2023 Earth Day Theme

Our planet is an amazing place, but it needs our help to thrive. That's why, this year on April 22, with the theme 'Invest in Our Planet', more than a billion people celebrate Earth Day to protect the planet from things like pollution and deforestation. By taking part in activities like picking up litter and planting trees, we're making the world a happier, healthier place to live. 

The Origin of Earth Day and What it Means Today

Earth Day was first celebrated in 1970 in the United States, inspired by the devastating oil spill in Santa Barbara, California, in 1969. That year, at a UNESCO conference in San Francisco, peace activist John McConnell proposed a day to honor the Earth and the concept of peace, to first be observed on March 21, 1970 - the first day of spring in the northern hemisphere. This day of nature's equipoise was later sanctioned in a proclamation written by McConnell and signed by Secretary-General U Thant at the United Nations.


Save the Earth - Earth Day Theme


A month later, United States Senator Gaylord Nelson proposed the idea to hold a nationwide environmental teach-in on April 22, 1970. He hired a young activist, Denis Hayes, to be the National Coordinator. Nelson and Hayed renamed the event 'Earth Day'. Denis and his staff grew the event beyond the original idea for a teach-in to include the entire United States. More than 20 million people poured out on the streets, and the first Earth Day remains the largest single-day protest in human history. It also helped spur the creation of the Environmental Protection Agency and the passage of important environmental legislation.

How it Spread Across the Rest of the World 

As 1990 approached, a group of environmental leaders approached Denis Hayes to once again organize another major campaign for the planet. This time, Earth Day went global, mobilizing 200 million people in 141 countries and lifting environmental issues onto the world stage. Earth Day 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. It also prompted President Bill Clinton to award Senator Nelson the Presidential Medal of Freedom — the highest honor given to civilians in the United States — for his role as Earth Day founder.

On Earth Day 2016, the landmark Paris Agreement was signed by the United States, the United Kingdom, China, and 120 other countries. This signing satisfied a key requirement for the entry into force of the historic draft climate protection treaty adopted by the consensus of the 195 nations present at the 2015 United Nations Climate Change Conference in Paris. 

Earth Day Today

In the decades since its inception, Earth Day has become a truly global event, celebrated in more than 190 countries around the world. It is a day for people of all backgrounds to come together and take action to protect the planet. Earth Day events take many different forms, from educational programs and community clean-up projects to political activism and public demonstrations. One of the key reasons for Earth Day's global success is its ability to unite people across borders and cultures for a common cause. Environmental issues affect everyone, regardless of where they live or what their background is. By working together on Earth Day and throughout the year, people around the world can help create a sustainable future for our planet and all its inhabitants, including the beautiful plants and flowers that we love.

How People Celebrate Earth Day

Planting Trees

Planting trees is a popular way to celebrate Earth Day. Trees absorb carbon dioxide, provide habitat for wildlife, and help combat climate change. Planting trees is also a fun way to get outside and connect with nature.

Cleaning Up Litter

Cleaning up litter is another way to celebrate Earth Day. Picking up trash in your community can help prevent it from entering our oceans and waterways, where it can harm wildlife and ecosystems.

Reducing Waste

Reducing waste is an important way to protect the planet. Earth Day is a good time to start reducing your waste by using reusable bags, water bottles, and containers. You can also start composting to reduce the amount of food waste that goes into landfills.
