MICRO-PLASTICS

Microplastics pose a growing threat to ecosystems and human health. Discuss their impacts and measures to address them.

Model Answer

Introduction

Microplastics are plastic particles generally smaller than 5 mm, arising from both manufactured products and the breakdown of larger plastics.

Key Impacts

  • Ecological: Ingestion → digestive blockage + pseudosatiety → nutritional stress.
  • Food chain: Carry Persistent Organic Pollutants + heavy metals → ecosystem contamination.
  • Human health: Chemical additives such as Bisphenol A + phthalates may cause endocrine and reproductive concerns.
  • Antimicrobial Resistance: Plastisphere can facilitate exchange of Antibiotic Resistance Genes.
  • Blue economy: Contamination of fisheries → livelihood + trade risks.

Measures

  • Plastic Waste Management (Amendment) Rules, 2024 + 2025 → regulation + traceability.
  • Extended Producer Responsibility → recycled-content targets + producer accountability.
  • United Nations Global Plastics Treaty → global life-cycle approach.
  • Promote plastic reduction + circular economy + better waste management + monitoring.

Conclusion

A source-to-sea approach → reduce plastic use + prevent leakage + improve recycling is essential to control microplastic pollution.
