**The Global Circular Ocean Pact: A 4-Pillar Strategy**
1. **Stop the Flow (Top 100 Rivers):** Deploy autonomous, solar-powered interceptor barriers at the mouths of the 100 rivers responsible for 80% of ocean plastic inflow. This halts new pollution immediately.
2. **Standardize & Tax:** Implement a global tax on virgin plastic resin to fund cleanup. Mandate a reduction of plastic types to just 3 standardized, easily recyclable polymers (PET, HDPE, PP) to streamline global recycling infrastructure.
3. **Extended Producer Responsibility (EPR 2.0):** Legally bind manufacturers to a "1-for-1" recovery mandate—for every ton of plastic produced, one ton must be verified as recovered or recycled, tracked via blockchain supply chain transparency.
4. **Bio-Replacement:** Subsidize mass production of seaweed-based and fungal-mycelium packaging to replace single-use plastics in food and retail sectors by year 5.
This integrated approach attacks the source, cleans the legacy, and closes the loop.
