It’s not as glamorous as it sounds, but washing and reusing baggies helps keep them out of the landfill and our oceans. As of 2015 there were 5.25 trillion pieces of plastic debris in oceans worldwide.
Reusable food bags are even better, but when you must use plastic (my family relies on baggies and Ziplocs because of multiple food allergies in our household causing our need to keep food separated), try to reuse them at least a few times.
This plastic bag rack works really well and has lasted more than 10 years on my countertop. But even if you don’t have a separate drying rack, washing and drying bags on regular dish drainer works fine.
