Swedish teenager Greta Thunberg became famous this spring for launching a student movement to compel adults to take action on climate change. Instead of going to school, Greta has been spending her Fridays in front of the Swedish parliament with a sign reading: “School Strike for Climate.” Students in more than 70 countries have since followed her lead. But before she started trying to convince the world to take action, Thunberg worked on her parents. She showered them with facts and showed them documentaries. “After a while, they started listening to what I actually said,” Thunberg told the Guardian newspaper. “That’s when I realized I could make a difference.”
