On 24 October, people in 181 countries came together for the most widespread day of environmental action in the planet's history. At over 5200 events around the world, people gathered to call for strong action and bold leadership on the climate crisis.

Attendees of the Green New Deal Conference in Melbourne joined in to spell out '350' on the roof of the Economics & Commerce Building of Melbourne University.
