have also continued a decline that began in the early 1990s, meaning that for the first time both trend lines are dropping.

"It is a significant milestone," said Otis Brawley, chief medical officer at the American Cancer Society, which produces the report with the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries. "It is a really big deal."
