"Our House Is on Fire": Greta Thunberg Addresses Hundreds of Thousands at NYC Climate Strike

Sixteen-year-old Swedish activist Greta Thunberg spoke at Friday's climate strike in New York, where an estimated 300,000 people took to the streets. Thunberg inspired the global spread of weekly climate strikes when she started skipping school to protest outside of the Swedish parliament last year. "We will not just stand aside and watch," Thunberg told a crowd of thousands in her speech at Manhattan's Battery Park. "We are united behind the science, and we will do everything in our power to stop this crisis from getting worse."
