A 20,000-km walk from Congo to Norway has started. It is called The Herds. It will teach people about the climate crisis. Hundreds of life-sized puppets of animals are on the walk. The Herds will show how climate change is a danger to animals. A spokesperson said The Herds is a "coming together of culture and climate".

The animal puppets will visit 20 cities in Africa and Europe. Each city will have street performances. These will focus on how we can help Earth. The Herds will teach millions of people about nature. An environmentalist says The Herds will teach people about climate change and biodiversity loss.
