The Russian invasion of Ukraine has destroyed so much -- including hundreds of schools, where the country's children were forging their futures -- but it has not stopped Ukrainians from pursuing knowledge and curiosity. In a deeply moving talk, education leader Zoya Lytvyn shares her first-hand experience evacuating Kyiv and takes us inside the ongoing effort to continue educating children amid war and destruction. "As long as our children keep learning and our teachers keep teaching -- even while they are starving in shelters under bombardment, even in refugee camps -- we are undefeated," she says.
