Earth Hour 2010

On March 27, 2010, from 8:30 P.M. to 9:30 P.M., cities and towns across the world will switch off their lights for one hour — Earth Hour — sending a powerful global message that it’s time to take action on climate change. Earth Hour 2010 aims to empower individuals, communities, businesses, and governments to commit to the challenge of solving the climate change crisis.

Last year, the Philippines ranked first in terms of scope of public participation, with 647 cities and towns switching off their lights. This year, the Philippines once again joins over one billion people in more than 6,000 cities and towns worldwide in this symbolic act of switching off lights.
