Earth Hour 2021: Global Virtual Event

Earth Hour is one of the largest global grassroots movement for the environment, and will bring together millions of people, businesses and leaders from around the world who will shine a spotlight on the urgent need to address nature loss and climate change.

“The Earth Hour movement has been celebrated in South Africa – and the world over – for more than a decade. This year, we have an incredible opportunity to join hands as citizens of the world during a global virtual event. We are calling on our supporters to shine a spotlight on some of the most pressing environmental issues of the day by signing up as a ‘nature hero’ for the hour,” says Dr Morné du Plessis, CEO of WWF South Africa.

Uniting online and speaking up for nature 

On the night of Earth Hour, WWF South Africa will share a special Earth Hour 2021 campaign video narrated by the multi-award-winning actor, director and playwright Dr John Kani and encourage participants to share this on their social media platforms. This video shows the links between pandemics, climate change and pollution, and the role of nature in addressing these challenges.

2021 is a critical year for nature

The theme for Earth Hour 2021 focuses on “Climate Change to Save Earth”. This year, key political decisions will be taken by world leaders which will set the course of our future. These decisions will affect the health of our planet and our own future for decades to come. Several catastrophic incidents last year, including extreme weather events, devastating wildfires and the Covid-19 outbreak, proved that preventing nature loss is imperative for safeguarding our future.

Earth Hour is a critical moment for individuals, leaders, and environmentalists to unite and call for urgent action to reverse nature loss and secure a nature-positive world by 2030.
