Designed as an environmental teach-in day, 20 million Americans participated in the original Earth Day -- with events in numerous communities and on school campuses.

Earth Day was marked in Los Angeles Wednesday by a host of antipollution programs and a notable absence of smog.

Some 60 students at Miraleste High School in Palos Verdes observed Earth Day by arriving at school on horseback instead of driving their cars.
Daylong programs were held at USC, UCLA, Caltech, San Fernando Valley State College, Cal Poly, UC. Irvine, Pasadena City College and others…
Santa Monica High School students donned surgical masks and ceremoniously buried an automobile engine. Other engines were buried on a number of campuses, including at USC, where the Tommy Trojan statue wore a gas mask.
Since 1970, Earth Day has been celebrated every year. The Earth Day Network now coordinates the international observance.
