Important eventsBack

Earth Day is an annual day on which events are held worldwide to demonstrate support for environmental protection. Earth Day is observed on April 22 each year. The April 22 date was designated as International Mother Earth Day by a consensus resolution adopted by the United Nations in 2009. Earth Day is now coordinated globally by the Earth Day Network, and is celebrated in more than 192 countries every year.

The name and concept of Earth Day was pioneered by John McConnell in 1969 at a UNESCO Conference in San Francisco. He proposed March 21, 1970, the first day of spring in the northern hemisphere. This day of nature's equipoise was later sanctioned in a Proclamation 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. While this April 22 Earth Day was focused on the United States, an organization launched by Denis Hayes, who was the original national coordinator in 1970, took it international in 1990 and organized events in 141 nations. Numerous communities celebrate Earth Week, an entire week of activities focused on environmental issues.


Wednesday, April 22, 1970 chosen as Earth Day

The genesis of Earth Day is credited to Gaylord Nelson, a U.S. Senator from Wisconsin. After witnessing the ravages of the 1969 Santa Barbara oil spill, and inspired by the student anti-war movement, he called for an environmental teach-in, later called "Earth Day", to be held on Wednesday, April 22, 1970. Over 20 million people participated that year, and now Earth Day is observed on April 22 each year by more than one billion people and many national governments in 192 countries. Earth Day appears on calendars around the world.

Nelson, an environmental and conservationist activist, hoped to demonstrate popular political support for an environmental agenda. He modeled it on the highly effective Vietnam War teach-ins of the time.

Nelson had conceived the idea for his environmental teach-in following a trip he took to Santa Barbara right after the horrific oil spill off the coast in 1969. Outraged by the devastation and Washington political inertia, Nelson proposed a national teach-in on the environment to be observed by every university campus in the U.S.

I am convinced that all we need to do to bring an overwhelming insistence of the new generation that we stem the tide of environmental disaster is to present the facts clearly and dramatically. To marshal such an effort, I am proposing a national teach-in on the crisis of the environment to be held next spring on every university campus across the Nation. The crisis is so imminent, in my opinion, that every university should set aside 1 day in the school year-the same day across the Nation-for the teach-in.

One of the organizers of the event said:

We're going to be focusing an enormous amount of public interest on a whole, wide range of environmental events, hopefully in such a manner that it's going to be drawing the interrelationships between them and, getting people to look at the whole thing as one consistent kind of picture, a picture of a society that's rapidly going in the wrong direction that has to be stopped and turned around.

It's going to be an enormous affair, I think. We have groups operating now in about 12,000 high schools, 2,000 colleges and universities and a couple of thousand other community groups. It's safe to say I think that the number of people who will be participating in one way or another is going to be ranging in the millions.

Nelson announced his idea for a nationwide teach-in day on the environment in a speech to a fledgling conservation group in Seattle on September 20, 1969, and then again six days later in Atlantic City to a meeting of the United Auto Workers. Nelson hoped that a grassroots outcry about environmental issues might prove to Washington, D.C. just how distressed Americans were in every constituency. Nelson invited Republican Representative Paul N "Pete" McCloskey to serve as his co-chair and they incorporated a new non-profit organization, Environmental Teach-In, Inc., to stimulate participation across the country. Both continued to give speeches plugging the event.

On September 29, 1969, in a long, front-page New York Times article, Gladwin Hill wrote:

Rising concern about the "environmental crisis" is sweeping the nation's campuses with an intensity that may be on its way to eclipsing student discontent over the war in Vietnam...a national day of observance of environmental problems, analogous to the mass demonstrations on Vietnam, is being planned for next spring, when a nationwide environmental "teach-in"...coordinated from the office of Senator Gaylord Nelson is planned.

Denis Hayes, a Harvard graduate student, read the NYT article and traveled to Washington to get involved. He had been student body president and a campus activist at Stanford University in McCloskey’s district and where Teach-In board member Paul Ehrlich was a professor. He thought he might be asked to organize Boston. Instead, Nelson eventually asked Hayes to drop out of Harvard, assemble a staff, and direct the effort to organize the United States. Hayes would go on to become a widely recognized environmental advocate.

Hayes recruited young college graduates to come to Washington, D.C. and began to plan what would become the first April 22 Earth Day.

The April 22, 1970, Earth Day marked the beginning of the modern environmental movement. Approximately 20 million Americans participated. Thousands of colleges and universities organized protests against the deterioration of the environment. Groups that had been fighting against oil spills, polluting factories and power plants, raw sewage, toxic dumps, pesticides, Freeway and expressway revolts, the loss of wilderness, and air pollution suddenly realized they shared common values.

Media coverage of the first April 22 Earth Day included a One-Hour Prime-time CBS News Special Report called "Earth Day: A Question of Survival", with correspondents reporting from a dozen major cities across the country, and narrated by Walter Cronkite (whose backdrop was the Earth Week Committee of Philadelphia's logo).

Pete Seeger was a keynote speaker and performer at the event held in Washington, D.C. Paul Newman and Ali MacGraw attended the event held in Manhattan.


Earth Day 1970 in New York City

In the winter of 1969-1970, a group of students met at Columbia University to hear Denis Hayes talk about his plans for Earth Day. Among the group were Fred Kent, Pete Grannis, and Kristin and William Hubbard. This New York group agreed to head up the New York City part of the national movement. Fred Kent took the lead in renting an office and recruiting volunteers. "The big break came when Mayor Lindsay agreed to shut down Fifth Avenue for the event. A giant cheer went up in the office on that day," according to Kristin Hubbard (now Kristin Alexandre). 'From that time on we used Mayor Lindsay's offices and even his staff. I was Speaker Coordinator but had tremendous help from Lindsay staffer Judith Crichton."

In addition to shutting down Fifth Avenue, Mayor John Lindsay made Central Park available for Earth Day. The crowd was estimated as more than one million—by far the largest in the nation. Since New York was also the home of NBC, CBS, ABC, the New York Times, Time, and Newsweek, it provided the best possible anchor for national coverage from their reporters all over the country.


Earth Day 1970 in Philadelphia

Earth Day 1970 in Philadelphia gave birth to Earth Week, April 16–22. It was created by a committee of students (mostly from University of Pennsylvania), professionals, leaders of grass roots organizations and businessmen concerned about the environment and inspired by Nelson’s call for a national environmental teach-in. The Earth Week Committee of Philadelphia concluded that devoting only one day to the environment would not provide enough time and space to paint a comprehensive picture of the environmental issues confronting mankind. While all of their activities would build toward a climactic Earth Day celebration on April 22, there would also be an entire week of events in the week preceding.

Austan Librach, a regional planning graduate student, assumed the role of committee chairman and hired Edward Furia, who had just received his City Planning and Law Degrees from University of Pennsylvania, to be Project Director. The core group from Penn was joined in 1970 by students from other area colleges which, working together, organized scores of educational activities, scientific symposia and major mass media events in the Delaware Valley Region in and around Philadelphia. The Earth Week Committee of 33 members settled on a common objective—to raise public awareness of environmental problems and their potential solutions.

U.S. Senator Edmund Muskie was the keynote speaker on Earth Day in Fairmount Park in Philadelphia. Other notable attendees included consumer protection activist and presidential candidate Ralph Nader; Landscape Architect Ian McHarg; Nobel prize-winning Harvard Biochemist, George Wald; U.S. Senate Minority Leader, Hugh Scott; and poet, Allen Ginsberg. Photos, video, and other previously unpublished information are available to the public at EarthWeek1970.org.


Results of Earth Day 1970

Earth Day proved popular in the United States and around the world. The first April 22 Earth Day had participants and celebrants in two thousand colleges and universities, roughly ten thousand primary and secondary schools, and hundreds of communities across the United States. More importantly, it "brought 20 million Americans out into the spring sunshine for peaceful demonstrations in favor of environmental reform."

Nelson stated that Earth Day "worked" because of the response at the grassroots level. Twenty-million demonstrators and thousands of schools and local communities participated. He directly credited the first Earth Day with persuading U.S. politicians that environmental legislation had a substantial, lasting constituency.

It now is observed in 192 countries, and coordinated by the nonprofit Earth Day Network, www.earthday.org, chaired by the first Earth Day 1970 organizer Denis Hayes,according to whom Earth Day is now "the largest secular holiday in the world, celebrated by more than a billion people every year." Environmental groups have sought to make Earth Day into a day of action which changes human behavior and provokes policy changes.


Earth Day 20 and Earth Day 1990

Mobilizing 200 million people in 141 countries and lifting the status of environmental issues onto the world stage, Earth Day activities in 1990 gave a huge boost to recycling efforts worldwide and helped pave the way for the 1992 United Nations Earth Summit in Rio de Janeiro. Unlike the first Earth Day in 1970, this 20th Anniversary was waged with stronger marketing tools, greater access to television and radio, and multimillion-dollar budgets.

Two separate groups formed to sponsor Earth Day events in 1990: The Earth Day 20 Foundation, assembled by Edward Furia (Project Director of Earth Week in 1970), and Earth Day 1990, assembled by Denis Hayes (National Coordinator for Earth Day 1970). Senator Gaylord Nelson, the original founder of Earth Day, was honorary chairman for both groups. The two did not combine forces over disagreements about leadership of combined organization and incompatible structures and strategies. Among the disagreements, key Earth Day 20 Foundation organizers were critical of Earth Day 1990 for including on their board Hewlett Packard, a company that at the time was the second-biggest emitter of chlorofluorocarbons in Silicon Valley and refused to switch to alternative solvents. In terms of marketing, Earth Day 20 had a grassroots approach to organizing and relied largely on locally based groups like the National Toxics Campaign, a Boston-based coalition of 1,000 local groups concerned with industrial pollution. Earth Day 1990 employed strategies including focus group testing, direct mail fund raising, and email marketing.

The Earth Day 20 Foundation highlighted its April 22 activities in George, Washington, near the Columbia River with a live satellite phone call with members of the historic Earth Day 20 International Peace Climb who called from their base camp on Mount Everest to pledge their support for world peace and attention to environmental issues. The Earth Day 20 International Peace Climb was led by Jim Whittaker, the first American to summit Mt. Everest (many years earlier), and marked the first time in history that mountaineers from the United States, Soviet Union, and China had roped together to climb a mountain, let alone Mt. Everest. The group also collected over two tons of trash (transported down the mountain by support groups along the way) that was left behind on Mount Everest from previous climbing expeditions. The master of ceremonies for the Columbia Gorge event was the TV star, John Ratzenberger, from "Cheers", and the headlining musician was the "Father of Rock and Roll," Chuck Berry.

Warner Bros. Records released a single in 1990 titled "Tomorrow's World", written by Kix Brooks (who would later become one-half of Brooks & Dunn) and Pam Tillis. The song featured vocals from Lynn Anderson, Butch Baker, Shane Barmby, Billy Hill, Suzy Bogguss, Kix Brooks, T. Graham Brown, the Burch Sisters, Holly Dunn, Foster & Lloyd, Vince Gill, William Lee Golden, Highway 101, Shelby Lynne, Johnny Rodriguez, Dan Seals, Les Taylor, Pam Tillis, Mac Wiseman, and Kevin Welch. It charted at number 74 on the Hot Country Songs chart dated May 5, 1990.


Earth Day 2000

Earth Day 2000 combined the ambitious spirit of the first Earth Day with the international grassroots activism of Earth Day 1990. This was the first year that Earth Day used the Internet as its principal organizing tool, and it proved invaluable domestically and internationally. Kelly Evans, a professional political organizer, served as executive director of the 2000 campaign. The event ultimately enlisted more than 5,000 environmental groups outside the United States, reaching hundreds of millions of people in a record 183 countries. Leonardo DiCaprio was the official host for the event, and about 400,000 participants stood in the cold rain during the course of the day.


Subsequent Earth Day events

To turn Earth Day into a sustainable annual event rather than one that occurred every 10 years, Nelson and Bruce Anderson, New Hampshire's lead organizer in 1990, formed Earth Day USA. Building on the momentum created by thousands of community organizers around the world, Earth Day USA coordinated the next five Earth Day celebrations through 1995, including the launch of EarthDay.org. Following the 25th Anniversary in 1995, the coordination baton was handed to Earth Day Network.

As the millennium approached, Hayes agreed to spearhead another campaign, this time focusing on global warming and pushing for clean energy. The April 22 Earth Day in 2000 combined the big-picture feistiness of the first Earth Day with the international grassroots activism of Earth Day 1990. For 2000, Earth Day had the Internet to help link activists around the world. By the time April 22 came around, 5,000 environmental groups around the world were on board, reaching out to hundreds of millions of people in a record 184 countries. Events varied: A talking drum chain traveled from village to village in Gabon, Africa, for example, while hundreds of thousands of people gathered on the National Mall in Washington, D.C., USA.

Earth Day 2007 was one of the largest Earth Days to date, with an estimated billion people participating in the activities in thousands of places like Kiev, Ukraine; Caracas, Venezuela; Tuvalu; Manila, Philippines; Togo; Madrid, Spain; London; and New York.


The Earth Day name

According to Nelson, the moniker "Earth Day" was "an obvious and logical name" suggested by "a number of people" in the fall of 1969, including, he writes, both "a friend of mine who had been in the field of public relations" and "a New York advertising executive," Julian Koenig. Koenig, who had been on Nelson's organizing committee in 1969, has said that the idea came to him by the coincidence of his birthday with the day selected, April 22; "Earth Day" rhyming with "birthday," the connection seemed natural. Other names circulated during preparations—Nelson himself continued to call it the National Environment Teach-In, but national coordinator Denis Hayes used the term Earth Day in his communications and press coverage of the event was "practically unanimous" in its use of "Earth Day," so the name stuck.


Earth Day Network

The Earth Day Network was founded in 1993 by Earth Day New York, San Diego Earth Day, Earth Day Chicago, Earth Day Los Angeles, Earth Day St. Louis and Earth Day Canada with a goal of creating an international network dedicated to supporting grassroots Earth Day organizing. Earth Day New York and San Diego Earth Day kept the fledgling entity going for a number of years but ultimately invited Denis Hayes to become chairman of the organization in time for Earth Day 2000. Under Denis’ leadership the Network organized the world-wide events for the 30th Anniversary and has grown into an established Washington, DC-based organization that promotes environmental activism and year-round progressive action, domestically and internationally. Earth Day Network members include NGOs, quasi-governmental agencies, local governments, activists, and others. Earth Day Network members focus on environmental education; local, national, and global policies; public environmental campaigns; and organizing national and local earth day events to promote activism and environmental protection. The international network reaches over 25,000 organizations in 192 countries, while the domestic program engages 10,000 groups and over 100,000 educators coordinating millions of community development and environmental-protection activities throughout the year.

In observance of the 40th anniversary of the April 22 Earth Day, Earth Day Network created multiple global initiatives, ranging from a Global Day of Conversation with mayors worldwide, focusing on bringing green investment and building a green economy; Athletes for the Earth Campaign that brings Olympic, professional, and every day athletes' voices to help promote a solution to climate change; a Billion Acts of Green Campaign which will aggregate the millions of environmental service commitments that individuals and organizations around the world make each year; to Artist for the Earth, a campaign the involves hundreds of arts institutions and artists worldwide to create environmental awareness. EDN mobilized 1.5 billion people in 190 countries to participate in these global events and programs, and helped create Earth Day organizations worldwide.


History of the Equinox Earth Day (March 20)

The equinoctial Earth Day is celebrated on the March equinox (around March 20) to mark the precise moment of astronomical mid-spring in the Northern Hemisphere, and of astronomical mid-autumn in the Southern Hemisphere. An equinox in astronomy is that moment in time (not a whole day) when the center of the Sun can be observed to be directly "above" the Earth's equator, occurring around March 20 and September 23 each year. In most cultures, the equinoxes and solstices are considered to start or separate the seasons.

John McConnell first introduced the idea of a global holiday called "Earth Day" at the 1969 UNESCO Conference on the Environment. The first Earth Day proclamation was issued by San Francisco Mayor Joseph Alioto on March 21, 1970. Celebrations were held in various cities, such as San Francisco and in Davis, California with a multi-day street party. UN Secretary-General U Thant supported McConnell's global initiative to celebrate this annual event; and on February 26, 1971, he signed a proclamation to that effect, saying:

May there be only peaceful and cheerful Earth Days to come for our beautiful Spaceship Earth as it continues to spin and circle in frigid space with its warm and fragile cargo of animate life.

United Nations secretary-general Kurt Waldheim observed Earth Day with similar ceremonies on the March equinox in 1972, and the United Nations Earth Day ceremony has continued each year since on the day of the March equinox (the United Nations also works with organizers of the April 22 global event). Margaret Mead added her support for the equinox Earth Day, and in 1978 declared:

"Earth Day is the first holy day which transcends all national borders, yet preserves all geographical integrities, spans mountains and oceans and time belts, and yet brings people all over the world into one resonating accord, is devoted to the preservation of the harmony in nature and yet draws upon the triumphs of technology, the measurement of time, and instantaneous communication through space.
Earth Day draws on astronomical phenomena in a new way – which is also the most ancient way – by using the vernal Equinox, the time when the Sun crosses the equator making the length of night and day equal in all parts of the Earth. To this point in the annual calendar, EARTH DAY attaches no local or divisive set of symbols, no statement of the truth or superiority of one way of life over another. But the selection of the March Equinox makes planetary observance of a shared event possible, and a flag which shows the Earth, as seen from space, appropriate."

At the moment of the equinox, it is traditional to observe Earth Day by ringing the Japanese Peace Bell, which was donated by Japan to the United Nations. Over the years, celebrations have occurred in various places worldwide at the same time as the UN celebration. On March 20, 2008, in addition to the ceremony at the United Nations, ceremonies were held in New Zealand, and bells were sounded in California, Vienna, Paris, Lithuania, Tokyo, and many other locations. The equinox Earth Day at the UN is organized by the Earth Society Foundation.

Earth Day ringing the peace bell is celebrated around the world in many towns, ringing the Peace Bell in Vienna, Berlin, and elsewhere. A memorable event took place at the UN in Geneva, celebrating a Minute for Peace ringing the Japanese Shinagawa Peace Bell with the help of the Geneva Friendship Association and the Global Youth Foundation. directly after in deep mourning about the Fukushima Daiichi Nuclear Power Plant catastrophe 10 days before.

Beside the Spring Equinox for the Northern Hemisphere, the observance of the Spring Equinox for the Southern Hemisphere is of equal importance ! It is a "new sign of hope" for Peace that the International Day of Peace http://www.un.org/en/events/peaceday/ is celebrated on the Spring Equinox of the South! right along the original intentions of John McDonnell, U-Thant, Muller, Mead,...


Growing eco-activism before Earth Day 1970

In 1968, Morton Hilbert and the U.S. Public Health Service organized the Human Ecology Symposium, an environmental conference for students to hear from scientists about the effects of environmental degradation on human health. This was the beginning of Earth Day. For the next two years, Hilbert and students worked to plan the first Earth Day. In April 1970—along with a federal proclamation from U.S. Sen. Gaylord Nelson—the first Earth Day was held.

Project Survival, an early environmentalism-awareness education event, was held at Northwestern University on January 23, 1970. This was the first of several events held at university campuses across the United States in the lead-up to the first Earth Day. Also, Ralph Nader began talking about the importance of ecology in 1970.

The 1960s had been a very dynamic period for ecology in the US. Pre-1960 grassroots activism against DDT in Nassau County, New York, had inspired Rachel Carson to write her bestseller, Silent Spring (1962).


Significance of April 22

Nelson chose the date in order to maximize participation on college campuses for what he conceived as an "environmental teach-in". He determined the week of April 19–25 was the best bet as it did not fall during exams or spring breaks. Moreover, it did not conflict with religious holidays such as Easter or Passover, and was late enough in spring to have decent weather. More students were likely to be in class, and there would be less competition with other mid-week events—so he chose Wednesday, April 22.

Unbeknownst to Nelson, April 22, 1970, was coincidentally the 100th anniversary of the birth of Vladimir Lenin. Time reported that some suspected the date was not a coincidence, but a clue that the event was "a Communist trick", and quoted a member of the Daughters of the American Revolution as saying, "subversive elements plan to make American children live in an environment that is good for them." J. Edgar Hoover, director of the U.S. Federal Bureau of Investigation, may have found the Lenin connection intriguing; it was alleged the FBI conducted surveillance at the 1970 demonstrations. The idea that the date was chosen to celebrate Lenin's centenary still persists in some quarters, an idea borne out by the similarity with the subbotnik instituted by Lenin in 1920 as days on which people would have to do community service, which typically consisted in removing rubbish from public property and collecting recyclable material. Subbotniks were also imposed on other countries within the compass of Soviet power, including Eastern Europe, and at the height of its power the Soviet Union established a nation-wide subbotnik to be celebrated on Lenin's birthday, April 22, which had been proclaimed a national holiday celebrating communism by Nikita Khrushchev in 1955.

In Nebraska, Arbor Day falls on April 22, that being the birthday of Julius Sterling Morton, the founder of the national tree-planting holiday that started in 1872, which has been a legal holiday in the state since 1885. According to the National Arbor Day Foundation "the most common day for the state observances is the last Friday in April ... but a number of state Arbor Days are at other times in order to coincide with the best tree-planting weather." It has since been largely eclipsed by the more widely observed Earth Day.


Earth Day ecology flag

According to Flags of the World, the Ecology Flag was created by cartoonist Ron Cobb, published on November 7, 1969, in the Los Angeles Free Press, and then placed in the public domain. The symbol, resembling the Greek letter theta, is a combination of the letters "E" and "O" taken from the words "Environment" and "Organism," respectively. The flag is patterned after that of the United States, with thirteen alternating-green-and-whites stripes. Its canton is green with a yellow theta. Later flags used either the ecology symbol or the peace symbol.

Earth Day Canada

The first Canadian Earth Day was held on Thursday, September 11, 1980, and was organized by Paul D. Tinari, then a graduate student in Engineering Physics/Solar Engineering at Queen's University. Flora MacDonald, then MP for Kingston and the Islands and Canadian Secretary of State for External Affairs, officially opened Earth Day Week on September 6, 1980 with a ceremonial tree planting and encouraged MPs and MPPs across the country to declare a cross-Canada annual Earth Day. The principal activities taking place on the first Earth Day included educational lectures given by experts in various environmental fields, garbage and litter pick-up by students along city roads and highways as well as tree plantings to replace the trees killed by Dutch Elm Disease.

Earth Day Canada (EDC) is a national environmental charity founded in 1990 that provides Canadians with practical knowledge, tools, and simple easy-to-accomplish actions to support a healthier environment through EDC's year-round and award-winning programs.

Education: EcoKids supports teachers and students, grades K-8, with free educational resources, curriculum-linked lesson plans including ESL and FSL, and homework help and games for students. EcoMentors offers youth the training and resources they need to facilitate local environmental education workshops with their peers and other young Canadians.

Action: EDC's challenges, contests and campaigns promote practical, culturally relevant and cost-effective solutions to help individual Canadians support a healthier environment. EDC also encourages action by supporting individuals and community groups in the organization and delivery of local Earth Day (April 22) events.

Recognition and Financial Support: Toyota Earth Day Scholarship Program recognizes tomorrow's environmental leaders providing twenty $5 000 scholarships to graduating high school students going on to post-secondary education in the discipline of their choice. The Hometown Heroes Award Program recognizes environmental leaders at the community level with an individual and a group award (each with a cash-prize of $10 000), and business leaders with a small business award. Earth Day Canada's Community Environment Fund funds sustainable community projects in Ontario providing grants of up to $20 000 to schools and not-for-profit organizations.

The Diversity Engagement and Inclusion Initiative helps the environmental sector to better communicate with, engage and activate Canada's diverse social and cultural communities. The Employee Engagement program works with employers to achieve business and sustainability goals through inclusion of best practices.
