Environmental activist group Extinction Rebellion (XR) is organising a huge, ongoing 'action' outside the Houses of Parliament later this spring.
'The Big One', as it's being dubbed, is scheduled to begin on 21 April 2023, and it's hoped that at least 100,000 people will take part — the number of signatures needed on a petition to get it raised in Parliament. There's no petition involved here (Extinction Rebellion claims that "petitions have never worked for issues around the Climate & Biodiversity crises") but it's thought that having that number of people visible outside Parliament will put pressure on MPs.

On 11 January, the 100-day countdown to the event began, with the group unveiling banners on major landmarks across the UK in a bid to build momentum. Extinction Rebellion has a huge marketing campaign planned, so expect to hear plenty more about The Big One in coming weeks, including the release of a full strategy document.
It's part of a change in tactics from the group better-known for its disruptive protests that block major roads and transport networks. XR claims that so many people are now concerned about the environment, they have enough support for peaceful action to be effective. That said, some will argue that XR have realised that the more disruptive action is sometimes alienating public support, and so it's trying a change of tack.
What is 'The Big One'?

The "biggest mobilisation campaign XR has ever undertaken" is how XR describes The Big One, which it is keen to point out is a "nonviolent, direct action", rather than a march, protest or rally. No paint will be thrown, and no glue will be used to stick people to roads or vehicles.
Instead, people will sit peacefully outside Parliament in huge numbers — as we say, XR hopes at least 100,000 — taking up residence day after day from 21 April, in a bid to get the attention of those in power working in Parliament.
What do Extinction Rebellion hope to achieve?
We must build bridges & come together to unite to survive. People are crying out for change. Change will happen with all of us, standing together to challenge power and demand a better tomorrow.

Ultimately, Extinction Rebellion wants to trigger policy change, to end the use of fossil fuels in this country, to get politicians and those in power to take threats to the climate and the environment more seriously, and to move towards a future democracy which is citizen-led, rather than having decisions which affect the many made by the few in power.
It's hoped that by showing just how many members of the public support this, MPs will be pressured into taking action.
