Observed annually on June 5, World Environment Day is the largest international platform dedicated to raising environmental awareness and driving action. With participation from over 150 countries, it rallies governments, communities, and individuals to protect and preserve the planet.

2025 Theme: Ending Plastic Pollution

The 2025 theme is “Putting an End to Plastic Pollution.” This year’s focus aligns with the UN Environment Programme’s #BeatPlasticPollution campaign, which urges communities worldwide to take collective action against the growing plastic waste crisis.

Origins of World Environment Day

World Environment Day was established in 1972 during the United Nations Conference on the Human Environment held in Stockholm, Sweden. The same year, the UN General Assembly officially marked June 5 as World Environment Day. The first celebration in 1973 carried the theme “Only One Earth.” Since then, it has grown into the most significant global awareness campaign for environmental protection.

Why World Environment Day Matters

Plastic pollution is a critical environmental issue contributing to climate change, ecosystem damage, and biodiversity loss. Globally, around 11 million tons of plastic waste enter aquatic systems every year. Microplastics pollute soils and waters, costing the global economy an estimated $300 to $600 billion annually.

World Environment Day isn’t just symbolic. It encourages:

• Government-level policy reforms

• Public education on environmental issues

• Cleanup drives, tree plantation, and awareness campaigns

• Community-driven eco-conscious actions

India’s Plastic Problem: Urgent Attention Needed

India is responsible for nearly 20% of the world’s plastic waste, generating 9.3 to 9.5 million tonnes annually—around 0.12 kg per person per day. Key environmental impacts include:

• Pollution of soil and water resources

• Drain blockages and urban flooding

• Harm to wildlife and marine ecosystems

• Toxic emissions from burning over 5.8 million tonnes of plastic

• Severe waste management challenges in metro cities

The solution requires stronger bans, improved recycling infrastructure, and public education about sustainable waste disposal practices.

Host Country 2025: South Korea Leads the Way

South Korea, specifically Jeju Province, is the official host of World Environment Day 2025. Known for its green living initiatives, Jeju has committed to eliminating plastic waste by 2040. Local efforts include:

• Mandatory waste segregation

• Boosting recycling and eco-tourism

• Hosting global forums, exhibitions, and cleanup campaigns

As host, Korea will guide international dialogue, share successful practices, and promote innovation in reducing plastic dependency.

World Environment Day 2025 serves as a reminder that addressing plastic pollution is a shared responsibility. With South Korea leading the charge and global collaboration rising, this year could mark a pivotal step toward a cleaner, greener future.
