Commoner's activist career can be defined as an attempt to weave together a larger vision of social justice. Since the 1960s, he has called attention to parallels between the environmental, civil rights, labor, and peace movements, and connected environmental decline with poverty, injustice, exploitation, and war, arguing that the root cause of environmental problems was the American economic system and its manifestations.
