Why stop at plastic bags and straws? The case for a global treaty banning most single-use plastics

Single-use plastics are a blessing and a curse. They have fueled a revolution in commercial and consumer convenience and improved hygiene standards, but also have saturated the world’s coastlines and clogged landfills. By one estimate 79 percent of all plastic ever produced is now in a dump, a landfill or the environment, and only 9 percent has been recycled.
This growing legacy poses real risks. Plastic packaging is clogging city sewer systems, leading to flooding. Abandoned plastic goods create breeding grounds for mosquitoes, and can leach toxic additives such as styrene and benzene as they decompose. Single-use plastics are killing birds and harming marine life.
I study international environmental law with a focus on marine ecosystems. In my view, land-based pollution from single-use plastics is a slow-onset disaster that demands a global response.
One attractive strategy is pursuing a legally binding phase-out of most single-use plastics at the global level. I believe this approach makes sense because it would build on current national and municipal efforts to eliminate single-use packaging, and would create opportunities for new small and medium-sized businesses to develop more benign substitutes.
