**What Gross Primary Productivity Is and Why It’s Shaping Conversations Across the US** Ever wondered what drives the earth’s natural energy capacity—on a global scale? Gross Primary Productivity (GPP) is a metric that measures how much energy plants, algae, and certain microorganisms capture from sunlight and convert into organic material through photosynthesis. It’s a foundational indicator of global ecosystem health and a silent driver behind climate patterns, food security, and renewable energy potential. Increasingly, experts, policymakers, and innovators are turning to GPP to understand sustainability and environmental resilience in a world focused on measurable, natural processes. Why is GPP gaining traction now? In the US, rising concerns about climate change, agricultural efficiency, and the future of clean energy are fueling deeper interest. As renewable energy projects expand, accurately tracking GPP helps model carbon cycles, predict crop yields, and assess ecosystem recovery. This growing relevance makes GPP a key term at the intersection of science, policy, and economic planning. ### How Gross Primary Productivity Actually Works
