Importance of World Environment Day for Students and Why We Celebrate: A complete guide

Every year, people across the world come together on 5 June to observe World Environment Day. For students especially, this day holds great value. It serves as a reminder that looking after the planet is not just the job of governments or big companies — it’s something each of us can do, every single day. 

As a result, understanding the importance of World Environment Day early in life helps young people grow into responsible citizens who care for nature and make thoughtful choices.

When is Environment Day and Why Do We Celebrate It?

World Environment Day is celebrated on 5 June every year.

So, why do we celebrate it? The day aims to make people more aware of the problems facing the planet — such as plastic waste, water pollution, deforestation, and climate change. It encourages action at every level — schools, families, local groups, businesses, and individuals. For students, it’s a chance to learn more about the world around them, and to take part in projects and events that make a difference.

Some of the best schools in Ahmedabad actively include such activities in their yearly calendars to help students develop a deep respect for nature.

World Environment Day History

The idea for World Environment Day began in 1972 when the United Nations hosted the Conference on the Human Environment in Stockholm, Sweden. This meeting led to the creation of the United Nations Environment Programme (UNEP), which is now responsible for organising this global event. 

The first celebration took place in 1973, and since then, it has grown into one of the largest worldwide platforms for environmental awareness. Each year, the event is hosted by a different country and focuses on a different issue. Over 150 countries now take part, showing how much it has grown in impact.

Also, there is a celebration theme each year that focuses on major environmental issues. So, let’s see what was the theme of 2025.

Theme of World Environment Day 2025

The theme of World Environment Day 2025 was “Beat Plastic Pollution”, celebrated in Jeju, South Korea. The focus was on reducing plastic waste, which continues to harm animals, pollute waterways, and damage the environment. To address this, students are encouraged to take simple but meaningful steps — like refusing single-use plastics, choosing reusable items, and learning proper recycling habits.

Many of the best primary schools use this theme to guide eco-friendly classroom activities and events. This helps students comprehend the real-world impact of their choices and encourages action at a young age.

Let’s see how GIIS encourages students in everyday life to care for our environment.

GIIS Ahmedabad’s Green Initiative

Global Indian International School (GIIS), Ahmedabad supported environmental awareness through a Plantation Drive, encouraging students to take part in sustainable action.

Over 3000 saplings were distributed, led by Vice Principal Ms Ronak Purohit, with a strong message from Principal Mr Caesar D’silva:

“Each tree planted today is a promise of a better tomorrow.”

Students proudly shared their planting efforts, feeling inspired to protect nature. The school’s hands-on approach made the event both meaningful and memorable.
