Earth Day 2025
When is Earth Day in 2025?
Earth Day is celebrated annually on April 22. In some countries, it's also celebrated on the March Equinox. However, you don't need to limit yourself to one day; you can organize Earth Month and dedicate more time to environmental actions.
What is the Earth Day 2025 theme?
According to the official Earth Day website, the theme of Earth Day 2025 is “OUR POWER, OUR PLANET.” The focus this year is on renewable energy, with a global goal to triple the production of clean electricity by 2030.
Earth Action Day: how to get involved?
This year’s Earth Day also carries the subtitle Earth Action Day, highlighting the idea that meaningful change starts with each of us. The Earth Day organizers highlight four ways to get involved:
-
Educating: Learning the facts about climate change and clean energy, and sharing them with your community.
-
Advocating: Using your voice to push for change. Signing petitions, contacting your local leaders, and demanding action on renewable energy and environmental protection.
-
Mobilizing: Organizing or joining local events like rallies, town halls, or campus teach-ins to bring people together and raise awareness.
-
Pledging: Sharing your commitment on social media. Using your platform to inspire others to get involved in Earth Day.
You can also join the celebration of Earth Day by trying our engaging quiz! It's fun and informative for kids and adults alike, helping everyone learn more about our planet in an interactive way.
Earth Month 2025
Extending Earth Day, the entire month of April is celebrated as Earth Month – a time to build lasting habits that help keep the planet clean and green. Here are some ideas you can practice throughout April (and beyond!):
- Pick up trash while you’re walking;
- Turn off lights when not in use;
- Limit your water usage;
- Plant a tree or donate to a reforestation project;
- Switch to e-books;
- Choose plant-based meals;
- Use a reusable water bottle;
- Buy glass or paper products;
- Use environmentally friendly cleaning products;
- Switch to reusable bags;
- Volunteer on ecological projects.
History of Earth Day
The first Earth Day was held in 1970 in the US by Senator Gaylord Nelson. It turned into a nationwide demonstration for environmental awareness. Later that year, the Environmental Protection Agency was created too. The movement has grown rapidly, and nowadays, as the official Earth Day Network declares, about 1 billion people participate in Earth Day annually.
Likewise, in 1972, the United Nations conducted the Conference on the Human Environment in Stockholm. That started an age of global awareness. Coincidentally or not, the General Assembly designated April 22 as International Mother Earth Day in 2009. Mother Earth Day implies that various nations commonly call the Earth their “mother,” and we all must care about our common home and be grateful to it. Both events now are aimed to confront climate change and inspire people to be environmentally friendly.
Earth Day from a space perspective
Every day is Earth Day if you look at it from space. It becomes clear that humans are an infinitesimal part of the Universe, and our Earth is a fragile spaceship that we must protect. After all, seeing the Earth from above helps to better understand its issues.
Space science contributes a lot to preventing and solving climate change. For example, the Landsat missions flown by NASA in cooperation with the United States Geological Survey examine the condition of the Earth’s forests. The data they collect on the Amazon rainforest helps to explore the causes and effects of a fire season and send deforestation alerts. Another NASA mission, the Suomi National Polar-orbiting Partnership mission (Suomi NPP), also tracks thermal anomalies. Moreover, it monitors changes to global ice cover, the health of the ozone layer, air pollution, and other Earth conditions.
The European Union’s Copernicus Sentinels launched by the European Space Agency also collect data on the Earth’s health. They measure the behavior of the oceans, lands, and atmosphere and give an emergency management overview to predict earthquakes and tornadoes. Even dense marine plastic accumulations can be detected from above – as proved by Copernicus Sentinel-2, whose data is now used for that purpose. And these are indeed not the only examples of how space science helps us protect the Earth.
Green technologies developed for space missions also serve for everyday life, like reusable water bottles with built-in filters or flexible solar panels. Dozens of satellites in orbit along with astronauts on the International Space Station, study the Earth from above, while scientists analyze the records and propose solutions. However, even the provided scientific data wouldn’t help without public engagement.
Celebrate Earth's birthday by stargazing
In 2025, Earth Day on April 22 comes with a cosmic treat — the Lyrid meteor shower peaks that same night! This could be another opportunity to honor Earth's “birthday.”
Take a break from city lights, join an eco-event or cleanup outside the city, and stay to enjoy the night sky. You may see up to 18 meteors per hour during the peak. The Lyrids are best seen from the Northern Hemisphere, but southern regions may also see a few shooting stars. To find the best time to watch the meteor shower from your location, check the Meteors tab in the calendar of the Sky Tonight app. You can also check out our meteor shower infographic to discover other upcoming events and get tips for observations.
Stargazing helps us see Earth's place in the Universe — and connect with nature on this special day from a different perspective.
What is Earth Day: Conclusion
Earth Day’s mission is to remind us that nature and humankind are inseparably connected. “When we see the Earth from space, we see ourselves as a whole… one planet, one human race” – such an Earth Day message was delivered by ESA and The Stephen Hawking Foundation on April 22, 2020. All of us across the globe are connected by our Mother Planet Earth. And we all can make an effort to make it a better place to live. So, let’s do it!
