Earth Day is celebrated every April 22nd with the main objective of raising awareness about the importance of caring for our planet and preserving it for future generations. This initiative aims to remind us of fundamental environmental values and promote sustainability, biodiversity protection, and the fight against climate change. Below, we tell you everything you need to know about this important day, its history, how it is celebrated, and what you can do to contribute.
When Earth Day began to be celebrated
The first Earth Day was celebrated on April 22, 1970. This day marked the beginning of a massive environmental movement in the United States, when more than 20 million Americans demonstrated in defense of the environment. The initiative was spearheaded by U.S. Senator Gaylord Nelson , who sought to draw attention to the environmental problems caused by industrialization and pollution.
Thanks to this mobilization, a historic milestone was achieved: the creation of the United States Environmental Protection Agency (EPA) , as well as the enactment of key laws for the protection of air and water. This effort not only marked a turning point in environmental legislation in the United States, but also inspired other countries to adopt similar measures. Since then, Earth Day has become a global celebration, extending to more than 190 countries and bringing together more than one billion people each year. In 2009, the United Nations officially recognized this date as International Mother Earth Day , highlighting its global importance.
How Earth Day is celebrated
Earth Day is commemorated in many ways, highlighting the importance of protecting the environment. Common activities include:
- Public demonstrations and marches:In cities around the world, people are gathering to demonstrate in favor of responsible environmental policies.
- Plant trees: This activity is one of the most popular, since trees contribute to mitigating climate change by absorbing carbon dioxide.
- Community cleanings: Many organizations and communities participate in beach, forest and urban area clean-ups.
- Educational projects: Activities are organized in schools and universities to raise awareness among students about environmental challenges and how they can contribute.
The official 2023 motto, " Invest in our planet ", seeks to highlight the need for collaboration between governments, businesses and citizens to create a green economy that benefits both the environment and society.
It is important to remember that, although these activities are essential, the real key is to incorporate sustainable practices into our daily lives, such as reducing plastic consumption, promoting the use of renewable energy and becoming aware of our impact on the planet.
Repercussions at a global level

Over the years, Earth Day has had a significant global impact. Currently, more than one billion people in 190 countries participate in activities related to this day. Major cities like San Francisco, Moscow, Brussels , and Marrakech organize large-scale events where citizens plant trees, clean parks, and contact their political representatives to demand more sustainable policies.
Despite the efforts made, the planet continues to face serious threats such as climate change, biodiversity loss , and the pollution of natural resources. It is clear that a single day is not enough to address these challenges. However, Earth Day serves an essential purpose: reminding us that we must take continuous action to protect our environment and ensure a more sustainable future.
The origin of the name: Mother Earth Day
The term Earth Day was adopted by the UN in 2009 to underscore the importance of the Earth not only as a physical planet, but as a living being that provides us with resources and sustains all life. It seeks to promote a fair balance between economic, social, and environmental needs to ensure the well-being of present and future generations.
Furthermore, this day aims to raise awareness about critical issues such as overpopulation , deforestation , and pollution . Countries commit through international treaties to reduce their greenhouse gas emissions and promote the use of renewable energy as part of their strategies to combat climate change.
How you can contribute on Earth Day
If you care about the environment and want to contribute, here are some simple but effective actions you can take:
- Switch to energy-saving or LED light bulbs: They significantly reduce electricity consumption.
- Get informed and share: Explain to your friends and family the benefits of renewable energy and the risks associated with the use of fossil fuels.
