Twenty-five years ago, the Union of Concerned Scientists and more than 1,700 independent scientists, including the majority of living Nobel Prize laureates in the sciences, penned the 1992 “World Scientists’ Warning to Humanity.”These concerned professionals called on humankind to curtail environmental destruction and cautioned that “a great change in our stewardship of the Earth and the life on it is required, if vast human misery is to be avoided.” In their manifesto, they showed that humans were on a collision course with the natural world.
