Earth Day is a worldwide event that occurs annually on April, 22. It celebrates the environmental diversity of Earth and highlights ways of protecting our planet.

When we hear terms like "code red for humanity" and "climate change", it can feel difficult to focus on the small actions individuals and communities can take to address the climate crisis. But Earth Day strives to highlight how everyone can be part of the change.

Read on to learn more about Earth Day, its importance and how we can make a difference through small actions or community involvement.

Earth Day is an annual event that started in 1970 when 20 million Americans — 10% of the population of the U.S. at the time — came together to demonstrate the importance of increasing protection for our planet, according to the official Earth Day website EARTHDAY.ORG.

Nowadays it works with more than 150,000 partners in over 192 countries with 1 billion individuals involved, according to the official Earth Day website. Earth Day celebrates our planet and highlights the need to hold sectors accountable for their role in the environmental crisis.

"Everyone accounted for, and everyone accountable" EARTHDAY.ORG states.

Environmental problems have become so urgent and widespread, that scientists and environmental organizations alike are saying addressing climate change is more urgent than ever. Jane Goodall, a chimpanzee researcher for the past 60 years, is among those scientists calling for a whole-systems approach to examining how to protect our climate.

"None of us can do it alone. It's quite ridiculous. The problems are huge," Goodall said at the 2021 Nature Conservancy in California Summit, available on YouTube.

"We need every single organization that cares about the future of the planet to get together and to work out ways that we can share these small pools of money available, and find ways of lobbying those billionaires who have so much money to help us so that we don't have to fight and squabble over funding," Goodall added.

Earth Day theme 2024

Each Earth Day has a specific theme, this year it's "Planets vs. Plastics", according to the official website.

More plastic has been produced in the last ten years than in the entire 20th century according to EARTHDAY.ORG.

"EARTHDAY.ORG is unwavering in our commitment to end plastics for the sake of human and planetary health, demanding a 60% reduction in the production of ALL plastics by 2040," their mission statement reads.

Planets vs. Plastics aims to unite students, parents, businesses, governments, churches, unions, individuals and NGOs to end the use of plastics for the sake of human and planetary health.

"The Planet vs. Plastics campaign is a call to arms, a demand that we act now to end the scourge of plastics and safeguard the health of every living being upon our planet," said Kathleen Rogers, EARTHDAY.ORG president in a mission statement.

More than 500 billion plastic bags, that's one million bags per minute, were produced worldwide last year. 100 billion plastic beverage containers were sold last year in the United States alone, more than 300 bottles per inhabitant.

A stark statistic is that 95% of all plastics in the U.S. won't be recycled. The recycled 5% is either "downcycled" to inferior products or shipped abroad for "recycling", all of this leaves the demand for virgin plastic undiminished according to EARTHDAY.ORG.

How you can take part in Earth Day

Earth Day events take place in many countries around the world. Consult the official map to see what is taking place close to you.

The official Earth Day website has a list of 52 activities that you can do in small groups or from home if you prefer to participate that way. For example, you can use your computer instead of a printer, to view materials. The website also suggests actions as small as picking up trash while you run, to as large as organizing community cleanup or contacting your local political representative for climate change or environmental pollution prevention strategies.

You can also sign up to volunteer with EARTHDAY.ORG, become an Earth Day member and even register your own Earth Day event for people to take part in.

Agencies like NASA have a helpful Earth Day toolkit which includes great resources and Earth Day activities for you to enjoy in the community or at home. The Old Farmer's Almanac also has 10 mini-activities that you can do such as planting flowers to attract pollinating creatures like bees, stopping pesticide use in your garden, and managing your water consumption carefully.

When and why was Earth Day established?

The U.S. Environmental Protection Agency notes that 1970 was a very different world for all of us. Not only was there no Clean Air Act, Clean Water Act, nor even an EPA, but overall, "there were no legal or regulatory mechanisms to protect our environment," the agency states.

Americans and others, however, were already aware of the toll on the environment that chemicals were taking. Events such as the publication of Rachel Carson's book "Silent Spring" (1962) which showed the environmental effect of chemicals, and a 1969 oil slick fire on Cleveland's Cuyahoga River, both caught a lot of public attention, according to History.com.

That began to change in 1969, when Senator Gaylord Nelson (D.-Wis.) borrowed from the idea of anti-Vietnam War "teach-ins", or discussions, on campuses across the United States, History.com added. Nelson, an environmentalist, wanted to adopt the same type of grassroots approach to protecting the environment. It was Nelson who first announced the concept of an Earth Day in the fall of 1969, and following massive public support, the first Earth Day was celebrated on April 22, 1970.

My primary objective in planning Earth Day was to show the political leadership of the nation that there was broad and deep support for the environmental movement," Nelson, who died in 2005, said in 1980.

"While I was confident that a nationwide peaceful demonstration of concern would be impressive, I was not quite prepared for the overwhelming response that occurred on that day," Nelson continued.

"Two thousand colleges and universities, 10,000 high schools and grade schools, and ... more than 20 million Americans participated in one of the most exciting and significant grassroots efforts in the history of this country."
