Question

what is the purpose of the clean water act? to promote deforestation to lower wood prices to control discharges of pollutants into u.s. waters to regulate international agricultural practices

Explanation:

The Clean Water Act is a U.S. law focused on water - related environmental protection. It aims to safeguard water quality. Controlling pollutant discharges into U.S. waters is a key environmental protection measure. Deforestation promotion (first option) is contrary to environmental goals. Regulating international agricultural practices (third option) is not the main scope of the Clean Water Act which is mainly about U.S. water pollution control.

Answer:

to control discharges of pollutants into U.S. waters
