Saturday March 28, 2009 – tomorrow – turn off your lights from 8:30 – 9:30 pm (your local time) as part of the international initiative, Earth Hour, to take a collective stand against Global Warming. As the website says, your light switch is your vote. By switching off the light for one hour it represents that you care about the climate and want to see changes and make changes. Join international landmarks, cities, and people across the world as they speak up for global sustainability. See last Friday’s post about Earth Hour for more details.
