Earth Hour is the world's largest environmental grassroots movement, inspiring millions of people to take action for our planet and nature. It started in Sydney, Australia, as a lights-out event in 2007 and has continued to grow. In 2022, 192 countries participated in Earth Hour, raising awareness about various environmental issues. Global landmarks such as the Sydney Opera House, the Colosseum in Rome, the Eiffel Tower in Paris, and the Empire State Building in New York City took part by symbolically switching off lights to support the movement. In Namibia, we took the idea of Earth Hour to the next level by using it to actively include the youth in conservation. WWF Namibia and partners in the Namibian Association of CBNRM Support Organisations (NACSO) reached out to 57 young adults from the Kunene North and South, North Central, and the Zambezi regions, representing 23 communal conservancies. While the initial activities were associated with Earth Hour events, the positive response from these young people has presented an opportunity to grow a youth movement for conservation in Namibia.
