Earth Day is an annual event celebrated on April 22nd worldwide. Every year, the Earth Day theme is announced. Earth Day is a day of action and a reminder for everyone to reflect on the impact of human activity on the planet. It is also a day to celebrate our beautiful planet and take action to preserve it.
The Earth Day Theme 2023 is 'Invest in Our Planet'
This year's Earth Day theme is designed to persuade businesses, governments, and citizens around the world of the need to invest in our planet to improve our environment and give our descendants a better and safer future.
“In 2023 we must come together again in partnership for the planet. Businesses, governments, and civil society are equally responsible for taking action against the climate crisis and lighting the spark to accelerate change toward a green, prosperous, and equitable future. We must join together in our fight for the green revolution, and for the health of future generations. The time is now to Invest In Our Planet,”
said Kathleen Rogers, President of earthday.org.
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.
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.
