This video shows what a group hug for the ages looks like: a world-record 250,000 young people who joined arms, hearts and voices at World Youth Day in Panama to launch the Laudato Si’ Generation. LSG is a new global youth movement that works faithfully and prayerfully for climate justice. Guided by the Holy Spirit, and inspired by Pope Francis, these young Catholics have responded as never before to the climate crisis. Their numbers and energy have breathed new life into the environmental movement as they pray, march and care for Creation. Their voice matters and so does yours! Sign this letter now and tell older generations that it’s time for change.
