"Environmental Bill of Rights"

"In 1970, the legislature passed an "Environmental Bill of Rights" which stated that "the people have a right to clean air, [and] pure water…." Simultaneously, the national government established the Environmental Protection Agency, and Congress passed the Clean Air Act. A few years later, Pennsylvania established the Department of Environmental Resources, one of the prominent objectives of which was "to ensure future generations of Commonwealth residents a quality environment." This function is carried on today by the Department of Environmental Protection. "
