#### 300The geographer observed that a coastal region has lost 12% of its wetlands every decade due to rising sea levels. If the region originally had 800 square kilometers of wetlands, how many square kilometers will remain after 30 years?

Sustainable Coastlines: How 30 Years of Wetland Loss Reshapes Coastal Ecosystems
(Including a detailed calculation: From 800 sq km to how much remains after 12% loss per decade) Coastal wetlands are vital ecosystems that provide natural flood protection, support biodiversity, and store significant amounts of carbon. Yet recent observations reveal a troubling trend: geographers studying coastal regions have documented a alarming 12% annual loss of wetlands due to accelerating sea-level rise. This environmental shift directly impacts both local communities and global climate resilience. ### The Decades-Long Decline: How Much Wetland Is Lost? A coastal region once spanning 800 square kilometers has been facing continuous habitat degradation—losing 12% of its wetlands every decade. Over 30 years, this erosion compounds significantly: three decades × 12% loss per decade = a total projected decline of 36% in wetland area.
