On Earth Day, while many of my friends and colleagues don lab coats and hoist signs celebrating science in Washington, D.C., and around the world, I will not be joining them. It's not that I don't support the March for Science; I do. I hope that it will showcase scientists' passion and commitment to understanding Earth's diversity, creating knowledge that improves human welfare, and providing evidence for policymakers. I support my fellow scientists who are committing valuable time to march, and I wish I could join them. But while my colleagues march, I will be doing time-sensitive field research in the Colorado backcountry. Everyone must do their part to support science, and for me right now, that means getting out and doing it.
