MANHATTAN — American youth are taking part in the Global Climate Strike, ahead of next week’s United Nations Climate Summit.

The march is also tied to the two-year anniversary of Hurricane Maria in Puerto Rico, and honors more than 4,500 lives lost.

Worldwide, the march is expected to draw millions in 150 countries, according to Vice News.

New York City’s all-day rally, organized by the Youth Climate Strike Coalition, is being held in lower Manhattan.

Those with parental consent were excused by the New York City’s Department of Education to miss school to attend the rally.

More than 100 climate strike participants were expected to come from Earth Matters Committee,  which is led by the Sisters of St. Joseph of Brentwood (L.I.), and by St. Joseph Workers and community partners.

Students from Sisters of St. Joseph-led high schools, including The Mary Louis Academy Jamaica Estates, and Fontbonne Hall Academy, Bay Ridge, were planning to go to the march in lower Manhattan.

Among the U.S. Youth Climate Strike Coalition’s demands include transitioning to a 100 percent clean, renewable economy by 2030, protecting indigenous lands and ending fossil fuel extractions.
