What is Earth Day? When is Earth Day 2025?

Earth Day is an annual event held on April 22 to raise awareness and inspire action toward environmental protection. It’s a time for individuals and communities to reflect on how we treat the planet and to spread habits that promote sustainable and green living.

In 2025, Earth Day will fall on Tuesday, April 22. Around this time, many countries—including Vietnam—organize community events such as litter cleanups, tree planting, or even simple actions like turning off lights to show support for the Earth.

The Origins of Earth Day

Earth Day was born in the late 1960s—a time when the environment in the United States was suffering heavily due to rapid industrialization, yet environmental awareness remained low.

Following a massive oil spill in California in 1969, U.S. Senator Gaylord Nelson proposed April 22, 1970, as a national day of environmental activism. He partnered with Denis Hayes, a dynamic young student, to mobilize universities, colleges, communities, and governments.

Senator Gaylord Nelson is considered the “father” of Earth Day

As a result, more than 20 million Americans—from students to workers—took to the streets, participating in marches, discussions, and seminars on pollution, biodiversity, and sustainable development. It became the first large-scale environmental event in the world and led to major milestones such as the creation of the U.S. Environmental Protection Agency (EPA) and landmark environmental laws.

By 1990, Earth Day had become a global movement, with over 200 million participants across 141 countries.

The Modern Relevance of Earth Day

As we face global issues like climate change, resource depletion, and plastic pollution, Earth Day serves as a powerful reminder of each individual's responsibility toward the planet. Far from being merely symbolic, it encourages real, long-term action—from personal lifestyle changes to policy-level initiatives.

Simple acts like reducing plastic use, joining environmental clubs, or running awareness campaigns are all meaningful ways to participate.

Earth Day is not just about “one day of action”—it points to a lifestyle rooted in harmony with nature and long-term responsibility for the future of ourselves and the next generation.

Conclusion

Earth Day isn’t only for environmental activists. It’s for all of us—everyone who lives, studies, and works on this planet. The Earth doesn’t need perfect actions, but millions of imperfect efforts done consistently. And who knows? A big change might start with your small concern today.
