Text of my ‘When Worlds Collide’ column published in Ceylon Today Sunday newspaper on 25 March 2012
This year’s Earth Hour will be observed worldwide on Saturday 31 March 2012. That evening, millions of businesses and households will voluntarily switch off some or most night lights from 8.30 to 9.30 pm local time.
Earth Hour is an annual event to raise awareness on saving energy and taking personal action to mitigate climate change.
