Around 175 countries could sign a plastic pollution treaty. It will protect the future of our planet. The UN spoke about the problem. It said: "Our world is drowning in plastic. Every year, we produce 460 million tons of it. Much of this is thrown away." The UN said a treaty will help our children and our children's children.

The UN said it was important to act now. By 2050, there could be more plastic than fish in the ocean. Microplastics are creating many new health problems. South Korea asked countries to aim for zero plastic pollution. It said: "The waste…in our oceans and rivers now [risks] the lives of future generations."
