A fireplace with an open flue creates a sizeable hole in your house, allowing heat to escape in the winter and enter in the summer. Close the damper when you don't have a fire burning and save energy.
Do your part: An open fireplace damper can allow as much as 8 percent of the heat from your furnace to escape through the chimney.
Participation is pretty easy. By flipping off your light switch on March 27th at 8:30 p.m. local time you will be casting your vote for action on climate change.
Earth Hour started in 2007 in Sydney, Australia when 2.2 million homes and businesses turned their lights off for one hour to make their stand against climate change. Only a year later and Earth Hour had become a global sustainability movement with more than 50 million people across 35 countries participating. Global landmarks such as the Sydney Harbour Bridge, the CN Tower in Toronto, Rome’s Coliseum, and our very own Golden Gate Bridge all stood in darkness, as symbols of hope for a cause that grows more urgent by the hour.

FILL'ER UP: A freezer operates most efficiently when full. When a packed freezer is opened, there's less space for warm outside air to invade. If you don't keep enough food on hand to fill the space, make up the difference with water-filled plastic jugs.

Growing Biodiversity: Historically, humans have relied on 7,000 species of plants for food. Today, 90% of our diet is drawn from just 20 species. Organic grower Seeds of Change (www.seedsofchange.com) has undertaken the special mission of helping preserve heirloom and traditional flower, herb & vegetable varieties. Their efforts contribute to the maintenance of biodiversity, an essential element of conservation.
