Greta Thunberg marches in Montreal for global climate protests

The 16-year-old Swede met privately with Trudeau but later told a news conference with local indigenous leaders that he was "not doing enough" to curb greenhouse gases responsible for global warming. Thunberg generated headlines around the world earlier this week with her viral so-called "How Dare You?" speech at the UN climate summit, accusing world leaders of betraying her generation.
