Plastic waste is everywhere. Each year, around 400 million metric tons of it end up in landfills and places like oceans, rivers and shorelines. The trash breaks down into tiny pieces called microplastics that have made their way into every corner of the environment and even into human bodies.
The problem is getting worse. So last year the United Nations set out to write a legally binding agreement to deal with the issue. That decision by U.N. member states "will clearly take us towards a future with no plastic pollution," Tsuyoshi Yamaguchi, Japan's then-environment minister, said at the time.
