A movement of "Extinction Rebellion" protesters demanding rapid, deeper action to curb climate change has expanded around the world. Their hallmark is non-violent direct action out on the streets, often blocking roads and seats of government in major cities. The activists justify the disruption by saying an urgent response to an accelerating climate "emergency" is required to protect the planet for future generations.
