If Science Is to Save Us

Understanding science is crucial for the future of humanity, writes astrophysicist Rees (On the Future: Prospects for Humanity) in this solid treatise. Rees opens by identifying three “interlinked mega-challenges” humanity will face in the very near future: providing enough food and energy for a growing population while avoiding further damage to the climate; facing the “ethical conundrums” posed by biotechnology; and enabling artificial intelligence to “transform our economy and our society, despite vulnerability to malfunctions.” More bluntly, “the whole future of our species depends” upon science being deployed “for social benefit,” Rees argues, and, as such, scientists must play a part in public policy and experts should be “embedded in the government at a high level.” To that end, Rees examines how to get “the best from science,” contending that, among other things, the field “needs ambitious and stable funding” and K–12 teachers should be paid higher salaries. Ultimately, Rees writes, “we need a scientifically aware public energized and inspired by charismatic campaigners.” His reasoning is sensible and down-to-earth, and the call for change refreshingly urgent instead of doom and gloom. The result is a convincing study on why “science isn’t just for scientists.” (Dec.)
