Every spring, chlorophyll returns to center stage. Tiny green molecules fill leaves and needles, capturing sunlight and powering photosynthesis—the remarkable process that feeds nearly all life on Earth. Without chlorophyll, there would be no forests, no abundant oxygen, and no thriving ecosystems. But chlorophyll may be doing something else that is less obvious. The living green it creates appears to benefit us, too. Scientists have long known that forests improve our physic

Most people can identify a robin or a deer at a glance, yet walk past dozens of trees without noticing them. Scientists call this tendency to overlook plants as active living organisms plant blindness. Our brains often treat trees as scenery rather than as living systems that breathe, communicate and defend themselves, support wildlife, and respond to environmental change. Seeing trees as background objects affects public support for tree protection and urban forestry, since

For much of modern history, forests have often been viewed through an economic lens. Trees become board feet of lumber, sources of pulp, fuel, or land to be cleared for development. While these uses are real and sometimes necessary, they can obscure a more fundamental truth: forests are living communities upon which all life—including our own—depends. Many Indigenous cultures throughout North America have long held a different perspective. Trees, animals, rivers, and even the
