The environmental group, which was founded in the UK, has planned a large coordinated movement — called International Rebellion — in more than 60 global cities.
The biggest protests so far have been in Britain, where thousands of demonstrators have swarmed to sites around central London.
Hundreds of protesters have been arrested around the world so far as activists resist efforts by police to move them in the United States, Canada, Europe and Australia.
While their actions may vary, the international group of activists are united in their aims for governments to act immediately to stop biodiversity loss, "reduce greenhouse gas emissions to net zero by 2025" and be led by "the decisions of citizens' assemblies on climate and ecological justice."
