Bill McKibben, a climate activist, speaks to a group of students at the Hilltop Montessori School, in Brattleboro, Vt. The Keystone XL is dead after a 12-year attempt to complete the partially built oil pipeline. But the fight over Canadian crude rages on as emboldened environmentalists target other projects and pressure President Joe Biden to intervene. McKibben, an author who was arrested outside the White House while protesting the Keystone XL in 2011, said its defeat provides a template to kill other pipelines, including Line 3 and the Dakota Access Pipeline from North Dakota's Bakken oil field.
