Amazon is trying to eliminate plastic that doesn't get recycled. It's actually making some progress.

• Amazon said nearly all deliveries in North America no longer have plastic air pillows inside.
• This change avoids 15 billion air pillows a year, Amazon's biggest plastic reduction effort yet.
• Companies are under pressure to reduce single-use plastics that pollute the environment.
