Global Warming has been increasing every day; this is the step towards making this world a better place by reducing emissions of gasses and all other man-made causes which can worsen climatic conditions.
It is the ninth anniversary of the Earth hour and the whole world will be be dark on Saturday at 8:30 pm GMT.
Ban Ki-moon, the UN secretary general said, “Earth hour shows what is possible when we unite in support of a cause: no individual action is too small, no collective vision is too big. This is the time to use your power.”
More than 7,000 cities across 172 countries will be taking part in it.
UN building and London’s house of parliament will also go dark during the Earth hour.
By switching off lights, we are highlighting billions of people who still live in dark and requires access to affordable, sustainable and clean energy for their well-being, Ban added.
