    Twelve-year-old Kiké Dueck once had such bad climate anxiety that they didn't want to eat or go to school. But then they found a solution. Kiké got involved in lobbying Regina city hall for greener transit and even joined a legal case to try to stop Saskatchewan's support of coal plants. Kiké is not the only child taking the government to task - and to court. In fact, Kiké is part of a group led by What On Earth's mental health columnist, Abhay Singh Sachal, that teaches young people how to understand their emotions about climate change and channel them into organized activism and community action.
