World Environment Day 2025 Sample Speech

Good morning everyone,

Today, we are here to observe World Environment Day, which is celebrated every year on 5 June. This day reminds us of the need to take care of the world we live in. The theme for 2025 is ‘Ending Plastic Pollution’, a topic that affects us all.

Plastic pollution is one of the biggest environmental problems today. Plastic items take hundreds of years to break down. They harm animals, pollute our oceans, and even enter our food and water. It is time for all of us to act.

We can start by saying no to single-use plastics, carrying our own bags, and encouraging others to do the same. Governments and industries also need to find better, eco-friendly solutions.

As students, we have a big role to play. By spreading awareness and making small changes in our daily lives, we can help protect our planet for future generations.

Let us all promise to do our part and make our world cleaner and healthier.

Thank you.

World Environment Day: Working Together to End Plastic Pollution

World Environment Day is observed every year on 5 June to raise awareness about environmental issues. It was first celebrated in 1973 and has become a global event. Each year, the United Nations announces a theme to focus on a specific problem. The theme for 2025 is ‘Ending Plastic Pollution’.

Plastic pollution is a serious problem. Plastics do not break down easily. They collect in rivers, oceans, and on land. Sea animals often eat plastic by mistake and many die because of it. Even people are at risk, as microplastics have been found in food and water.

To stop this, we must change how we use plastic. Replacing plastic with cloth bags, metal bottles, and glass containers is a good start. Recycling and proper waste disposal can also reduce the problem. Schools, governments, and companies must work together to spread awareness and find better solutions.

World Environment Day encourages everyone to act. Students can take part in activities like tree planting, clean-up drives, and recycling programmes. They can also teach others about the dangers of plastic.

This day is a reminder that protecting nature is a shared responsibility. By taking small steps, we can make a big difference and help keep our planet safe and healthy.
