Tomorrow's Earth

Abstract

Our planet is in a perilous state. The combined effects of climate change, pollution, and loss of biodiversity are putting our health and well-being at risk. Given that human actions are largely responsible for these global problems, humanity must now nudge Earth onto a trajectory toward a more stable, harmonious state. Many of the challenges are daunting, but solutions can be found. In this issue of Science , we launch a series of monthly articles that call attention to some of the choices we can still make for shaping tomorrow's Earth—commentaries and analyses that will hopefully provoke us to making thoughtful choices (see scim.ag/TomorrowsEarth ).
