The 1970s was a decade of change -- regional and national politics, energy policy, environmental concerns -- that impacted the School's academics and research, the minerals industries, and graduates' job prospects. Mines continued to develop its humanities program and established a new environmental sciences program, although not without protest over impacts on the traditional technical curriculum. This was also a time of anxiety for what was still a culturally conservative institution, with the country experiencing civil disorder, the Viet Nam war, OPEC and the energy crisis, student protests, and the draft. The School weathered controversies over mandatory ROTC, objectionable content in the Oredigger student newspaper, freedom of expression, and the knowledge of sweeping college radicalism elsewhere. The School grew its resources as a residential campus. The number of women and ethnic minority students, while still a significant minority, continued to increase and further changed the face of Mines.
