The first people Greta convinced to take action on climate change were her operasinger mother Malena Ernman, who gave up air travel, and her actor father Svante Thunberg, who turned vegetarian. Since then, she has addressed political and business leaders, and met the Pope. Arnold Schwarzenegger said he was ‘star-struck’ when he met her last month (above).
