It has been 52 years since the first Earth Day was celebrated in 1970 in Washington, D.C., and college campuses held rallies throughout America. It was a time of awakening. Many had said that Rachel Carson’s book, “Silent Spring,” which documented the adverse environmental effect caused by the indiscriminate use of pesticides, and the Santa Barbara oil spill in 1969, one of the largest oil spills in the U.S. at the time, killing over 3,500 birds and marine animals, were the catalysts for Earth Day.
