Earth Hour 2013 goes beyond the hour
More than 7,000 cities and municipalities in 154 countries and territories participated in WWF’s Earth Hour 2013, which was supported by celebrities such as Barcelona football star Lionel Messi, astronaut Chris Hadfield (from the International Space Station) and anti-Apartheid hero Nelson Mandela, in another record-breaking sweep around the planet. Many of the world’s best known human and natural landmarks went
dark including for the first time the Kremlin and Red Square in Russia.
Earth Hour was boosted this year by many examples of conservation challenges and action beyond the hour. The social media around Earth Hour 2013 was the biggest ever, with a 50 per cent increase in tweets to 1.16 million.
