Tonight, at 8:30 Sofia time, I’m switching off all the lights and plunging myself into darkness for 60 minutes, as part of Earth Hour. This year’s global hour of darkness, with a record participation by hundreds of millions of people in 150 countries and nearly 6,500 towns and cities, has already started in Oceania and Asia and will shortly make its way to and across Europe, before going on to the Americas. It’s a very simple and easy effort but one that has a huge impact, so just just go and do it! It’s tonight at 8:30pm local time, wherever you are.
