Discuss the effects of Plastic pollution on the global climate and human health? How is the Global Plastics treaty, 2022, helpful in controlling the impact of plastic pollution?
Plastic pollution is a pervasive environmental issue that contributes to global climate change and has profound health implications. Every day, the equivalent of 2,000 garbage trucks full of plastic are dumped into the world’s oceans, rivers, and lakes. Plastic pollution is a global problem. Every year 19-23 million tonnes of plastic waste leaks into aquatic ecosystems, polluting lakes, rivers and seas. Plastic pollution can alter habitats and natural processes, reducing ecosystems’ ability to adapt to climate change, directly affecting millions of people’s livelihoods, food production capabilities and social well-being. The Global Plastics Treaty, 2022, emerged as a landmark initiative to address this growing crisis.
Effects on Global Climate
High Carbon Footprint of Plastic Production:
●Plastics are derived from petrochemicals, requiring extraction and refining of fossil fuels.
●The production and transportation of plastic contribute to approximately 3.8% of global greenhouse gas emissions.
●By 2050, plastic production is projected to consume 20% of global oil production, significantly adding to carbon emissions.
Plastic Waste and Greenhouse Gas Emissions:
●Improperly disposed plastics in landfills degrade slowly, emitting methane and ethylene, potent greenhouse gases that contribute to global warming.
Incineration of Plastics:
●Burning plastic waste is a common disposal method, particularly in countries with inadequate waste management systems.
●This releases significant amounts of carbon dioxide (CO₂), as well as other toxic pollutants, aggravating climate change and air pollution.
Microplastics and Oceanic Carbon Cycle:
●Plastics in oceans disrupt marine ecosystems and the carbon sequestration ability of phytoplankton.
●Microplastics absorb pollutants, damage marine life, and indirectly impact the ocean’s ability to regulate the Earth’s climate.
Energy Consumption:
●Recycling plastics, while better than landfilling or incineration, is energy-intensive and contributes to indirect emissions unless powered by renewable energy sources.
Effects on Human Health
Chemical Exposure:
●Plastics contain harmful additives such as phthalates, bisphenol-A (BPA), and flame retardants. These chemicals leach into food, water, and the environment.
●Chronic exposure is linked to endocrine disruption, reproductive issues, developmental disorders, and certain cancers.
Microplastics in the Food Chain:
●Microplastics have been detected in fish, shellfish, and salt, and are ingested by humans through contaminated food and water.
●Accumulation of microplastics in human organs may cause inflammation, immune system disruption, and cellular damage.
Respiratory and Cardiovascular Issues:
●Open burning of plastics releases toxic gases such as dioxins, furans, and fine particulate matter, which are linked to respiratory illnesses, asthma, and cardiovascular diseases.
Plastic Pollution and Mental Health:
●Communities living near polluted rivers, landfills, or incinerators face psychological stress due to environmental degradation, health risks, and social stigma.
Impact on Water Quality and Sanitation:
●Plastics clog drainage systems and contaminate freshwater resources, leading to waterborne diseases and compromised hygiene in underdeveloped regions.
Occupational Hazards:
●Workers in the plastic production and recycling industries are exposed to harmful fumes, increasing the risk of chronic diseases such as lung cancer and neurotoxicity.
The Global Plastics Treaty, adopted in 2022 under the aegis of the United Nations Environment Programme (UNEP), aims to tackle the escalating global challenge of plastic pollution. With a legally binding framework, the treaty seeks to address plastic pollution across its lifecycle—from production to disposal—and mitigate its environmental, economic, and health impacts.
Key Objectives of the Global Plastics Treaty
Ending Plastic Pollution:
●Aimed at eliminating plastic waste from the environment, including marine ecosystems, by addressing both production and post-consumer phases.
Promoting a Circular Economy:
●Encourages recycling, reuse, and sustainable alternatives to reduce dependence on virgin plastic.
Reducing Greenhouse Gas Emissions:
●Regulates plastic production, a significant contributor to carbon emissions, thereby contributing to climate change mitigation.
Establishing Global Standards and Accountability:
●Creates uniform regulations and benchmarks for managing plastic pollution across nations.
Protecting Marine and Terrestrial Ecosystems:
●Focuses on reducing the plastic debris that harms biodiversity and disrupts ecological balance.
Treaty Helps Control the Impact of Plastic Pollution
Comprehensive Regulation Across the Plastic Lifecycle:
●By targeting the entire lifecycle of plastic—from production and consumption to waste management—it ensures holistic mitigation of pollution sources.
Reduction in Virgin Plastic Production:
●Encourages a shift away from fossil-fuel-based plastic production, reducing greenhouse gas emissions and reliance on finite resources.
Promotion of Sustainable Alternatives:
●Stimulates innovation and investment in biodegradable, compostable, and reusable materials.
●Supports businesses transitioning to eco-friendly practices through incentives and subsidies.
Focus on Marine Environment Protection:
●Implements strategies to reduce marine litter, protecting biodiversity and coastal economies dependent on fishing and tourism.
Improving Waste Management Infrastructure:
●Emphasizes the development of robust systems for plastic waste collection, sorting, and recycling, especially in developing countries.
Global Cooperation and Knowledge Sharing:
●Facilitates technology transfer, funding, and best practices among nations to address plastic pollution collaboratively.
Addressing Microplastic Contamination:
●Focuses on mitigating the impact of microplastics in food, water, and air, thereby reducing their health risks to humans and wildlife.
Building Public Awareness:
●Encourages global campaigns to educate individuals and communities about the dangers of plastic pollution and the need for responsible consumption.
Conclusion
The Global Plastics Treaty, 2022, is a groundbreaking initiative to combat the multifaceted crisis of plastic pollution. By focusing on global collaboration, sustainable practices, and accountability, it provides a roadmap for reducing the environmental and health impacts of plastic pollution. However, its success depends on bridging the divide between nations and fostering inclusive, equitable solutions for a sustainable future.
