Question

how do humans benefit directly from wetlands?
wetlands are not important to humans.
wetlands filter out pollutants and help clean freshwater.
wetlands could disappear tomorrow and nothing would change

Explanation:

The first and third options are incorrect because wetlands are ecologically and practically vital to humans, so their loss would cause significant harm. The second option describes a direct, tangible benefit: clean freshwater is essential for human drinking, agriculture, and daily use, and wetlands' pollutant-filtering function directly supports this.

Answer:

Wetlands filter out pollutants and help clean freshwater.
