Haifa al Mansour has become Saudi Arabia's first female film director after making a film about a Saudi girl who wants a bicycle. Haifa al Mansour has faced much pressure to quit and criticism of her career choice in the country that only shows a few films publicly and has tight restrictions on women's freedoms.

In its first such action, the U.S. Environmental Protection Agency (EPA) shut down heavy industries in Birmingham, Alabama, when air pollution on this day was reaching dangerous levels. It was an emergency action under the Clean Air Act (1970). The EPA asked a Federal judge to issue a temporary restraining order. Among others, U.S. Steel had been belching too much smoke into an atmospheric inversion (stagnant air mass). Among idled workers, one said, “we're going to choke to death before we starve to death.” Six months before, the city had suffered a five-day crisis that spiked on 20 Apr 1971. At that time, while the state failed in enforcement, the EPA was not notified early enough to start emergency action. Days with high particulate counts in the air thereafter drew close EPA scrutiny.
