France's President Macron warns of impending plastic pollution crisis.

French President Emmanuel Macron warns that plastic pollution is a "time bomb" as delegates from 175 nations meet in Paris to sign an international treaty to end plastic waste. Macron called for an end to the unsustainable production model and urged nations to reduce the production of plastics based on fossil fuels and ban single-use plastics. The negotiations will also include NGOs, plastic companies, and lobbyists. Annual plastics production has more than doubled in 20 years to 460 million tonnes, and policy actions to be debated include a global ban on single-use plastic items, "polluter pays" schemes, and a tax on new plastic production.
