The Earthshot Prize was launched in 2020 by the Prince and Princess of Wales to recognize and reward projects that help protect the planet. It has five categories - 'the restoration and protection of nature', 'air cleanliness', 'ocean revival', 'waste-free living', and 'climate action'. These are inspired by the UN's sustainable development goals. Each Earthshot Prize winner will receive £1 million ($1.2 million) to help it grow. Watch to learn more about the Eartshot Prize winners.
