“Every time I throw a plastic sandwich bag away, I cringe a little.”

Part of being a responsible adult includes considering the world around you.
You’re a consumer, using the world’s resources to live your daily life. You use the running water in your home to shower, peel the plastic wrappings off new appliances you buy, and drink from La Croix sparkling water cans. So it’s also your responsibility to care about what happens to those things when they leave your possession.
