The History of Earth Day

Earth day is an annual event celebrating the achievements of the environmental movement and raising awareness to the importance of ecological sustainability for long-term human stability. April 22nd, 1970, marks the first Earth Day in history, which mobilized 20 million Americans across the continent. Today, it’s estimated that 1 billion people participate, making Earth Day the largest secular movement in the world. In this two-part series, we first look at the history of Earth Day and how it’s celebrated across the globe. In Part 2, we’ll review more history and how Earth Day has transformed with changing trends – namely, political shifts, environmental activism, climate change awareness and social diversity and inclusivity. You’ll also be provided with Earth Day resources to help you participate on this special day.

The history of Earth Day and how it’s celebrated across the globe

Rachel Carson’s Silent Spring came as a watershed moment in how we view the planet and our impact on it. The book renounced the sinister degradation of our natural world by mass chemical pesticide and insecticide use. Carson describes chemical pest control as a poisonous agricultural ooze, stifling life and bird song from our springs.

Published in 1962, Silent Spring sold more than 500,000 copies in 24 countries and kick-started the environmental movement. This movement demanded a shift in perspective, where nature was no longer seen as something to be controlled for man’s convenience, but rather as a connected part, essential for human development and stability.

Inspired by Carson’s work, American politician and environmentalist Senator Gaylord Nelson, targeted an already emerging public consciousness around air and water pollution. In 1969, Nelson delivered a series of lectures and discussions on college campuses to educate towards the goal of reducing humanity’s impact on our planet.

April 22nd was the date chosen for these college teach-ins. As a weekday falling between spring break and final exams, this date maximized student participation. To help him with his quest, Nelson recruited young activist Denis Hayes and conservation-minded Republican Congressman Pete McCloskey. Hayes soon recognized the potential to expand the reach of these teach-ins and inspire all Americans. As such, the team grew and promoted events across the continent. The day was renamed Earth Day, a marketing move that attracted a lot of media attention.
