VOICED : Hora del Planeta oscurece grandes ciudades por desafio climatico

Earth Hour is a global initiative started in 2007 to raise awareness about climate change by turning off lights for 60 minutes. Originating in Australia, it now involves millions across 187 countries. This year's focus is on the impact of climate change on biodiversity. The campaign has led to successes like banning plastic in the Galápagos and planting trees in Kazakhstan.
