This day of nature's equipoise was later sanctioned in a proclamation written by McConnell and signed by Secretary General U Thant at the United Nations. A month later a separate Earth Day was founded by United States Senator Gaylord Nelson as an environmental teach-in first held on April 22, 1970. Nelson was later awarded the Presidential Medal of Freedom award in recognition of his work.

The National Football League Draft, also called the Player Selection Meeting, is an annual event in which the National Football League (NFL) teams select eligible college football players. It serves as the league's most common source of player recruitment. The basic design of the draft is that each team is given a position in the drafting order in reverse order relative to its record in the previous year, which means that the last place team is positioned first. From this position, the team can either select a player or trade their position to another team for other draft positions, a player or players, or any combination thereof. The round is complete when each team has either selected a player or traded its draft position. Certain aspects of the draft, including team positioning and the number of rounds in the draft, have seen revisions since its first creation in 1936, but the fundamental methodology has remained the same. Currently the draft consists of seven rounds. The original rationale in creating the draft was to increase the competitive parity between the teams as the worst team would, ideally, have chosen the best player available.
