History

Historical Context

The Air Pollution Control Act of 1970 marked a pivotal moment in U.S. environmental policy, establishing federal air quality standards amid rising pollution concerns since the 1940s. The creation of the Environmental Protection Agency (EPA) facilitated a 30% reduction in airborne pollutants by 1990. Today, similar challenges persist globally, as seen in India's Northeast, where PM2.5 levels exceed safety standards, underscoring the need for effective governance.
