 It's Morning Edition from NPR News. I'm Sasha Pfeiffer. And I'm A. Martinez. Can you go a whole month without using any plastic? Well, that's the challenge issued by the Plastic Free Foundation, a nonprofit based in Australia. This month, they're calling on people all over the world to avoid single-use plastics. About a quarter of those plastics will end up as litter, according to Oxford University's Our World in Data, and also take anywhere from 20 years to even as long as centuries to decompose.
