Which was a result of both the Clean Air Act and the Clean Water Act?

A. increased paper recycling
B. reduced car emissions
C. increased plastic recycling
D. reduced factory pollution

D. reduced factory pollution

The answer is D. reduced factory pollution. Both the Clean Air Act and the Clean Water Act were implemented to regulate and reduce pollution from various sources, including factories. These acts set standards and regulations to control emissions and discharges that can harm air and water quality.

The correct answer is D. reduced factory pollution. Both the Clean Air Act and the Clean Water Act aimed to protect environmental quality by reducing pollution. The Clean Air Act was enacted in 1970 and focuses on improving air quality by setting emission standards for industries, power plants, and motor vehicles. It has resulted in reduced car emissions due to the mandatory use of catalytic converters in vehicles and the implementation of stricter emission standards.

The Clean Water Act, passed in 1972, aims to protect and restore the quality of water bodies in the United States. It establishes pollution control programs, sets wastewater standards, and regulates the discharge of pollutants from various sources, including factories. As a result, factories are required to implement measures to reduce pollution and ensure the wastewater they generate is treated before being released into water bodies.

Both acts have had a significant impact on reducing pollution, but in this case, the Clean Air Act specifically addresses car emissions, while the Clean Water Act targets factory pollution. Therefore, the correct answer is D. reduced factory pollution.
