GET INVOLVED

How to Celebrate World Environment Day

Reduce your carbon footprint

Take stock of your daily life and try to identify areas where you can reduce your carbon footprint. This could include reducing your electricity use, using public transportation, walking or biking more often, and reusing products.

PLANT

Plant a tree

Trees are essential for cleaning the air and providing habitat for wildlife. Planting a tree is a great way to celebrate World Environment Day and help the environment.

PICK

Pick up litter

Take some time to pick up trash in your neighborhood. Trash can be toxic to wildlife and have a negative impact on the environment. Picking it up helps prevent this pollution.

EAT

Eat locally sourced food

Buy food that is produced locally instead of food that traveled long distances to get to your plate. Eating local food reduces your carbon footprint and supports local farmers.

EDUCATE

Educate others

Spread the word about environmental issues by talking to family and friends about World Environment Day and why it is important to protect our planet.

WHY THIS DAY MATTERS

Why World Environment Day is Important

Promoting sustainable habits

World Environment Day serves as a reminder that individuals have an important role to play when it comes to protecting our planet. Celebrating this day is a great way to set aside time for reflecting on our current habits and thinking about ways we can make more sustainable decisions - both in what we consume and how we dispose of materials.

Raising awareness of environmental issues

World Environment Day is a great opportunity to raise awareness about the current state of the environment and the dangers that our planet is facing. It's also a chance to encourage people to make sustainable choices in their everyday lives, whether it be reducing their plastic waste, conserving energy or choosing materials with less of an environmental impact.

Creating global conversations about climate change

World Environment Day is one of the few days each year where the entire world has the opportunity to join together and talk about solutions for tackling climate change. From politicians to businesses to everyday citizens, World Environment Day serves as an important platform for sparking global conversations about how we can all work together towards creating a healthier future planet.
