A 20,000-km walk from Africa to the Arctic Circle has started. The walk is called The Herds. It will raise awareness of the climate crisis and will take four months. The project includes hundreds of life-sized puppets of lions, zebras, monkeys, and other animals. Over 2,000 people will make more puppets, all from recyclable materials. The Herds organizers want to show how climate change is affecting animals. A spokesperson said: "The Herds is public art and climate action on [a huge] scale. It's an ambitious coming together of culture and climate."

The animal puppets will visit more than 20 cities across Africa and Europe, including Casablanca, Paris and London. The final event will be in August. Each city will host street performances. These will focus on how we can help Earth. The Global Rewilding Alliance said: "The Herds is going to reach millions of people and bring the…beauty of nature right onto the streets and into people's lives." Another environmental group said: "The Herds [represents] the twin crises of climate change and biodiversity loss, and the journey we must all make towards a brighter future."
