Since colonial times, the U.S. has lost over approximately what percentage of its wetlands?

The correct response indicates that the U.S. has lost approximately 50% of its wetlands since colonial times. This significant loss is primarily attributed to factors such as urbanization, agriculture, and infrastructure development. Historically, wetlands have been drained for farming, filled for developments, and otherwise altered to accommodate growing populations and economic needs.

Understanding the implications of this loss is crucial, as wetlands provide essential benefits such as flood protection, water quality improvement, and habitats for wildlife. Recognizing the extent of wetland loss emphasizes the importance of conservation efforts and the protection of remaining wetlands. The statistic serves as a stark reminder of the environmental impact of human activity and the necessity for policies that promote wetland restoration and preservation.
