World Environment Day (WED), celebrated annually on June 5, is the United Nations’ flagship platform for promoting global environmental awareness and action. Established in 1972 at the Stockholm Conference on the Human Environment, it engages over 150 countries and millions of people in tackling pressing ecological challenges. In 2025, hosted by the Republic of Korea on Jeju Island, WED focuses on ending plastic pollution under the theme #BeatPlasticPollution. With plastic waste infiltrating ecosystems, food chains, and even human bodies, this year’s campaign calls for collective action to reduce, reuse, recycle, and rethink plastic use. This 2,000-word article explores the significance of WED 2025, the global plastic pollution crisis, the Republic of Korea’s leadership, actionable solutions, and how individuals and communities can join the movement for a cleaner, healthier planet.
The Urgency of Plastic Pollution
Plastic pollution is one of the most pervasive environmental crises of our time. Globally, over 430 million tonnes of plastic are produced annually, with two-thirds becoming short-lived waste that clogs oceans, rivers, and landfills. An estimated 11 million tonnes of plastic leak into aquatic ecosystems each year, equivalent to the weight of 2,200 Eiffel Towers. Microplastics—tiny particles up to 5mm—have infiltrated water, air, and food, with each person consuming over 50,000 particles annually through ingestion and inhalation. More than 800 marine species are harmed by plastic through entanglement, ingestion, and habitat disruption, threatening biodiversity and ecosystem health.
Plastic pollution exacerbates the triple planetary crisis: climate change, biodiversity loss, and pollution. Single-use plastics, which constitute half of global production, contribute to greenhouse gas emissions during production and disposal. In human health, microplastics are linked to respiratory issues and potential toxicity, raising concerns about long-term impacts. Yet, as the United Nations Environment Programme (UNEP) emphasizes, plastic pollution is “one of the most fixable environmental challenges” due to available solutions like recycling, biodegradable alternatives, and policy reforms. WED 2025, coming two months before the next session of negotiations for a global plastic pollution treaty in Geneva, aims to galvanize action to address this crisis.
World Environment Day 2025: A Global Call to Action
Led by UNEP since 1973, World Environment Day is the largest global platform for environmental outreach, celebrated in over 150 countries with events like clean-ups, tree plantings, and policy discussions. In 2025, the Republic of Korea hosts the event on Jeju Island, marking its second time as host since 1997, when the theme was “For Life on Earth.” The 2025 campaign, centered on #BeatPlasticPollution, encourages governments, businesses, communities, and individuals to adopt sustainable practices and advocate for systemic change.
The timing is critical. In November 2024, Korea hosted the fifth session of the Intergovernmental Negotiating Committee (INC-5) to develop a legally binding global treaty on plastic pollution, with the second part scheduled for August 2025 in Geneva. Described as the most significant environmental multilateral deal since the Paris Agreement, the treaty aims to address the full lifecycle of plastics, from production to disposal. WED 2025 amplifies this momentum, spotlighting solutions and showcasing real-world actions to curb plastic waste.
The Republic of Korea’s Leadership
The Republic of Korea is a fitting host for WED 2025, given its robust environmental policies and leadership in tackling plastic pollution. Over the past three decades, the country has improved air and water quality, managed chemicals safely, and restored ecosystems. Its full lifecycle plastic strategy addresses production, design, consumption, reuse, and recycling, engaging businesses through extended producer responsibility (EPR) programs. Jeju Province, the event’s location, is a pioneer in waste management, aiming to be plastic-pollution-free by 2040. It mandates waste separation at recycling centers and introduced a disposable cup deposit system, boosting recycling rates.
Korea’s Ministry of Environment launched the WED 2025 Action Campaign on May 1, 2025, encouraging individuals to pledge environmental actions like reducing plastic use and participating in “plogging”—picking up trash while jogging. Participants who post plogging videos on social media with hashtags #WorldEnvironmentDay and #BeatPlasticPollution by May 21 can enter a draw for mobile gift vouchers, with select videos featured at the June 5 ceremony at the International Convention Center Jeju. The ministry also established a Task Force on March 4, 2025, led by Lee Hyeong-seop, to ensure comprehensive planning for the event.
The Global Plastic Pollution Crisis: Impacts and Challenges
Plastic pollution’s far-reaching impacts demand urgent action. Below are key challenges highlighted by WED 2025:
Environmental Degradation
Plastic waste pollutes every ecosystem, from mountain tops to ocean floors. In aquatic environments, plastics entangle marine life and break down into microplastics, which accumulate in food chains. On land, microplastics from sewage and agricultural products degrade soil health, affecting crop yields and biodiversity. Without intervention, plastic waste in aquatic ecosystems could triple by 2040.
Human Health Risks
Microplastics have been detected in human blood, lungs, and breast milk, raising concerns about toxicity and long-term health effects. Discarded or burnt plastics release harmful chemicals, contributing to air pollution that causes an estimated 7 million deaths annually, particularly in the Asia-Pacific region. Workers in plastic production and waste management face hazardous exposures, prompting the International Labour Organization to call for safer working conditions.
Climate and Biodiversity Impacts
Plastic production relies on fossil fuels, contributing to greenhouse gas emissions. The loss of biodiversity due to plastic pollution undermines ecosystems’ ability to sequester carbon, exacerbating climate change. WED 2025 emphasizes that ending plastic pollution supports Sustainable Development Goals (SDGs) on climate action, sustainable consumption, and biodiversity protection.
Socioeconomic Barriers
While solutions exist, challenges like inadequate waste management infrastructure, especially in developing nations, and resistance from industries reliant on single-use plastics hinder progress. The global treaty negotiations aim to address these barriers by fostering international cooperation and financing mechanisms.
Solutions to Beat Plastic Pollution
WED 2025 showcases practical solutions to reduce plastic pollution, drawing inspiration from nature and global best practices. Below are key strategies:
