"This is not about making money, it's really about raising awareness about sustainability," said Melissa Farrar, spokeswoman at the Fairmont in San Francisco. "There's not one solution so we wanted to do our part to help. It's part of the bigger effort for helping the planet."

Farrar said the four hives on the rooftop garden support about 250,000 bees and produce about 1,000 pounds of honey each year.

The Fairmont Hotel is discussed starting at 1:55.
