Main Viewpoints

\n
    \n
  • Plastic is lightweight, durable, and vital for economic growth and product safety.\\n→ <https://www.bpf.co.uk/press/BenefitsofPlastics.aspx>
    • \n
  • Plastic pollution, especially microplastics, harms marine life and threatens human health and food chains.\\n→ <https://www.nature.com/articles/s41598-021-82593-0>

Main Drivers Behind the Issue

\n
    \n
  • Mass production and disposal of plastic goods
    • \n
  • Global plastic production exceeds 400 million tonnes per year.
    • \n
  • Ineffective waste management systems
    • \n
  • Much plastic ends up in the ocean through mismanaged landfill or waterways.
    • \n
  • Consumer demand for low-cost, single-use products
    • \n
  • Convenience outweighs long-term consequences.
    • \n
  • Lack of global enforcement and coordination
    • \n
  • Patchy regulations and limited accountability.
