In the time span between pre-European settlement to the present, the United States has lost approximately 50% of its wetlands. option 3 is correct
Step-by-step explanation:
In the time span between pre-European settlement to the present, the United States has lost approximately 50% of its wetlands. This dramatic loss of wetlands is attributed to a variety of human activities, including clearing land for agriculture and development, which have been major causes of habitat destruction.
Particularly concerning is the fact that, within the past 100 years, the amount of land used for agriculture has nearly doubled, and land used for grazing has more than doubled, contributing significantly to the reduction of wetland areas. Wetlands are essential due to their role as habitats for a wide array of species and their function in filtering pollutants, making their preservation and restoration critical for maintaining biodiversity and environmental quality.
