United Nations reminds all citizens of Earth Hour 2011, 26 March, 8:30 p.m.
This Saturday night, 26 March, Earth Hour 2011 will be observed — and the United Nations is once again participating. This involves turning off non-essential lights from 8:30-9:30 p.m. local time. Hundreds of millions of people in 128 countries participated in the event last year, making it one of the largest public awareness- raising events in the world. Scheduling the event right after the vernal equinox, 8:30 p.m. ensures that it will be dark in both the southern and northern hemispheres at the same time.
The purpose of Earth Hour, which is organized by the international environment NGO WWF, is to raise awareness about climate change and the need to use energy more efficiently.
At the UN Headquarters in New York, they will be turning off lights for the Hour, and field offices will also participate.
