In the 1960s, there were many environmental pollution incidents in the United States. Two Americans, Nielsen and Hayes, worried about environmental issues, held a civil activity on the theme of environmental protection in the spring of 1970. Unexpectedly, the event was positively responded by the American people, and about 20 million people participated in it. The momentum was very large. This day is April 22, which is the later Earth Day.
