Students Walk Out Of School As Part Of Worldwide Youth Climate Strike

SAN FRANCISCO, CALIFORNIA – MARCH 15: Students carry signs as they march during the Youth Climate Strike on March 15, 2019 in San Francisco, California. Hundreds of thousands of students in more than 100 countries walked out of class on Friday for the Youth Climate Strike to raise awareness to global warming and many governments failure to address it. The worldwide protests were inspired by 16-year-old Swedish activist Greta Thunberg, who started staging solo protests outside of the Swedish Parliament last year.
