A geographer uses GIS data showing that a coastal wetland shrinks by 4% annually due to climate change and an additional 30 acres per year from infrastructure development. If the wetland started at 800 acres, how large will it be after 2 years?

**How a Changing Coastline Reveals Urgent Environmental Shifts—And What It Means for Communities** How are coastal wetlands—vital natural buffers defending US shorelines—faring under pressure from both climate change and development? According to recent GIS-based analysis, a 800-acre coastal wetland shrank by 4% each year due to rising sea levels and extreme weather, while 30 acres vanish annually from expanding infrastructure. This dual threat paints a clear picture of change—and urgency—across vulnerable shorelines nationwide. For people tracking coastal resilience, understanding these trends is more than academic: it informs informed decisions about land use, protection, and future planning. **Why This Trend Is Gaining Moment Across the US** With coastal habitats under dual stress from ecological and human-driven forces, interest in data-driven insights about wetlands is growing fast. More Americans are seeking reliable, spatial information to understand environmental loss beyond headlines—whether for community advocacy, policy engagement, or personal awareness. Satellite mapping technologies now deliver precise, near real-time tracking, turning complex geographic data into accessible insights. The shrinking of wetlands like this one is not isolated; it reflects national patterns where climate impacts and development pressures increasingly intersect, demanding clear public understanding.
