Patrick Rudd, a 15-year-old student in Port Macquarie, New South Wales, strikes about once a month -- and he always takes this sign with him. “I’ve been part of the climate strike since I heard about Greta Thunberg sitting outside her parliament,” he says.
Rudd wants to see global carbon emissions halved by 2030. “We need radical action and we need it now. We need governments to call it what it is -- a climate emergency.”
