Thousands of people took to the streets of London on Monday morning in the midst of a week-long protest, blockading some of the UK capital’s busiest bridges and roads, to raise the alarm over a mounting climate crisis.

A group of demonstrators with trees, plants and solar panels in tow barricaded Waterloo Bridge, one of five locations being targeted by environmental campaigners in the city as part of the protest.

The demonstrations are part of a global campaign which demands governments “take decisive action on the climate and ecological emergency.
