As Greta Thunberg says, “We cannot solve an emergency without treating it like an emergency.” We have to “act as if the house is on fire, because it is.” That does not mean we simply need a New Deal painted green, or a Marshall Plan with solar panels. We need changes of a different quality and character. A new vision of what humanity can be is emerging. It is coming from the streets, from the schools, from workplaces, and even from inside houses of government. When the future of life is at stake, there is nothing we cannot achieve.
