Thousands of people have blocked well-known landmarks including Waterloo Bridge in central London, bringing widespread disruption to the capital in a ???climate rebellion??? that organisers say could last several days.
Parents and their children joined scientists, teachers, long-term environmentalists and other protesters both young and old to occupy major junctions and demand urgent action over the escalating ecological crisis.
The protests are part of a global campaign organised by the British climate group Extinction Rebellion, with demonstrations planned in 80 cities across 33 countries in the coming days.
The group is calling on the UK government to reduce carbon emissions to zero by 2025 and establish a citizens??? assembly to devise an emergency plan of action to tackle climate breakdown and biodiversity loss.
