World Environment Day 2025: World Environment Day is celebrated on June 5 every year, with the aim of being a global marketing day for environmental outreach and action. Activities are organised in more than 150 countries; this day is an emergency call to save the Earth. Awareness programmes, plantation drives, clean-up campaigns, and sustainable events are organised in offices, schools, government departments, and local organisations to focus attention on urgent environmental issues.

Theme Of World Environment Day 2025:

The theme of this year is 'Putting an end to plastic pollution' in 2025. It supports the global campaign led by UNEP, #BeatPlasticPollution, whereby everyone is encouraged to go green and look out for sustainable alternatives. With growing concern over the devastating effects of plastic pollution on the ecosystems, this World Environment Day stresses the need to unite and fight to protect nature for the coming generations.

History Of World Environment Day:

World Environment Day was initially established in 1972 at the United Nations Conference on the Human Environment in Stockholm. In the same year, the UN General Assembly formally declared June 5 to be World Environment Day, which became the primary date for worldwide environmental awareness campaigns. The inaugural celebration was held in 1973 under the slogan "Only One Earth", a strong message of the uniqueness of the planet and the duty of human beings to protect it.

Since its inception, the day has developed into the biggest global event dedicated to environmental concerns. Every year, a host nation is chosen to coordinate the world events, raising awareness about a particular issue. This year, the host nation is the Republic of Korea, with most of the activities taking place in Jeju Province, an area that has gained popularity for its greenery and sustainable strategies. 

Significance Of This Day:

World Environment Day is important in bringing environmental threats to the limelight and spurring transformation. The 2025 theme touches on the plastic crisis in the world, which significantly contributes to pollution, loss of biodiversity, and global warming. At present, 11 million tonnes of plastic flow into water bodies every year, with microplastics polluting soil through landfills and sewage treatment.

The day inspires governments to make significant policy reforms and challenges citizens to take responsibility. Over 150 nations today mark the day through consciousness campaigns, school outreach programmes, public commitments, and cleanups.
