It's not the biggest lever we can pull, but it does feel better to know that if you were to replace your car with a bicycle, if we had no plastic tires we could almost feel like outside the fixed carbon emissions costs in the manufacturing of components, we'd be mostly pollution-free in our personal transportation (ignoring the implicit costs of the other products we use and their transportation).

The idea that I could take one additional bike ride and not have to know that it's going to create a marginal increase in plastic pollution is a beautiful one.
